Zulu has been diagnosed with arthritis in his left hip. I noticed a few weeks ago that he was having trouble getting comfortable when laying down. He used to spend most of the day laying on the floor next to me while I worked. He started spending more time on the couch, so I put one of his beds in my office, and he would lay on that. Several mornings ago, he had a noticeable limp getting out of his bed. After he moved around a bit, he seemed to loosen up. The limp was mostly noticed after he had laid down for some time. Took him to the animal hospital, the vet worked his joints, Zulu did not react negatively to any of the tests. But the x-rays revealed a slight gap in his left hip. Vet says it is in early stage, so we should be able to manage it with drug therapy, exercise, and losing a few pounds (he is 28 lbs.). She prescribed 25mg Carprofen, and gave him an injection of Adequan. He will get 4 weekly injections, then monthly for 6 months. Three days have passed since the first injection, and have not noticed any limping. He had a good walk this morning, and is currently outside barking his head off at our neighbor repairing his fence. Hopefully, by catching it early, we will be able to slow the progression, and he can enjoy his senior years.
