It could be a side effect from the medicine. Years ago my beagle was taking an antibiotic for an infection and he was walking funny like he couldn't stand up. We looked up the medicine in a prescription book and that was one of the side effects-weakness of the extremities. So I took him back to the vet along with the book and showed it to the vet and they changed his medicine. See if you can look up the side effects of the antibiotic and see if it's a side effect. Good Luck!! |
