My German Shepherd Walter has polyarthritis which is very painful for him. The medication that he takes is very expensive but is the best possible option for him. Other medications that he could take would have serious side effects. Without pets best I would not be able to provide Walter with the best possible care. I am so thankful that I I am with pets best. I have pets best for all of my dogs and always recommend to my friends and family and fellow animal lovers that they get pets best as well."
