My dog is sleeping with me in my room is an American pitbull 3 months old he went to bed and I c him with a big smile but in a way trying to breath quick is it because is too hot or is nothing bad? What should I do?(my first dog in my whole life)

Heading says heart beat, description says breathing. What is it?

Wen I touch his heart it beats very fast but at the same time it sounds like he gasping for air

It is hard for anyone to tell you if this is normal or not. If you are really concerned, than you should speak with your vet. Besides.. its time for vaccines anyway!

Because of their facial features, many bulldogs have a tendency to breath in a gaspy manner. Heartbeat in young dogs tends to be faster.
