I hear you Laura, completely. Fortunately he loves anything bell pepper, and there are about 1600 µg beta-carotene in a red bell pepper. So I make sure he gets plenty of those, as well as other colored peppers since they have slightly different nutrient profiles. I'm not giving up on orange stuff yet. I think he might eat the dried carrots out of his next so he's getting those. And I'm not out of tricks for other foods as well. He didn't eat raw hands but I haven't cooked and mashed for him yet I can also take away his dry commercial food and essentially forced him to eat whatever fruits and vegetables I put in his bowl. Right now I only give him a little bit of the dry stuff at night when I go to bed at 11, small snack. I can withhold that so he eats what I give him earlier in the evening.
AJ, I used a trick similar to social eating to try to get Parker to try new stuff. I eat a bunch of it in front of him in hopes that he would get curious and if you want to try something. It's been less than successful unfortunately my dog, however, refuses to eat unless we are home!
