Just wanted to comment that recent research has shown that though rare some vaccines can cause many abnormalities such as thrombocytopenia that can last for up to 2 years (requiring treatment) until finally resolving! So please don't be discouraged!
Of course there are other causes beside vaccinosis for thrombocytopenia and anemia.
How is you boxer since your last posting? Have you found out the casue of the low platelet count? My boxer has the same symptoms and the vet seems puzzled. My boxer is going to see a specialist on Monday. Since we have lowered the dose to 1/2 of 20 mg pred a day he is coming back around. Before he was lethargic, loss of energy, could harly walk on his back legs. Platelet count went from 12,000 to 4,000 in about 3 weeks after being on the prednisone and after having his yearly exam & vaccines. After reading Dr Chengs response for your boxer, I wonder if this could a result from his vaccine. The specialist will do a ultra sound & a bone morrow test since we did have a mass cell tumor removed from his side in July 07. Platelet count at that time was 27,000. He is now taking doxycycline.Tick titer test was done in July 07 & results were negative. We are now waiting on the Tick titer test that was done this week. We adopted him in Dec 06 and I do have the previous records from his previous vet. He had same issues in Oct 05 and tick tests were done, prednisone, doxycycline & vitimin K were all prescribed at that time for possible rat poison & tick bites. To my knowlege all that was negative. Until the yearly exam & prednisone he was VERY active! Any results you received may help resolve my boxers issues. Hope to hear how your boxer is doing.
High does of prednisone can cause joint, tendon and ligament damage but only if at very high does for a very extended period of time, and I don't believe he has been on them long enough for this to occur. If his platelet count and behavior were under control when on 2 tablets of prednisone twice daily than I hope he will be able to decease from the 3 tablets he is currently on back to the 2 tablets soon. He will have to remain on the 2 tabs of prednisone twice daily for a while, and your vet will monitor his bloodwork frequently.
Your vet sounds like he is doing a great job. As far as alternative medicine is concerned I feel that it certainly won't hurt and may help. Since this is such a complicated problem it is best to find a holistic vet in your area. Please check online at: the American Holistic Veterinary Medical Association website, or the Chi Institute of Veterinary Medicine and Acupuncture, and IVAS (International Veterinary Acupuncture Society). I can only speculate without actually examining your dog personally what herbs or alternative medicine to give. If I were to speculate from what you have listed I would say that your dog has a bout (among other problems) of Kidney Yang Deficiency. Kidney Yang deficient dogs commonly have hind limb weakness, and I would try to strenghen your dog with kidney yang tonics and acupuncture. It is really best to have your dog seen by a holistic yet. If you have trouble finding a holistic vet in your area please post for area or city and state and I will be glad to find one for you. Please keep us posted!
