Hi sorry this may be a long one. We have a 12m lab, he's not our first dog and we did lots of research before choosing him. We started straining at 10 weeks and enrolled in puppy classes at 4m. We were seeing progress but it all went to pot around 5/6m. It doesn't help he's a big dog. (Around 45kg now) the issues are -
Jumping up (mainly at others) - we ignore this which works mostly but doesn't help with other people
Biting - never improved now uses it to show annoyance ie on way home from walk or if taking away something he shouldn't have
Pulling on lead - this started about 5m we stop and make him walk back. He does it then immediately starts to pull again. I tried the change direction but he pulled then too. We do heel work during walk he can doit but on his terms he will move away if had enough. Treats he will accept then move immediately after.
Recall- he's great unless he sees another dog. He is fine with other dogs but other owners don't like him as he's so big and boisterous
Jumping up when we are eating/busy- we try to get him to sit and reward but he just comes back. Treats he gobbles down, chews/toys he ignores.
Biting lead- if we use it in house ie if visitors are there or at other peoples houses he will go mad and bite/pull lead. Also does it on way home from walk we try to ignore it/not engage
We just don't know what to do. The puppy classes were reward based and worked to a point. When we tried to reduce treats he stopped responding as well and now he will follow commands for treats if he wants to he's not that bothered. We got a second trainer at 10m she told us to shake a bottle at him or spray water in his face. We tried the bottle, he became aggressive so we stopped and didn't go back. We have had two sessions with a new trainer who teaches through play he's enjoying it but if I try to add commands in sit, wait etc he sometimes does it or just ignores me. It feels like a constant battle of wills. I find it frustrating because I spend hours everyday walking/training/ playing with him for little or no reward. He's not affectionate or cuddly and doesn't give back.
I'm sorry it's so long just wondering if anyone has any ideas that worked for them or people who had similar experience and it got better or is anyone struggling like me? Thanks
