When do pups stop having a witching hour where they bark, bite and jump? Mine is 5 months old now and we do loads to wear him out but also plenty of naps. I've never managed to enforce a nap. I'm trying to get the family to ignore the barking and nipping as he does give up eventually but trying to get them to be consistent is almost impossible!
My other question is why do they get bored of chews? He likes certain chew but I have packs of 5 and he loses interest!! Should I put them all away so they have more novelty value? I have tried that but still no interest!!
