We have 4 yorkies, one male and 3 females. 2 of the females are spade but the one that isn't, when she goes in heat will start fights with one of my other females, she'll start them over nothing. Sometimes its her getting jealous, other times she could just walk by and the yorkie thats in heat will go after her. Is this normal??? It's been everytime she goes into heat and shes been in heat 3 times. Just concerned.
