Why is my dog growling at food bowls and not eating after moving?

Hello, and thank you for your question. I'm sorry to hear Toby has not been feeling well. It sounds like he may be stressed from the recent move. Some suggestions and thoughts:
1) Ensure he has some comfort items in the new home that is used to, e.g. his old dog bed, toys, etc. Even better would be a crate that he usually sleeps in. Any of these items will provide some comfort and familiarity in his new home.
2) When he doesn't eat or drink unless you hold the bowl, that may be his way of getting attention from you. Has your work schedule changed so you are spending less time with him on a daily basis?
3) There is a dog pheromone spray called Adaptil that can help reduce stress in dogs during times of change. This can be found readily at most vet hospitals.
4) It is also possible there may be a medical issue going on. If we have ruled out behavioural causes, it would be worth visiting your vet in order to rule out any sources of pain or discomfort that may be causing him to avoid his food and water.

I hope this helps, and that Toby is feeling better soon!
