[susan lynn]

I have 4 Yorkies, I got Tessie first, she is now 2 years old, I got 2 males after her they are 2 and 18 months now. I brought in another female 6 months ago. My other dogs hated her, (she has the same parents as my 2 male dogs). I had to be with her at all times when she was with them. Her name is Sassy, even though she was a puppy she would attack Tessie and bite on her constantly.Tessie would not fight back.I started putting Sassy in the laundry room in timeout when she did this. I almost took Sassy back to the breeder because I was afraid the dogs would never like her. Sassy will take Calvin by his collar and drag him around on the hardwood floors but she is only playing. I know your pups are very young ,you will just have to only let them be together when they are supervised. It will take time but they will eventually come to love each other. You always have to keep Milo first and make sure he knows he is loved and not being replaced. All of my dogs are spayed/neutered and this also helps.
