Don't give up!
Have a look at the other feed on 'manic puppy nipping' - our puppy George sounds like he's only slightly older than yours and he was mental until very recently - I really think it is a phase they just have to get through!
He bit sooo much we had cuts and scratches and tears in our clothes everywhere!!! we were at the end of our tether and it just wasn't enjoyable having him round! - and when I say not enjoyable I mean actual pain a lot of the time!
But this last month he has calmed down soooooo much! sooo many more of thos elovely moments and almost no manic biting moments
also he got worse before he got better so you could be on the verge of cracking it!!!!
Things that really helped us were:
- ignoring him when we first come into contact with him - even if we just left the room for 2 mins we would ignore him when we first saw him again - he would go mental & bite for attention for the first few mins then when he finally left it alone and went off to settle (sulk!) somewhere we called him over by his name and stroked his head and neck area - he just melts on the floor and goes super submissive if you've left it long enough - this really seemed to show him who was boss like nothing else and set him up on the right tone for the rest of the evening!
Not amiracle and we still had manic puppy moments - but much less frequency and we seemed to gain more control....
mid puppy moment?
we had to resort to grabbing him by the scruff and plonking him in his crate for a 10 min time out till he calmed down! (I know alot of people will disagree with this method but it was the only thing we could do)
anyway - the other post was more expansive but I really wanted to give you some encouragement because I know how you feel! and I think we're just a small amount of time ahead of you so I'm sure you'll crack it soon!
let me know how it goes!
