I have got the litter brother and sister richy 3 month old pups. The dog will not listen to us, if I try to get him to do something he just runs under the chair, I've tried to get him out but he just growls and has tried to bite me. On the lead he will not walk proper, bites the lead. His sister has started to pick up his bad habits. When he has been naughty he has been smacked with 2 pages of paper rolled up so I know it does not hurt him. I also have put him in his crate but he just barks and howls. We are at a loss what to do.
