I am so sorry to hear that Becca is having another attack. I hope the meds work quickly and the clinic can find exactly the cause and find a treatment.
Max had Lyme and other than showing a mild positive to blood tests even after treatment he had no other problems. Tho I have often wondered if it didn't some affect on him with the IVDD in his neck, the DM and the lymphnoma.
I know there is a type of arthritis for humans so it stands to reason it would affect dogs also. I don't like the Nexguard or any of the other oral stuff for fleas and ticks. I have not heard good things about them in the reviews.
Continued prayers that they can find a solution to her flare ups and something to help if she does have arthritis. Ask about acupuncture if it would help the arthritis discomfort. I saw what it did for Max and his neck. Because dogs don't know any better when you see a drastic improvement you know it's working. I now use it for back pain, arthritis and neuropathy in my feet from spinal surgery. I never would have tried it if it hadn't been for Max.
