I'm seeking desperate advice hopefully from experienced dog owners. We have a golden show cocker spaniel that we bought from a one off family breeder. When he who as a puppy we did have agression / posession issues with him but thought he would grow out of it. Over the 4 years we have had him he has been incredibly terratorial, going for anyone who comes into our house that he doesnt know. We paid 400£ to get a behaviourist lifetime support contract. She did show is techniques which help us to manage him but we are still on edge with him. We have a little boy 2.5 now and he adores the dog, Oscar and vice versa. There have been various incidents where Oscar has attacked without been provoked, about 3 weeks ago he bit my brother he has also bitten another family member. Things were doing ok up until the weekend where my OH was stroking him on the sofa and I watched the change, his eyes glazed over and he just went into attack. My OH managed to defend himself and Oscar ran in his bed. We shut the gate on the kitchen but he continued to lunge and attack us both, I dread to think if the gate wasnt there! The following morning it was like nothing had hapened. Again, Tue night exactly the same he attacked us both but wed morning he was fine for 5 minutes and then went for me. I couldnt go in the kitchen all day. We last night made the agonising decision that he has to go, we have booked him in at the vets to get him checked over but after that we are hoping to take him to the dogs trust. 95% of the time he is the perfect dog, and we adore him but we can no longer take the risk with having a boistrous toddler. Please tell me Im doing the right thing? has anyone ever experienced this? Experiences of rehoming an aggressive dog? I absolutely am heartbroken and have cried all night and day. If there was anyother way I would do it. Thanyou in advance for any replies, and Im sorry for the long rambling desperate post. Heartbroken Carly x
