I adopted my dog without asking enough questions. The shelter said he was “good with other dogs.” Turns out that meant “good with other dogs who completely ignore him.” He’s dog-reactive on leash, which I discovered on day two when he lunged at a golden retriever in the park. Three months of training later, he’s doing much better, but those first weeks were stressful for both of us.
Adopting a dog is one of the best things you can do. Shelters are full of incredible dogs that need homes, and the bond you build with a rescue is genuine. But adoption shouldn’t be impulsive. A dog is a 10 to 15 year commitment that affects your schedule, your budget, your living situation, and your daily routine. Walking in prepared means a smoother transition for you and a more stable home for the dog.
These 15 questions will help you evaluate whether you’re ready, find the right match, and set both of you up for success from day one.
Before You Visit the Shelter
Some honest self-assessment prevents you from falling in love with the wrong dog for your situation.
- Be realistic about your daily schedule. Dogs need time. Puppies need a lot of time. If you work 10-hour days with a commute, a high-energy puppy that needs to go outside every two hours isn’t going to work without a dog walker or daycare.
- Check your lease or HOA rules. Many rentals and HOAs have breed restrictions, weight limits, or pet deposits. Violating these can mean rehoming the dog or losing your housing. Know the rules first.
- Calculate the financial commitment. The ASPCA estimates the average annual cost of dog ownership at $1,500 to $2,000+ for food, vet care, grooming, and supplies. Emergency vet bills can run $2,000 to $5,000+ for a single incident. Know whether your budget can handle this.
- Consider everyone in the household. Allergies, fear of dogs, young children, other pets. Every person and animal in your home is affected by this decision. Get everyone on board before you start looking.
- Think about your lifestyle honestly. Do you travel frequently? Work long hours? Live in a studio apartment? Love hiking every weekend? The right dog matches your real lifestyle, not the lifestyle you wish you had.
What to Mention or Send Beforehand
When you contact a shelter or rescue, share these details so they can help match you with the right dog:
- Your living situation (house with yard, apartment, condo)
- Whether you have other pets and their temperaments
- Whether you have children and their ages
- Your activity level and typical daily schedule
- Any breed preferences or size limitations
- Your previous experience with dogs
The Dog’s Background and Temperament
1. What do you know about this dog’s history and how they ended up here?
A dog’s background gives you insight into what to expect. Was it surrendered by an owner (and why)? Found as a stray? Transferred from another shelter? Rescued from a hoarding or neglect situation?
Dogs surrendered because of a move or financial hardship often adjust well because they’ve lived in a home before. Dogs rescued from neglect or abuse may need more patience, training, and time to decompress. Strays are wildcards. They can be incredibly resilient and adaptable, or they may have unknown behavioral quirks. The shelter may not know much, and that’s okay, but whatever they do know helps you prepare.
2. How does this dog behave with other dogs, cats, and children?
This question has layers. “Good with dogs” can mean anything from “plays enthusiastically” to “ignores other dogs” to “tolerates them but isn’t friendly.” Ask for specifics.
Has the shelter done a dog-to-dog introduction? How did it go? Does the dog live in a foster home with other animals? Has the dog been around children, and how did it react? If you have cats, a dog with high prey drive is risky. If you have young kids, a dog that’s mouthy or easily startled needs careful management. Ask the shelter staff or foster family for honest, detailed answers. They’d rather you know the truth than have the dog returned in two weeks.
3. What is the dog’s energy level, and how much exercise does it need?
Energy level is one of the most common reasons for adoption returns. A high-energy dog in a low-energy household is destructive and anxious. A low-energy dog with an avid runner is just a disappointment.
Ask about daily exercise needs: Is this a 20-minute walk dog or a 2-hour hike dog? How does the dog behave when under-exercised? Some dogs get destructive. Others get vocal. Some develop anxiety behaviors like excessive licking or pacing. Match the dog’s energy to your real daily capacity, not your best-day capacity.
4. Does this dog have any known behavioral issues?
Shelter dogs commonly display: separation anxiety (destructive behavior when left alone), leash reactivity (barking or lunging at other dogs or people on walks), resource guarding (growling over food or toys), fear of specific triggers (men, loud noises, hats, umbrellas), and house training gaps.
None of these are dealbreakers, but they all require work. Ask what the shelter has observed, what the foster family has noted, and what training has already been done. Then honestly assess whether you’re willing and able to work through those issues. A good training treat pouch filled with high-value treats makes behavior modification much more manageable.
