My Akita usually loves his food, but the past few days he has just turned up his nose at it. Should I worry? I always have chosen meat with gravy as he loves it. He dislikes the ones in jelly! He has dried biscuits in a dish by his water dish all day and they are hardly touched either. It seems rather trivial to take him to the vets for not eating. He seems okay in himself in every other respect. Any advice please.
