All Hi. It's been a while since I have posted here. Hope all is going well. Anyway, I have a question that I hope you can help me with. I have a BC who is very atheletic and driven. He loves to play frisbee and fetch with a ball. However, he goes at it like a demon...full speed ahead all the time. Anyway, about a month ago, I noticed he was slow to rise after physical activity. I physically handled his leg, looking for any sign of pain from the dog, but he never showedany. Anyway, after one play session, he was very slow to rise, so I went to the vet. By the time we got to the vet (next day), you couldn't tell anything was wrong. The vet thought that it must just be muscle strain after checking out his leg. So, for the next 2 weeks, no play sessions, just walking. He seemed to be ok with no signs of the lameness. So I started playing with him again, but in amore controlled way. The lamess reappeared, but was very minor. This past Saturday, I went on a 3-5 mile walk with the dog. No running, just walking. That afternoon, he could barely get up. I have a vet appointement todya, but I was hoping someone could give me their thoughts on what is wrong. In searching the web, I have 2 thoughs. A partially torn tendon or hip dysplasia. I was hoping it was muscle strain, but I'm not so sure anymore. My thoughts on the hip dysplasia is that he had not shown any signs of lameness prior to about a month ago, so I hope that's not it. My BC is fit, weighs about 45 lbs and is 2 years, 3 months. Thanks in advance.
