As a puppy and young adult the pug can be a real handfull! They hardly ever sleep and are much more active than what's normal with other breeds. Bajas used to drive me insane when he was a puppy - when he finally fell asleep I did't have the heart to move at all...

The adult pug is a quiet, well behaved (usually :)) pet. Their small size and good temprament make them an ideal comcpanion and a great friend you can bring anywhere. However you need to give your pug proper excercise. They are prone to overweight and you need to watch their treats/food as well. Their short face put a certain stress on their breathing, and excess weight will encrease that problem. You also need to prevent them from overheating, which they are prone to. Very cold air will have virtually no time to warm up before hitting their lungs, so no long walks when it's terribly cold either. Your pug will manage to show you what's too cold! They have a nice, thick coat and don't really need a coat. But they might look very cute in one.... :)

Their squished in face and curly tail make them difficult to read for some dogs, so you need to watch out to make sure they don't get in trouble. A pug will rarely start the fight, but if the other dog feel threatened by the pugs appearance you risk giving your pug a bad experience. Generally pugs have excellent language, however, so with most dogs (with a good understanding of the doggy language) you'll have no problems.

The pug will generally be a one-person-dog. They love every human(and dog, and cat, and...) they encounter, but there is only one they adore. They have great food-drive, but you might do well to try to find aditional sources of motivation.

The pug is not for everybody. They need companionship and activities to thrive - but for the right person they make a WONDERFULL pet!
