I have several Yorkies at home and we all live under the same roof. Recently my 5 month old female and 5 month old male have started fighting. They get along great then if we take one out of the house and come back it's fight time or if we are giving treats its fight time. Most of the time my 4 month old tiny female likes to instigate it when the two 5 month olds are playing then it turns into a big fight between just them two. They are fine with all of my other Yorkies. None of them are fixed and I do not plan of fixing them. I'm just wondering if anyone has experienced this before. They are not from the same litter and we got them maybe a month apart from each other. The male is the bigger one and we got him after the female, but the female it the one that starts all of the fights with him. Any information is greatly appreciated.