Health and Veterinary
5. What is the dog’s health history, and are vaccinations current?
Ask for the dog’s complete medical record. This should include: vaccination history (rabies, DHPP, bordetella), spay/neuter status, heartworm and flea/tick treatment, any diagnosed conditions, and recent veterinary exams.
Many shelters include basic vaccinations, spay/neuter, and a microchip in the adoption fee. That’s often $200 to $500 worth of veterinary work included in a $100 to $300 adoption fee. It’s one of the best deals in dog ownership. Ask specifically about heartworm status, since treatment for heartworm disease costs $1,000 to $3,000 and is hard on the dog.
6. Does this dog have any ongoing medical conditions that require treatment?
Some shelter dogs have manageable but chronic conditions: allergies (requiring special food or medication), hip dysplasia (common in larger breeds), dental disease (needing extractions), epilepsy (requiring daily medication), or skin conditions.
These conditions don’t make a dog less lovable, but they do affect your budget and commitment. A dog with allergies might need $50 to $150/month in special food and medications. A dog with hip dysplasia may eventually need surgery ($3,000 to $7,000). Know what you’re signing up for so you can provide the care the dog deserves.
7. How old is this dog, approximately, and what is the expected lifespan?
Age affects energy level, training ease, and expected time together. Puppies (under 1 year) are adorable and demanding. They need house training, socialization, basic obedience, and constant supervision. Adult dogs (1 to 7 years) are often the best adoption choice: personality is established, training is easier, and they’re past the destructive puppy phase. Senior dogs (7+ years) are calmer, often already trained, and deeply appreciative of a comfortable home, but may have higher vet costs and shorter time together.
Small breeds live 12 to 16 years. Medium breeds live 10 to 14 years. Large and giant breeds live 7 to 12 years. These are averages, and individual dogs vary. Consider how your life might change over the dog’s lifetime when making your decision.
Logistics and Preparation
8. What does the adoption process involve, and how long does it take?
Adoption processes vary by organization. Some shelters do same-day adoptions. Others require an application, home visit, reference checks, and a waiting period. Breed-specific rescues tend to have the most rigorous processes.
Ask about: the application timeline, any required home visit, whether there’s a meet-and-greet with your current pets, the adoption fee and what it includes, and any post-adoption support the organization provides. Don’t be put off by a thorough process. Organizations that screen carefully are trying to ensure lasting placements, which benefits you and the dog.
9. What supplies do I need to have ready before bringing the dog home?
Your house should be set up before the dog walks through the door. Scrambling for supplies while a new dog is exploring (and possibly anxious) isn’t ideal.
Essential supplies: a properly sized dog crate for safe decompression and house training, food and water bowls, the same food the dog has been eating (switching food abruptly causes stomach issues), a collar with ID tags and a sturdy leash, a comfortable dog bed, poop bags, basic grooming supplies (brush, nail clippers), and enzymatic cleaner for accidents (they will happen).
10. Is there a trial period or return policy?
Most reputable shelters and rescues have a return policy. Many offer a two-week trial period. Some accept returns at any point in the dog’s life, no questions asked.
This isn’t a “test drive.” It’s a safety net. Sometimes a dog’s behavior in a shelter environment is completely different from behavior in a home. A dog that seemed calm at the shelter might have severe separation anxiety at home. A dog that seemed dog-friendly might have issues with your specific cat. Knowing you have a return option takes the pressure off and, ironically, makes the adoption more likely to succeed because you’re not trapped if there’s a genuine incompatibility.
Long-term Commitment
11. What are the expected annual costs, and am I prepared for emergencies?
Budget honestly. Annual costs for a medium-sized dog in 2026:
- Food: $500 to $1,200
- Routine vet care (exams, vaccines, preventatives): $300 to $700
- Grooming: $0 to $600 (depends on breed)
- Flea/tick/heartworm prevention: $150 to $300
- Supplies and toys: $100 to $300
- Pet insurance (optional but recommended): $300 to $700
Total baseline: $1,350 to $3,800 per year.
Emergency vet visits are the wildcard. A foreign body surgery (when a dog eats something it shouldn’t) runs $2,000 to $5,000. A torn ACL is $3,000 to $6,000. Cancer treatment can exceed $10,000. Pet insurance or an emergency savings fund ($2,000 to $3,000 set aside) provides a buffer. Without either, a single emergency can force an impossible financial decision.
