My cocker spaniels have been eating grapes since they were pups, [ they think whatever I eat they're supposed to too] my cocker is going on 16 years, then my angel was 12 years when she passed, her mate rounder is 7 years, and they're daughter which is my oldest's great grandaughter darling, will be 3 this halloween ] Not to doubt your vet, It could have something to do with the size of dog, but I have a hard time believing what your vet told you. Not to sound cruel, but vets are just ordinary people who lay blame on anything but themselves. And all that I know of Vets is they are greedy and want your dollars. And I have had furry companions and feathered companions all my life, and I have yet to find a vet with a lick of common sense. Its like my Dad used to say and he had a brother who matched this stereo-type, the more book learning they have the less common sense, of the majority of people. My opinion is only a opinion, take it with a grain of salt, but vets are not all powerful, and they don't know everything.
