My beagle puppy is 7 weeks old he has not yet had its vaccination
It looks sleepy all the time and sleeps a lot it breathes rapidly when it is sleeping when it first came home it was alive with energy but now it is very dull everything else about it is fine

Your seven week old puppy is a new baby, essentially. He used up all the energy in excitement when you brought him home. His respiration is rapid because he is absolutely so new to his body. Just let him sleep as much as possible (thats how he is growing). He will gather enough energy again, play, learn, grow a bit, eat and then the whole cycle starts all over again until he is about 6 months. Old. Don't worry, he is a completely new being.
