Blitz is 2 years and has never been a picky eater. I usually feed him at 9pm but went out early at 5pm to feed him but he just walked away from the dish. He normally is very hyper but looks depressed. We went on our walk today but he acted normal while out. He is drinking water. I must add last year in September he lost his dad and never was the same again. I feed him the raw diet and has all his vaccines

Try again at 9. Dogs do like to keep to a schedule just as people do. Four hours early he may simply not be hungry.

Please give him some time. I've never know a dog to starve itself. You might try changing his food. If he still doesn't eat in a week, then please call a vet, and go see them. Good luck.

A dog going a week without eating is very dangerous, do not wait a week. Two days without food and I'd be in the car already

Did he eat at 9?

A week without eating? Foolish advice.

Any out of the ordinary behavior needs to be reported to the Veterinarian. Food aside, dogs dehydrate very, very quickly.
