Bringing home a rescue dog is exciting, but the early weeks can look different than many adopters expect. A dog who seemed calm at an adoption event may pace, hide, or skip meals once they arrive in a new household. Another may seem shy for weeks before a playful personality emerges. These changes are usually a normal part of rescue dog behavior during the adjustment period. Knowing what to expect makes it easier to respond with patience and help your new companion feel at home.
Common rescue dog behaviors during the adjustment period
A newly adopted rescue dog may temporarily:
- Not eat normally
- Drink more or less than usual
- Sleep excessively
- Pace, pant, or whine
- Follow someone constantly
- Hide
- Have potty accidents
- Bark unexpectedly
- Test boundaries
- Pull on the leash
- Guard food or toys
- Become more energetic after several days
- Ignore toys at first, then later start playing
- Ignore other dogs at first, then later become interested
- Seem extremely calm at first, then later become playful or energetic
Many of these behaviors fade as your dog settles into a routine. If a behavior concerns you, persists, or gets worse, see the section on getting help below.
Why your dog may act differently at home
The environment plays a large role in how a dog behaves. Shy and fearful dogs in particular may not show their full range of behavior right away, whether they’re in foster care, at an adoption event, or in their first days with you. That’s why we describe our dogs based on what we’ve observed. For example, instead of promising that a dog never barks, we’ll share that we haven’t heard them bark while in our care.
Watching your dog’s personality emerge
A nervous dog may seem incredibly calm at an adoption event. Two weeks later, that same dog may be racing around the house, playing with toys, barking at squirrels, and stealing socks. This doesn’t mean anything went wrong or that the dog was misrepresented. More often, it means your dog finally feels safe enough to be themselves.
Introducing your rescue dog to other dogs
Introductions with a resident dog should be controlled and gradual. Best Friends Animal Society recommends starting with calm handlers and plenty of space between the dogs rather than forcing face-to-face contact. Pick up high-value items like toys, chews, and bones at first, and feed the dogs separately until you have a better sense of how they interact.
Even if both dogs are friendly, don’t assume they’ll bond immediately. Relationships take time. For step-by-step guidance, see Best Friends’ guide to introducing dogs to each other.
Helping children and rescue dogs get along
A newly adopted dog needs space, and children should understand that before the dog arrives. Help your kids avoid:
- Hugging the dog
- Climbing on the dog
- Putting their faces near the dog’s face
- Taking food or toys away
- Waking a sleeping dog
- Cornering or chasing the dog
Adults should supervise all interactions, especially while everyone is still learning about one another.
What rescue dogs need most
Whether a dog came from a loving home, the street, neglect, abuse, or a hoarding situation, most newly adopted dogs benefit from the same basic things:
- Patience. Some dogs adjust in days, while others need weeks or months.
- Routine. Predictable mealtimes, walks, and bedtimes help your dog learn what happens next.
- Consistency. Everyone in the household should follow the same rules and use the same cues.
- Safety. A quiet space of their own, such as a crate or a bed in a low-traffic room, gives your dog somewhere to decompress.
- Positive reinforcement. Reward the behaviors you want to see. Best Friends recommends positive-reinforcement training rather than punishment.
- Reasonable expectations. Progress isn’t always steady, and setbacks are normal.
- Time. Above all, your dog needs time to learn that this is home.
Don’t expect perfection on day one
Your new dog has just experienced another enormous change. They don’t yet know:
- Who you are
- Where they are
- Whether they’re staying
- What your rules are
- Where they’re supposed to sleep
- When they’re going to eat
- Whether you’ll come back when you leave
Dogs learn these things through repetition and consistency.
When to get extra help
If your rescue dog’s behavior worries you or isn’t improving over time, reach out for support early. Your veterinarian can check for medical issues that may affect behavior. For training and behavior support, the Certification Council for Professional Dog Trainers (CCPDT) and the International Association of Animal Behavior Consultants (IAABC) both offer directories of credentialed professionals.
Their past doesn’t define their future
A dog’s history can offer helpful information, but history doesn’t determine their future.
- A dog from a hoarding situation can become a wonderful family companion.
- An abandoned dog can become secure.
- A fearful dog can gain confidence.
- An owner-surrendered dog can bond deeply with a new family.
- A returned dog can find the perfect home.
Rescue is about giving each dog the opportunity to show you who they can become once they feel safe.
