Bringing Your New Dog Home:

Why a Puppy and a Rescue Dog Need Very Different Starts

In my last post, we talked about how to choose the right dog for your family. So let’s say you’ve done it. The lead is bought, the bed is in the corner, and the dog has already been renamed three times by different members of the household. Now comes the part nobody quite prepares you for: the first few weeks.

There’s plenty of advice out there about teaching a new dog to sit, stay and walk nicely on a lead. That all has its place. But as a behaviourist, the first question I ask isn’t “what can this dog do?” It’s “how is this dog feeling?”

How a dog settles into a new home has far less to do with obedience than with what’s going on inside them: their emotional state, their history, and sometimes their health. And that looks very different depending on where your dog has come from.

Dog trainer or dog behaviourist: what’s the difference?

Both have their place, and plenty of owners need both.

A trainer teaches skills: sit, stay, recall, walking nicely on a lead. A behaviourist works on the other side of it - investigating and treating behavioural and emotional problems. Why is this dog frightened of the hallway? Why won’t it eat? Why does it growl when you reach for its collar? And, just as importantly, is something hurting?

When a new dog hides behind the sofa, cries all night or snaps when you touch its bed, those aren’t problems you can fix with a command. They’re your dog telling you how it’s coping. Understanding that message early is what stops a wobbly start turning into a long-term problem.

How to check someone is qualified

It’s worth knowing that in the UK these job titles aren’t legally protected, so anyone can call themselves a behaviourist. Before you book with anyone, ask what qualifications they hold, what experience they have with problems like yours, whether they’re registered with a recognised body such as the Animal Behaviour and Training Council, and whether they work on veterinary referral. Any good practitioner will be glad you asked.

Bringing home a new puppy

A puppy arrives with very little history, which is a gift. But it’s also arriving at the most sensitive stage of its life. Everything it experiences in these early months helps shape how it sees the world as an adult.

What a puppy needs most

• Gentle, positive introductions to everyday life. The hoover, the car, visitors, other dogs, the clatter of a busy kitchen. Quality matters far more than quantity: one calm experience beats ten overwhelming ones.

• Lots of sleep. Puppies need much more rest than most people expect. An overtired puppy is often a nippy, frantic one, and what looks like “naughtiness” is frequently exhaustion.

• Short spells alone from the start. That way, being on their own becomes an ordinary part of life rather than something to fear.

Signs a puppy is struggling

A puppy who seems permanently on edge, who struggles to bounce back after a fright, or who suddenly becomes grumpy about being handled. Teething, tummy upsets and growing pains can all affect how a puppy behaves. So a sudden change deserves a check with your vet as well as a closer look at what’s happening at home.

Why isn’t my rescue dog settling?

A rescue dog arrives with a story, and often you’ll only ever know part of it. They may have lost the only home and people they knew. They may have spent weeks in kennels, which even the best-run centres can’t make feel like home. Some will have been through experiences that have left real emotional damage.

That’s why I encourage rescue owners to think of the first weeks as decompression, not training. Your new dog needs time to work out that this place is safe, and that can’t be rushed.

How to help a rescue dog settle in

• A quiet, predictable routine, so your dog can start to anticipate what happens next.

• A safe space they can retreat to without being followed or disturbed.

• Letting them come to you, rather than you going to them.

• Holding off on visitors, busy walks and big days out until they’ve found their feet.

Signs your rescue dog isn’t coping

Not eating, hiding, pacing or being very clingy. And one that people most often miss: being “too good”. A dog who is unusually quiet and still in the first few days may be shut down rather than settled.

Many rescue dogs show more of their true personality, including their worries, a few weeks in, once they feel secure enough to do so. That isn’t the dog “turning”. It’s the dog starting to trust you enough to be honest.

Example  A middle-aged rescue from a working background spent her first fortnight curled up in her bed, only eating once the house was quiet at night. Her family thought they’d found the easiest dog in the world. In week four, she started barking at every visitor. She wasn’t becoming difficult; she’d simply relaxed enough to show how frightened she was of strangers. With space, patience and a plan built around that fear, she gradually learned visitors weren’t a threat.

Rehoming an older dog

Not every new dog is a puppy or a rescue. You might be taking on an older dog from a breeder, a relative’s dog they can no longer care for, or a dog retiring from a working life.

These dogs can seem straightforward because they’re past the puppy stage. But they’ve still lost everything familiar: their people, their routine, the smells of home and sometimes their job. Some are grieving. Some have, quite simply, lost their way for a while. They deserve every bit as much patience as a dog from a rescue centre.

Could my dog’s behaviour be caused by pain?

This is the question I come back to again and again. Pain and illness are among the most common, and most overlooked, reasons for changes in behaviour.

A dog who growls when picked up, won’t settle, avoids the stairs or suddenly guards its bed may be sore rather than stubborn. A new dog can’t tell you it has a bad hip or an upset stomach. It can only show you.

So a vet check early on is always worthwhile, and it’s the first thing I ask about. Your vet looks after your dog’s physical health. My role is different: I spend time looking at the whole dog - how they move, how they respond to people and places, what sets off their worries, and what’s going on in the home around them.

The two work best side by side, which is why behaviour work often begins with a referral from the vet. Treating behaviour without ruling out pain can miss the real problem. Treating the body alone can miss what’s going on emotionally.

Helping a new dog cope with being left alone

One of the kindest things you can do for any new dog is teach them that being alone is safe, starting in the first few days. Begin with just a few moments in another room, then build up gradually, only increasing the time once your dog is relaxed at the current step. Keep your comings and goings low-key.

If your dog panics when left, even briefly, that’s a sign to slow right down and get support. Distress that keeps being repeated tends to get worse, not better.

When to get in contact with a behaviourist

It’s worth getting behaviour support if your new dog is:

• Still not eating or sleeping properly after the first couple of days (please speak to your vet too).

• Hiding, shut down or unable to relax.

• Growling, snapping or guarding food, toys or resting places.

• Panicking when left alone, even for a short time.

• Showing behaviour changes that your vet has checked, or that simply aren’t improving.

Earlier really is better. It’s far easier to help a dog through a wobbly start than to undo habits built on months of worry.

I’m a dog behaviourist based in South Brent and Buckfastleigh, working with owners across the South Hams. If you’ve recently brought a new dog home and something doesn’t feel quite right, please get in contact. Whether it’s a puppy finding its feet or a rescue carrying more than you can see, I’ll help you work out what your dog is trying to tell you - and what to do about it.

Common questions about settling a new dog

How long does it take a rescue dog to settle?

There’s no set timetable, whatever you may have read. Some dogs relax within days, others take months, particularly if they’ve had a difficult past. Go at your dog’s pace. If they seem to be getting more worried rather than less, that’s the point to get help.

Do I need a dog trainer or a dog behaviourist?

If you want to teach your dog skills, a trainer is a great choice. If your dog seems fearful, anxious, reactive or unhappy, or its behaviour has changed for no obvious reason, that’s behaviour work.

Should I see my vet first?

Where behaviour has changed, yes. Pain and illness are common causes and worth ruling out early. I’m always happy to work alongside your vet.

Is my new dog too young, or too old, for behaviour help?

Neither. Puppies benefit enormously from getting the early weeks right, and older dogs are more than capable of learning to feel safe again.
