I have read a lot of posts here and a couple of things I would like to express. LO doesn't bark he yips. Is this normal? He has only frapped once. He seems to be able to jump really high. He looks a bit lean compared to other pics of the puppies. He is 20 weeks today however the vet seems to think he may be a couple of weeks older based on adult tooth eruption. He has been lifting his leg to pee for at least 6 weeks now (not consistently). Ok I need my peeps on here to reasure that he is normal.
