Training & behavior

The **Training and behaviour** section helps you understand your pet and build good habits together. It covers basic dog training, potty training puppies, dealing with cats peeing outside the litter box, and decoding how dogs and cats show their feelings through eyes, tail, sounds and body posture. The guiding principle is **patience, consistency and rewards**. Instead of scolding or punishing, praise and reward your pet when they get it right, keep sessions short and daily, and keep the same rules across the household. A sudden change in behaviour, such as toileting in the wrong place after being well trained, can sometimes be a health sign, so consider a vet visit. Good training also keeps pets safer: a dog that comes back when called and is used to wearing a collar is less likely to get lost.
