Leevalle, I wouldn't think there would be a lot of complications, given that she is 95 pounds. She's a big girl! However, you should take her to the vet and have her checked, because there can be complications no matter the breed (even in mutts). Is she a show dog/breeder? If she isn't, I would seriously recommend having her spayed. It's generally frowned upon by the "dog society" to allow a dog of any breed to become pregnant - if they are not show/breed quality. Many would be pet owners are not responsible and do not understand that just because they saw a dog on tv performing tricks, doesn't mean that theirs will. They don't put in the effort to train and then become frustrated when the dog chews their shoes, electronics and even worse, their house. They take the dog to the shelter out of anger and then the dog gets put down. It's not fair to anyone, especially the dog. /soapbox
Sorry I wasn't more help than that. Good luck, though.
