My partner and I have a 5month old cocker pup together (had him since 10 weeks) and whilst we've had private 1-1 training with a trainer + taken loads of vet advice and brought a load of toys/chews/educational toys & take him out for runs in the woods 3x a day, we still have problems with him jumping up/nipping & even biting in some cases when we are at home trying to walk around or do something!
Any advice would be greatly appreciated!
