Hi, Thanks so much for the link to that great article Donna.
I wanted to give an update on what's happening with my girl, Jenna. I have been doing my best to restrict her activity (so hard and confusing for her) and did take her to see the vet early this week. My experience as a human physiologist really had me leaning towards muscular injury and even iliopsoas or groin type soft tissue injury but I didn't want to take any chances with a cruciate problem and have it get worse. So, the good news is that my vet did not find any definitive signs of cruciate rupture (drawer test was negative) although she didn't feel that we can completely rule out a partial tear. She seemed to think that soft tissue injury was more likely and of course, more difficult to pinpoint. I mentioned that I was thinking psoas muscle or even IT band type issue and she was willing to agree that it seemed possible. We decided on (the dreaded) severely limited activity and NSAID- Metecam_ for 2 weeks and see how that goes. After 3 days of the meds and limiting her she does seem to be improving. The intermittent lameness is still around but seems less severe and some of the behaviors that I would have attributed to her being uncomfortable or painful have improved. So, it seems that this is a good strategy at this point....
I have wondered if the combination of hardwood floors and a best friend/playmate that is a mini dachshund have contributed to a lot of wear and tear on her hips and lumbar muscles. Jenna is also a frisbee and agility addict and I hope that this doesn't become an ongoing problem of muscle/joint inflammation. I am beginning to research different exercises/therapy that may be advantageous for her.
Thanks again for the input,
Angel
