okay i got my english pointer pup a few days ago. and he is 7 weeks old. i think he is small for his age cause i ran into a girl w/ a 7 week old setter and it was double the size of my pup. well he does some weird things. like when he eats he like crys when he is eating, is that normal? also i know puppies chew and play bite but he seems to take it to a whole new level. he will grawl and bite me and not like wagging his tail and playing ,to me it seems like its not really play..is that normal?? i have a toy rope and a tennis ball and i have a pig ear for him to play and chew but he would rather bite me.. though he does love the pig ear.. so im wondering if something is wrong w/ him or am i just being a new parent and am just thinking that.. thank you if you can help
