Pet Behavior Problems: Why They Happen and How to Fix Them
Almost every behaviour problem is a normal animal behaviour happening in an inconvenient place, a symptom of stress, or a sign of pain. Working out which one you have is most of the fix.
Rule out pain and illness first
A sudden change in behaviour in a previously settled pet is a health question until proven otherwise. House-training that falls apart, new aggression when touched, a cat missing the litter box, a dog who stops wanting walks — all of these have common medical causes. Book the vet before you book the trainer.
Barking, chewing, and jumping up
- Barking: identify the trigger. Alert barking at the window is managed with a film on the glass; boredom barking needs sniffing walks and food puzzles, not a louder 'quiet'.
- Chewing: give legal outlets and rotate them, manage the environment while the dog is young, and increase mental work — most destructive chewing is an under-occupied dog, not spite.
- Jumping up: it is a greeting that has always worked. Turn away and give zero attention for four paws off the floor, then reward the sit. Everyone in the house must do the same.
- Digging and counter-surfing: manage access, then make the alternative more rewarding than the habit.
Cats: scratching and litter box misses
- Furniture scratching means the scratching options are wrong or in the wrong place — put a tall sturdy post right next to the spot being used, then move it slowly.
- Litter box misses: after a vet check, add a box, try a different unscented litter, uncover it, and move it away from noise and food.
- Spraying on vertical surfaces is usually stress or another cat, indoors or outside. Clean with an enzymatic cleaner and reduce the trigger — never punish.
- Night-time yowling in older cats deserves a vet visit; it is often thyroid, blood pressure, or cognitive change.
Distress when left alone
Vocalising, destruction near exits, or accidents that only happen when nobody is home is a panic response, not disobedience, and it rarely improves by ignoring it. Film a short absence to confirm, keep departures completely undramatic, and rebuild alone time in seconds rather than hours. This is one to get professional help with early — it responds far better to a structured plan, sometimes alongside medication from your vet.
The rules that apply to everything
- Reward the behaviour you want more often than you interrupt the one you don't.
- Manage the environment so rehearsal of the problem stops while you train the alternative.
- Change one thing at a time and give it two weeks before judging it.
- Never use punishment for fear-based behaviour — it reliably makes it worse.
- Get everyone in the household saying and doing the same thing.
Vet check first, then manage the environment and reward the alternative — and treat fear or separation distress as a job for a professional, not more discipline.
