My Dandelion is 11.4 years old and just started to have trouble with his back leg. I took him to the vet and he has been on Gabapentin for about a week. Has anyone had any experience with this medication for their rabbits arthritis? I read on MediRabbit.com that it sometimes leads to serious side-effects, when used for a long period of time. Does anyone know of anything better, besides Metacam? Do steroid shots help? Thanks so much for any help anyone can provide.
