I was walking Sunny today, its his 5/6th time. We went into the backyard, and the neighbor's dog came barking. Sunny just want crazy, hissing, growling and slashing. I had to pick him up and take him away, and the dog's owner took the dog away too. I don't think Sunny or the dog were hurt, but I got a couple scratches... Didn't know cats were capable of that. The dog would have been beat up if I hadn't intervened. How can I train him not to go crazy everytime a dog walks by?
