Hi, so finally got our puppy and he's fab, pretty much housetrained after a few days, has already learnt sit, down and we're practising walking on the lead indoors and in the garden until he can go out (he's 9 weeks), loves meeting people, takes everything in his stride and we all love him to bits...just that every night he turns into some sort of Cujo! He goes mental, jumps up, nips, won't listen to anything, grabs DDs clothing, hair and will not let go, they do all the right things, ie stand still, yelp, tell him no, he's v aggressive and growls, I've growled back at him which sometimes stops him but nothing seems to calm him down. I realise he's probably overtired but he does sleep a lot in the day and on the whole is really gentle and fine then, around 7 each night turns into a monster! I know it's normal puppy behaviour and am not worried he'll grow up to be aggressive or anything but how do we calm him down? I don't want to put him in his crate as that feels like punishment, he goes in it great at night and sometimes take himself off during the day but mostly likes to sleep on the towel by the back door (think he gets hot), he'll go in it when we have to leave him but soon I'll be at work again and he'll be left for 2.5 hours at a time twice a week so don't want to give him negative associations by shoving him in when he's not behaving how we want him to! Have tried ignoring him but he then starts chewing and grabbing at anything he can, I have tried putting his lead on and training him to focus him, I know it's all normal but any ideas on what we can do to give him a time out without crating? He loves the garden but when he's out there in this mood he chews moss, grass, tries to eat cat poo, just totally goes wild! Think he sees DDs s playmates or food at this time and mauls them! Apart from this he's great!!
