I am putting this here instead of the food or training sections, but I am not sure it is a health issue. Hoping for some new ideas.
Back in September, Conner started refusing to eat his breakfast some mornings. He always ate dinner, so I didn't worry much at first. He started refusing more often, and I had my vet check him over, but everything else was completely normal. I thought maybe he had just decided he didn't want to,eat in the morning anymore, as I have heard older dogs sometimes do. He is 10.5 and definitely not a morning dog. Just about the time we were going to run some blood work, he started eating regularly in the morning again. Then he stopped, again.
I have tried nummy additives, makes no difference. I tried offering him some of the different things he eats (he is raw fed) one at a time to see if there was one thing he had gone off of. Nope, ate everything. His poop has been completely normal the whole time. The mornings he doesn't eat, I put the food in a plastic container in the frig and give it to him for dinner, and he happily eats it. He eats treats, sometimes he will eat some kibble, but not often and not much.
So, anyone have any ideas? Anything we haven't tried other than a lot of fancy tests? Or should I just expect this to be our new normal?
