The Anipryl seems on the expensive side from the vet but you can buy it on-line at places like 1-800-petmeds for fairly inexpensively - or talk to the vet about the cost. When I ordered Previcox thru 1-800-petmeds one time my vet knocked his cost to me down to what 1-800-petmeds was charging. I figured the dog issue with your Mom was something to do with your parents relationship but see if, for the dogs sake, you can get her to talk to the vet about meds. Emphasize to your Mom that she is the one who makes any decision - not the vet and she can make clear she is just there to talk about medication. The supplement that you are giving the dog may not be enough if her hips and arthritis are bad. When I started the Previcox for my girl it was like I had my young dog back. Even if your parents cannot afford expensive medication, vets these days are even prescribing asprin (dose has to be low - like a baby asprin) for dogs to help with pain. Only way to know is to get you Mom to take him to the vet. The other thing I can say is I have many friends who are not "animal people" and they often "suggest" my life could be easier without my girl. It makes me nuts and angry when they say that and I do not find it helpful - having a little bit of support and understanding is what makes my life easier. So maybe with your Mom - instead of arguing with her just try and do what you can to help her or at least let her know you are trying to understand her position and work from there. Offer to go to the vet with her. Good luck.
