I am completely heartbroken and in turmoil. We’ve had our Ddog since he was a puppy, socialised him, trained him, loved him. He was perfect until the teenager stage. When the aggression started. We’ve found lots of ways around it and given him space but this summer he has really escalated. He’s bitten several people, leaving puncture marks that break the skin. He can be so loving and cuddly but he just has this switch that flips into aggression. He’s 3 now and he adores us and we adore him but he bit my 6 year old last night. Dchild just wanted to stroke their dog. Today he’s still growling at our child so they can’t be near each other. I can’t re home him, he would be so upset, he’s completely obsessed with me and adores DH too. If you tell him off he challenges you so we normally move away and give him space. He’s aggressive with his crate (he sleeps in there in our bedroom), he’s aggressive when he gets in the car (he has to go in the car every day for his walk), I can’t give him high value food/treats because he’s aggressive then, he’s frightened of other children. He has to be sedated and muzzled at the vets and still puts up a fight and be pinned down like a wild beast. He growls when you wipe him with a towel, when you hose him off (I used to take him to the bathroom but he became too aggressive to do that), he barely tolerates us getting seeds off his fur. He doesn’t let you brush him, if he hurts himself he won’t let you near him to help him (eg if he has a thorn in his foot). He has been raised in a loving house, he’s not been abused or neglected. He has the most wonderful life. A different off lead walk every day, I’m at home with him all of the time. I socialised him from day 1, followed all of the advice. I don’t know what has gone so wrong. He can be so gorgeous and loving so I feel so much guilt and shame. Everything has just escalated and he’s bitten several times this summer. Getting near him with a muzzle is an ordeal. Yet so many of our friends haven’t seen him like this and would be completely shocked that such a loving dog will be PTS. But others have seen the other side of him and would understand. We know his mum and she’s the most loving dog, which is why we had him but his dad is a working dog so I think his intense personality is from him. He’s a springer spaniel. I am so so sad, we all are 😭 please tell me I’m doing the right thing.
