Cobi attacks food like he hasn't eaten in years. However, there are HOT days that he isn't as rambuncious, rather like we are when it's hot. We just don't want to eat. Holding out for treats is a good answer to the problem too....maybe use carrots or beans for a treat instead of something else...and only for special times. As I've said before, our vet told us that dogs, especially beagles, will never starve themselves to death, if food is available. I'm thinking it's a matter of mind over matter, she might just be trying to psych you out.
