I have 4 yorkies, they are close in age, Tessie is 2 1/2, Hobbes is 6 weeks younger, Calvin will be 2 in Sept. and Sassy will be 1 in August. The first 3 did great together, I just made sure I didn't give more attention to the new puppy. I never left them alone until I knew they were ok. The first 3 did great together. But when I brought Sassy home I was afraid they were going to hurt her,they were so aggressive towards her. I never left her with the other dogs. I think it was because she was a female. It took a while but now they get along good. Actually she thinks she is the boss. |