12. How will this dog fit into my daily routine and living situation?
Walk through a typical day honestly. When will the dog go outside first thing in the morning? Who handles the midday walk or bathroom break if you work outside the home? Where will the dog be while you’re working? What about evenings, weekends, and vacations?
If you work from home, a dog fits naturally into your day. If you commute, you need a plan for the hours you’re gone: a dog walker ($15 to $25 per walk), doggy daycare ($25 to $50 per day), or a trusted neighbor. Dogs shouldn’t be left alone for more than 6 to 8 hours, and many dogs struggle with anything over 4 hours.
13. Am I prepared for the training commitment, especially in the first few months?
Every adopted dog needs some level of training and adjustment, even well-behaved adults. The “3-3-3 rule” is a useful framework: the first 3 days, the dog is overwhelmed and may shut down or act out. The first 3 weeks, the dog starts showing its real personality and testing boundaries. The first 3 months, the dog settles into a routine and begins to trust you.
Budget time and potentially money for training. Group obedience classes run $100 to $300 for a 6-week course. Private trainers charge $75 to $200 per session. At minimum, invest in basic obedience (sit, stay, come, leave it) and work on any specific behavioral issues the shelter identified.
After Adoption
14. What post-adoption support does the organization offer?
Good shelters and rescues don’t disappear after you sign the papers. Many offer: behavioral consultations, training resources or discounts with partner trainers, a vet visit within the first two weeks, and a community of adopters for advice and support.
Ask specifically what’s available. Some rescues have volunteer trainers. Others partner with local training facilities for discounted classes. A few provide behavioral hotlines for the first 30 days. This support can make the difference between a successful transition and a returned dog.
15. What should I expect during the first two weeks at home?
The first two weeks are a decompression period, not a honeymoon. Your new dog may: refuse to eat for the first day or two, have accidents in the house (even if house-trained), be fearful or shut down (hiding, trembling, avoiding you), be over-excitable and test every boundary, or sleep excessively.
All of this is normal. Give the dog space, establish a routine, keep things calm, and don’t overwhelm them with new people, places, or experiences. Short walks, quiet time, consistent meal times, and a safe crate or bed to retreat to are the foundations. The real dog, the one with personality and affection and goofiness, shows up after the decompression period. Be patient.

Red Flags vs. Green Flags
| Red Flag | Green Flag |
|---|---|
| Shelter discourages questions or rushes the adoption process | Staff takes time to answer questions thoroughly and honestly, including about behavioral challenges |
| No medical records available, or the dog hasn’t seen a vet | Complete medical records including vaccinations, spay/neuter, and heartworm test |
| Shelter says “perfect dog, no issues at all” about every dog | Staff gives honest, specific descriptions of each dog’s strengths and challenges |
| No return policy or trial period | Clear return policy and support if the adoption doesn’t work out |
| Dog hasn’t been temperament-tested or evaluated | Dog has been assessed for behavior with people, other dogs, and (if applicable) cats |
| Adoption fee seems suspiciously low with no included vet work | Adoption fee includes spay/neuter, vaccines, microchip, and initial vet exam |
| No post-adoption support or resources | Post-adoption behavioral support, training resources, and community connection |
| Pressure to adopt immediately without time to think | Encourages you to take time, meet the dog multiple times, and involve your family |
Money-Saving Tips
- Adopt, don’t shop. Adoption fees ($50 to $500) include vet work that would cost $200 to $800 if purchased separately. A “free” dog from a friend still needs all that vet work out of your pocket.
- Get pet insurance in the first month. Pet insurance is cheapest when the dog is young and healthy. Pre-existing conditions are excluded, so insuring early provides the broadest coverage. Plans run $30 to $60/month and can save thousands on a single emergency.
- Buy supplies during sales events. Amazon Prime Day, Black Friday, and Chewy’s periodic sales offer 20 to 40% off food, treats, and supplies. Stock up when prices drop.
- Learn basic grooming at home. A $30 set of dog clippers and a $10 brush handle most grooming needs for short and medium-coat dogs. Professional grooming at $50 to $80 per visit adds up fast.
- Use your vet’s preventive care plan. Many vets offer wellness plans ($25 to $50/month) that bundle annual exams, vaccines, and dental cleanings at a discount versus paying for each service individually.
- Make toys instead of buying them. A frozen Kong stuffed with peanut butter entertains a dog longer than most $15 toys. Old t-shirts braided into rope toys work just as well as store-bought versions.
