Can anyone offer any advice, because I am having a hard time at the moment. I have two male Chis from the same litter aged just 5 months. All they do is fight and bark at each other from morning till night except when they are asleep, and when they wake up it starts all over again. I can't give them toys or chews to play with because they kill each other over them. I am seriously thinking of asking the breeder to take them back, which I can't believe because I was really looking forward to having them. but I can't take much more. They are both unneutered at the present. They are not my first chis. I had a little girl for 16 years with on problems. Any advice would be greatly appreciated.
