I have an 11 month old English Cocker Spaniel that we have had since the age of 7 weeks. Recently he has been aggressive on 3 occasions and we fear it may be Cocker Rage Syndrome. He seems unaware of what is happening and his face changes completely. His eyes seem glazed and he growls snarls and barks at whoever is nearest. It usually happens when he has something he shouldn't i.e on one occasion he had a sock and had backed under the table so we couldnt reach him. When my partner put his hand under to pull him out he went. Another time he had got something out of the bin and went for me when I tried to take it away. He also went for me when my son had allowed him on his bed and i tried to get him down. We are normally strict with him and dont allow him upstairs or on the furniture. Stan is normally a lovely happy dog and very much loved by all the family. We have children and Im afraid he will do it to them or one of their friends and then something bad would happen. Can anyone help us please!!!!!
