HEY! i am a first time poster here. I recently got a golden retriever puppy (adopted) from a friend of mine. he is 38 days old. He sleeps almost whole day, so at what age will he become more active? And one more question, he sneezes and some liquid comes out with his sneeze like it does with us humans sometimes but he refuses to sleep on a bed or blanket or anything and goes to sleep on bare floor so is it possible that he has cold? I went to his vet but this problem started after visiting the vet. He runs and even barks sometimes while sleeping. So all this is normal for a golden puppy this small or should I do something about it? Anyone experienced can help me here I am scared to death about all these...
