I will say that I've never had any issues with a dog not being the same by using berenil. I've used the zithromax/mepron treatment on a few dogs, and there was no difference in the dogs after that treatment or the dogs treated with the berenil/doxycycline protocol that Dr. B has come up with.

I've seen the Berenil/Doxy treatment work successfully on a dog that became sick the last 3 weeks of a keep. Following Dr. B's treatment plan, the dog was able to still work through the sickness, recover from it, and prevail in his outing.
