Willy has been losing weight lately and drinking a lot of water. We took him to the vet yesterday figuring diabetes. But, his urine sample is definite for kidney failure.

He's only 6 years old! Willow, is sister, is healthy as a horse.
We started them on k/d wet and dry food. Luckily, everyone seems to like the wet food. Willy loves the dry food more than the wet.

If you have any experience or advice, please let me know. Our vet does not seem hopeful for his long term health.
