Adopting a dog from a shelter: Managing common challenges
Updated 17 October 2026
In short: a shelter dog may arrive with fears, anxiety when alone, house-soiling accidents, chewing, lead pulling or a tendency to guard its food. The answer is almost always the same: understand what triggers the behaviour, never punish fear, progress gradually with rewards, and ask the shelter, your vet or a behaviour professional for help if it doesn't improve.
What are the most common challenges?
Storms, fireworks, the vacuum: it trembles, hides or runs.
- Never force it; give it a safe corner.
- Desensitisation: the recorded sound at very low volume, paired with a treat, then increase very gradually.
- Intense fear: talk to your vet.
- Let it approach at its own pace; ask visitors to ignore it at first.
- Meetings with calm dogs, at a distance, on a loose lead.
- Strong reactivity: a trainer who uses positive methods.
Learn to read its calming signals.
Chewing, barking, accidents only while you're out: think separation anxiety. Very short, gradual absences, low-key departures and returns, an enrichment toy. See separation anxiety.
Even a house-trained adult can have accidents in a new place. Start again as with a puppy: frequent trips out, instant reward outside, clean up without scolding, and a vet visit to rule out a medical cause. See house training.
Boredom, anxiety, lack of exercise or a need to chew. More physical and mental activity, approved chews, and treating the cause if it's anxiety. See preventing boredom.
Excitement or lack of training. A Confort Y harness, the Stop and Go method and a reward every time the lead is loose.
A dog that has gone without may guard its resources. Never take its bowl away by force. Walk past at a distance and toss a high-value treat, then move away: it learns that your approach is good news. Growling or biting: get professional help.
Which principles apply in every case?
You should punish it so it stops being scared.
FALSEPunishment increases fear and can lead to aggression. Reward calm moments instead.
Every behaviour has a reason.
TRUENotice when and where it happens: that's the key to choosing the right solution.
It's best to show it everything in the first week.
FALSEThe first days are for decompressing. See the 3-3-3 rule.
What is the shelter's role after adoption?
The shelter knows the dog's past: call it as soon as a question comes up. Many offer follow-up and advice. In a major difficulty, it can offer a temporary solution or, as a last resort, take the dog back. Be honest with it: it will always prefer to find a solution with you.
Which mistakes should you avoid?
Impulse adoption
Assess your lifestyle and budget first.
Unrealistic expectations
Settling in takes weeks, sometimes months.
Too much attention at once
Let it come to you.
Rules that keep changing
The whole household applies the same ones.
Waiting too long
A professional can help more easily early on. See when to call a professional.
Frequently asked questions
My adopted dog is scared of everything, is that normal?
It's common at first. Let it decompress, keep a calm routine and progress very gradually. If the fear is still intense after a few weeks, get advice.
My adopted dog toilets indoors, what should I do?
Restart training as with a puppy, without scolding, and have your vet check for a medical cause.
My dog growls when I approach its bowl, what can I do?
Don't take it away. Pair your approach with something good (a tossed treat) and get help if it's marked.
Can you return an adopted dog to the shelter?
It's often allowed by the contract, as a last resort. Talk to the shelter about your difficulties first: it can help.
