07 Oct First Week With a Rescue Dog: What to Expect and What to Avoid

You’ve Done a Wonderful Thing. Now What?

You’ve passed the home check, signed the paperwork and driven home with a dog who is either completely frozen with anxiety or attempting to eat the car.

Congratulations! You’ve just adopted a rescue dog and the first few days can feel a bit surreal.

The truth is that the first week with a rescue dog is often far less straightforward than people expect. Some dogs arrive and immediately make themselves at home, they’ll explore every room, test every sofa and act as though they’ve lived there for years and others barely move.

Some follow their new owner like a new shadow and others seem to ignore their new owners.

There are also dogs that can seem settled for the first few days before starting to show how they have strong opinions about being left alone, visitors or outside sounds.

It’s important to know that all of these responses can be normal. It can be a big change for this dog. So the first week is often less about training and more about helping your dog feel safe enough to learn how the new home works.

The good news is that helping a rescue dog settle in doesn’t require perfection. It requires patience, realistic expectations and understanding of your dog’s experience.

First, A Word About the 3-3-3 Rule

If you’ve done some research about rescue dogs, you may have come across something referred to as the 3-3-3 rule.

The idea is simple:

• Around three days to decompress from the move.
• Around three weeks to start settling into a routine.
• Around three months to begin feeling truly at home.

As a rough guide, it’s useful. But, it’s a guideline not a guarantee. Since dogs don’t work to schedule, not every dog follows this structure. Occasionally a dog appears to be setting in really well and suddenly takes a step backwards, this is normal too.

Dogs don’t adjust in a straight line, there may be detours along the way. Essentially this rule means that your dog needs time, patience, consistency and freedom to settle at their own pace. Try not to get caught in what you read online and rush your dog, they are an individual, they’ll get there in their own time.

What to Expect in the First Week

The first week can be challenging as both you and your dog are figuring each other out. Because of that, it’s normal to see behaviours that seem confusing, unexpected or even contradictory. 

They might not each much (or at all) – This is common. Since stress has an effect on appetite and your dog has just had a big change. Even if you’re feeding exactly the same food they had before, everything around that meal is unfamiliar.

Keep offering food at regular times and try not to panic if they’re eating slowly or leaving meals untouched. Most dogs begin eating more normally as they settle and relax. However, if your dog hasn’t eaten anything at all after 48 hours it would be sensible to speak to your vet.

They might have toilet accidents – Even dogs that had previously good toileting habits can have accidents during the first week. It’s not necessarily a sign they weren’t housetrained. Stress affects bodily functions, routines have changed and your dog doesn’t yet know where the toilet is in this new environment.

Treat accidents as if you have a puppy, take them out regularly, praise calmly when they get it right and don’t say anything if they have an accident. 

They might seem shut down or withdrawn – Some rescue dogs arrive and then immediately disappear under a table, behind a sofa or into a corner. Some sit quietly and watch.

They might startle at everyday noises or appear worried by things that seem completely ordinary. This can be part of the decompression process as your dog takes in all the new information and determines if they find it safe. It’s important not to force interaction or pressure them to be sociable. A quiet, predictable environment is what they need initially. 

Or they might seem absolutely fine…then change – This is the one that catched many owners off guard. Some rescue dogs arrive and seem completely settled from the moment they arrive as they’re friendly, relaxed and confident. Then sometime later different behaviours start to appear, they become more anxious or less comfortable around visitors. This is sometimes referred to as the ‘honeymoon period’ ending. Your dog isn’t suddenly becoming difficult but rather comfortable enough to communicate. 

A dog who is too overwhelmed to express their feelings in the beginning may start showing those feelings once they feel safe enough to do so, so this behaviour can actually be a sign they’re beginning to settle. 

They might test every boundary going – Not every rescue dog will do this but some will. Partially dogs who have not had much of a routine before. Attention seeking behaviours start to emerge as dogs will repeat behaviours that work. Whether that be attention, or it resulted in food or some other success then the dog will consider repeating it.

Week one isn’t about creating a perfectly trained dog but establishing routines, setting sensible boundaries and managing the environment to help your dog succeed. Training will come but initially focus on helping your dog settle in and learn how this new life and home works.

What Actually Helps 

Give them a safe space – Whether this be a crate, a bed, a quiet corner or room they can retreat to. Somewhere that’s theirs where it’s a guarantee that no one will bother them. This is particularly important if there are children in the home. A safe space gives your dog control over their environment. Make sure everyone in the home understands that when the dog chooses to use that space this is to be respected.

Give them a safe space – This should include mealtimes, walks or quiet time. Dogs settle faster when they can start to predict what happens next. Be aware you don’t need a perfect schedule, just let it be reasonably consistent.  

Let them sniff – Sniffing is decompressing for dogs. A slow, calm sniff walk, even if it’s just around the block, is often more beneficial in the first week than a long energetic run. Snidding is one of the ways dogs gather information about their environments and help them feel more comfortable in it.

Reward the behaviour you like – You don’t need formal training sessions yet, but you should notice and reward good moments. This can be anything you want to encourage such as settling quietly or being calm around children. The reward can be things like calm, gentle vocal praise or treats. This helps start building a positive relationship without putting pressure on the dog while they are still finding their feet.

Be patient with yourself too – The first week is a lot. That’s completely normal so be sure to give yourself the same grace you’re giving your dog. You’re both adjusting to a big change and you’re both learning as you go.

When to Get Professional Support

The first week is generally about patience, management and allowing your dog time to decompress rather than focusing on training. That said, there are situations where getting professional support sooner rather than later is the right thing to do. Don’t wait until a problem is serious before asking for help. 

Consider reaching out to a qualified trainer or behaviourist if;

• Your dog is showing signs of aggression.
• If your dog seems terrified rather than simply unsettled and you’re not seeing any gradual improvement.
• You have concerns about how they’re interacting with children, other dogs or pets in the home.
• You’re feeling overwhelmed or unsure how best to handle what you’re seeing.

A good trainer or behaviourist won’t judge you for reaching out early. In fact, it’s often much easier to help a dog settle successfully from the beginning than it is to unpick behaviours that have had time to become established. Asking for support is not a sign you’re failing your dog and it’s often one of the best ways to help them succeed in their new home.

The Bit That’s Worth Remembering

Rescue dogs don’t come with a manual and don’t always come with a clear history.

Be gentle, stay consistent. Give both of you time to figure each other out.
