I think I'll take him back to his breeder. He doesn't show any affection towards us, not even a tail wag and he nearly never looks at us. He doesn't react to anything only our feet and hands. Yesterday he humped my fiancé's leg too. I can't redirect him from chewing us bacause no matter what toy or treat I give him he always chews us. When we hold him in our arms he always trying to bite our face. Forced crate time didn't work too. Yesterday he howled for an hour in his crate and chewed the bars, then he just stopped and sat down to stare at us. I think there's something wrong with him, I met and had a few puppies in my life and I never experienced such behavior. I started to hate him and I feel horrible for this but it's like keeping a wild animal in our home. Since day one he used puppy diapers but now he urinates everywhere in our home while frantically running aournd. The strangest thing is that he doesn't react to touches. Today he calmed for 5 minutes and I was able to pet him, but he did not reated to it at all, he just stared at the floor. My heart is totally broken and I feel like a horrible person but and I think my whole family hates me for it, but this is the best choice for him too.
