Wow so much has happened the last few days, I hardly know where to start. We noticed Matilda seemed to be favoring her right back leg, when I would go to take her on walks she would go out and do her duty, then she would turn and head for the RV. Not like her at all. Usually on our walks she is so busy meeting people and sniffing other dogs. Yesterday she would not even use her leg, so we went to see a vet that we use while in Yuma, the vet checked her right back leg and said it seemed ok, then he ask us if we thought it had gotten worse, we told him we had noticed that it had. He suggested x'rays, he said he would have to put her under so he would also pull the two baby teeth that had not fallen out, so she spent most of the day there. It drove me crazy not having her with me. We went to pick her up and look at the x"rays, the doctor told us she has Perthes Disease in her hip area. He said it had gotten pretty bad fast, and he felt like she should have surgery. Talk about surprising us, I wanted to cry as her explained the whole thing to us. My husband ask when she could have surgery, and the vet said tomorrow. I feel like I am in a bad dream, I don't want her to suffer. but I can't believe this has happened. Have any of you heard of Perthes Disease? I hope someone can give me some advise. I feel like crying.
