Sometimes Duke doesn't eat. I will put his breakfast out at 6 or 7 depending on the day and sometimes he won't eat until its supper time. This morning he ate maybe 3 bites of his food. I would give him a little time and see if he eats later. He will eventually get hungry.
Hanna went thru stages of this, add another boxer, they will never leave a meal untouched. I would just watch him, and see if he will eat this evening. If he is not by tomorrow am, then Id call the Vet - possible blockage if he is not pooping, or maybe something else. Try some alternatives as well -boiled chix etc.
Oh, maybe he is on Hunger Strike until he gets his buddy Bruce back!!!
***Good Luck John, Hope he eats!!! Try loading you kids with some food, and play like its treats! Who could resisist food from your two cuties!!
Charlie will miss meals, especially when we travel. He is on edge constantly. Like others have posted, I'd make sure he's still able to poop. If he can't, more than likely something is blocking the intestinal tract. I think most dogs skip meals every now and again. I will say I don't recall Sadie ever missing a meal, I call her my little garbage disposal. I think that girl would eat anything if you let her.
