I have a 2month old cattle dog puppy. I want to start the training early to keep from having to undo the bad habits later. First what should we do about the biting (it is done when he plays) Currently when he does this I hold his mussel lightly and say "no biting" then try to redirect him to the chew toy. This works sometimes. Sometimes I try to play with him with the fussy chew animal thing. Is it ok to pretend growl and shake his head gentle back and forth like a tug of war? Or will that encourage more aggressive play? Sometimes I think he is sleepy and put him in his crate where he sleeps and where I keep his raw hide thing. Are these appropriate methods? We got him Monday so I do not have a lot of reading done yet? Here is a picture I just took. They are not very good and I know that we can get better later.
