Hi MajesticCollies,

You're right...Our vet told us that it has something to do with the immune system. Since my dog's still a pup her immune system might not be that strong.

I am going back to the vet with her in a few days and I will ask the vet more about it.

Just curious, what kind of vitamin C do you give her?

By the way, based on the pix I think its the same as the one that was on Snapples a week ago...

Thanks,

Ellen
