If a dog eats a lot of raisins, the dog's kidneys get a double-whammy. First the kidneys are overwhelmed trying to rid the body of the sugar. In order to do that a lot of water is pulled out with it-- oliguria is the symptom. At the same time, the raisins (which are almost all sugar) are putting an osmotic load on the animal. Instead of water from the intestines being absorbed back into the body, the sugar concentrate sucks water out of the body into the intestines. When there is no longer enough water in the bloodstream to allow the kidneys to get rid of the sugar, the kidneys shut down (anuria). The final blow comes from the sugar that keeps on entering the bloodstream. This dosn't affect humans in the same way because people get sick of raisins long before it got to a lethal amount. Sugar is not good for dogs. Their natural diet is meat, and even though they can eat other things, pure sugar is not something dogs (or humans) were built for.

If a dog eats a lot of raisins, the dog’s kidneys get a double-whammy. First the kidneys are overwhelmed trying to rid the body of the sugar. In order to do that a lot of water is pulled out with it– oliguria is the symptom. At the same time, the raisins (which are almost all sugar) are putting an osmotic load on the animal. Instead of water from the intestines being absorbed back into the body, the sugar concentrate sucks water out of the body into the intestines. When there is no longer enough water in the bloodstream to allow the kidneys to get rid of the sugar, the kidneys shut down (anuria). The final blow comes from the sugar that keeps on entering the bloodstream.

This dosn’t affect humans in the same way because people get sick of raisins long before it got to a lethal amount.

Sugar is not good for dogs. Their natural diet is meat, and even though they can eat other things, pure sugar is not something dogs (or humans) were built for.
