Bonnie, I was very concerned about Rupert getting along with another dog. Although he was missing Riley so much and not enjoying being the only dog, he has territorial aggression issues with other new dogs in his 'hood. He was very stresssed and unhappy in the weeks after Riley died and I was scared of how he would react when we went to meet Jemma, as he does not behave well towards younger dogs. I told the breeder this and she told me she knew what to do.
Instead of Rupert meeting Jem right away, Betty put Rupert in her fenced-in backyard with two of her adult female Corgis who she knew could take care of themselves and wouldn't put up with any guff from him. You could see from his face he was out-smarted and he was quite well behaved. After about 20 minutes with them, she brought out Jemma and her mother. By then he knew that the Corgi girls were boss and he was fine. He gave Jem a wuff to tell her what he thought and she just turned right around and wuffed him back.

Other than two incidents - over food, he has been great. I treat him as the alpha so he know's he's still number one and doesn't feel threatened by her being here. They play every day and he even lets her snuggle up against him in bed now.

So talk to the breeder about how to treat them both and I think you'll be fine.
