How old is he now? Looks about 3.5 months?
I wanted to buy his dad at first, but that dog likes to bite so much that even bites his own handler, (training) and something strange about him is that he goes for real, that means doesn´t go for the sleeve, but tries to nail the flesh instead haha. His mom is a frigging arrow, flies and everything when attacking. This puppy is exactly 3 aznd a half months, you have a good eye.
