Thanks guys. I will have them walk along with me when they first meet. He won't be coming over until about when it gets dark, so I may have to wait till my husband gets off work tomorrow before having them both leashed, and in the back yard as I won't be able to see them in the dark tonight.
I am not sure how my dog gets along with other dogs as I haven't had her around too many, though I have never thought her aggressive with other dogs. She plays quite well with our neighbors male dog, and I was watching her yesterday playing with the other neighbors dog through the fence, so I think she's pretty good with other dogs. I have had her for about 9 months, but she has always been around other dogs. My brother's dog is from the same lady I got my dog from, so I know his dog is used to other dogs as well (I wanted her brother so bad but my husband just would not give in!). His dog is not used to kids, but is overall a friendly dog, so I will have my kids somewhat ignore her. I think when my brother leaves, I will put his dog in her kennel for an hour, then rotate them every hour until bed. Their kennels will be side by side with each other. Meal time will be kept seperate along with bowls kept off the ground. Of course all bones/toys will be kept in each kennel and put back with each dog before the other comes out. We will then repeat this when I do not have another adult around.
I guess I am thinking of going very, very slow with them as my thought is to take my time...even a few visits, before expecting them to run and play with each other! They will both be spayed, mine by next month, so hopefully that will improve their chances of becoming good friends!
Thanks for the advice, it's very, very appreciated!