Glossary
Spay/Neuter: Surgical sterilization to prevent reproduction. Spaying (females) and neutering (males) also provide health benefits (reduced cancer risk) and behavioral benefits (less roaming, less marking). Most shelters require or perform this before adoption.
Heartworm: A parasitic worm transmitted by mosquitoes that lives in the heart and lungs. Left untreated, heartworm disease is fatal. Prevention is a monthly pill or annual injection ($50 to $200/year). Treatment for an active infection is $1,000 to $3,000 and involves months of restricted activity.
Microchip: A tiny electronic chip (about the size of a grain of rice) implanted under the dog’s skin, usually between the shoulder blades. It contains a unique ID number linked to your contact information in a database. If your dog is lost and found, any vet or shelter can scan the chip and contact you.
Crate Training: Teaching a dog to view its crate as a safe, comfortable space rather than a punishment. Properly crate-trained dogs rest calmly in their crate, which helps with house training, separation anxiety management, and providing a stress-free retreat.
Decompression Period: The initial adjustment period (typically two weeks to three months) when a newly adopted dog acclimates to its new home. During decompression, dogs may exhibit unusual behaviors that don’t reflect their long-term personality. Patience and routine are essential.
Reactivity: An overreaction to a stimulus (other dogs, strangers, loud noises) that exceeds what’s normal for the situation. Reactive dogs may bark, lunge, growl, or pull excessively. Reactivity is a behavioral issue that can be managed with training, not a sign of aggression.
Helpful Tools and Resources
A crate gives your new dog a safe space to decompress. The divider lets you adjust the size as a puppy grows. Collapsible design makes storage and travel easy. Essential for the first few months.
A 6-foot leash gives you control without restricting the dog too tightly. Reflective stitching adds safety for evening walks. Avoid retractable leashes for newly adopted dogs since you need consistent control during the adjustment period.
A comfortable bed gives your dog a designated resting spot outside the crate. Orthopedic foam helps dogs with joint issues (common in shelter dogs). A washable cover is essential for the inevitable mess of the first few weeks.
Small, soft, smelly treats are the currency of dog training. High-value treats (freeze-dried liver, cheese bites) get a dog's attention even in distracting environments. Essential for the first months of bonding and obedience training.
- Petfinder: Search adoptable dogs across thousands of shelters and rescues nationwide. Filter by breed, age, size, and location. Most listings include photos and detailed descriptions.
- ASPCA Pet Care Resources: Free guides on dog behavior, training, nutrition, and health. Their cost calculator helps you budget for first-year and ongoing expenses.
- r/dogtraining (Reddit): An active community focused on positive reinforcement training methods. Great for specific behavioral questions and real-world advice from experienced dog owners.

Frequently Asked Questions
Should I adopt a puppy or an adult dog?
For most first-time adopters, an adult dog (2 to 5 years old) is the better choice. Their personality is established, they’re often already house-trained, and their energy level is predictable. Puppies are adorable but require significant time for house training, socialization, teething management, and basic obedience. If you work full-time outside the home, an adult dog is almost always the easier adjustment.
Are shelter dogs harder to train than puppies from breeders?
No. In fact, many shelter dogs are adults who already know basic commands. Dogs that do need training respond well to positive reinforcement methods regardless of their background. The myth that shelter dogs are “broken” is exactly that, a myth. They’re dogs who need a stable home and clear, consistent guidance.
How long does it take for an adopted dog to adjust to a new home?
The 3-3-3 rule is a helpful guideline: 3 days to decompress from the shelter experience, 3 weeks to learn your routine and start showing their real personality, and 3 months to feel fully at home and bonded. Some dogs adjust faster, some slower. Patience during this period is the single most important thing you can provide.
What if the adopted dog doesn’t get along with my existing pet?
Slow introductions are key. Keep the new dog separate for the first few days. Exchange scents (swap bedding). Do parallel walks with dogs on leash (separate handlers). Introduce through a baby gate before face-to-face contact. If there’s genuine aggression (not just nervous barking), consult a professional trainer before proceeding. Most introductions work with patience and proper protocol.
Can I adopt a dog if I live in an apartment?
Absolutely. Many dogs thrive in apartments, especially low-to-moderate energy breeds and older dogs. The key is providing enough exercise and mental stimulation through daily walks, training sessions, and enrichment activities. A small dog in a well-exercised apartment household is often happier than a big dog in a yard who gets ignored.
