Grizzy eating a bit again

Grizzy is eating his rice and browned ground beef again.  After not eating on Thursday I called the vet and it was suggested to try adding beef bullion cube water over his food.  He ate Friday evening and even this morning meal - it was raining he often doesn't eat when it is raining (strange dog - I would understand not eating in thunder - he is afraid of thunder but just rain).  He ate a bit more tonight too without prompting using the bullion water over rice and beef.  Still haven't witnessed a movement but he seems to be a bit more chipper now that he is eating.
