I've got an amazing 8 month old Goldendoodle who's recently stopped eating all of his food. It was quite sudden, as he used to get excited and love his food. Now he doesn't seem bothered and occasionally grazes without eating everything he needs. He's still his playful self and nothing has changed behaviourally, nor has there been any sickness or diarrhea. I've taken him to the vets a couple of times (the second time for blood tests) and everything is completely normal and healthy. Can anyone offer any help or guidance?
