Many thanks for the help! I ordered the Doxy from the first link and it should be here soon.

I just did not want to put her on one of the other antibiotics if the Doxy was the best choice. I will call my vet up north who just saw this dog recently to see if she might call in a prescription, but in case she won't at least it is ordered and should be here in a couple of days.

S_B, thank you for the recommendation of the Glyco Flex III. I had 2 big bottles of that and it does seem to help. I am out now and switched back to the Liquid Health 5000 last week. I have used both and they both seem to work about equally well.
