I have been working with my dog a bit, and I have noticed he has started to skip meals. When you are working your dogs, do you notice they don't eat as much? I have had food spoil on me before, but I am not sure if this is the issue, or just the fact that he is working more. He will eat the food, and has never been a ravenous eater, and sometimes would only eat once a day, even though offered 2x a day. Yet I have noticed He is not eating the whole day. Acts fine, not acting sick, any thoughts?
