why does my mongrel never want to eat out of his own bowl?

my mongrel has food aggression so he has to eat separate from the other dogs. he can see them but a baby gate separates him from the others.
i noticed that he growls a lot more when he is hungry so i can gage how hungry he is when we feed the dogs.
but no matter how hungry he is he eats a few bites from his bowl but won’t eat more. then when i finally think he is finished and doesn’t want to eat he comes out and eats the left overs of the other dogs.
why is that? he has the exact same food as the others, the same bowl. we tried different types of bowls as we thought it might be that but nothing. he still prefers to eat out of the other dog‘s bowls?
thanks
i am doing a number of things and he is getting much better.
he just sometimes decides to eat the other dog‘s food whatever they left over

Why puppies won’t eat out of food bowl?

We have two 5 month-old puppies. They love their dog food (Taste of the Wild wetlands formula) but they don’t always eat it out of their bowls, which are metal. They will eat it off of the floor, or out of our hands. We try to avoid hand-feeding them because we want them to eat out of their bowls.

They also don’t eat their food servings all at once. I give them about 1 1/2 cups per serving, 3 times per day. But they leave about a full cup in their bowls when I feed them, and go back and nibble on it at random times.

Do they not like the metal bowls? Should I try getting new, plastic ones?

What do you suggest?

My dog won’t eat, with a possible cause being loss of a friend. Can anyone help me?

Recently I lost a dog, and now the one dog I have left isn’t eating well. The dog I lost was in our other dog‘s whole life, so is it possible she’s not eating because she’s lonely? I heard a dog will be sad but that they usually get over it quicker than humans.

It’s been about 3 weeks and slowly she’s been eating less and less. If I offer her people food she won’t hesitate to eat it, and she doesn’t seem to be in pain. She literally looks depressed and it takes effort just to get her to play. I try to be sure I take her outside enough (but because of the cold I keep her inside most of the time).

Do you think the loss of her friend caused it, or maybe the weather? I guess I’m not so much looking for a reason as to finding a way to get her to eat her food again. Has this happened to anyone before?

I’ve even tried putting food she loves into a bowl of cat food (she likes cat food more than her dog food) and she picked out the other food. She’s never been like this before.
Thank you for the replies. I will try maybe pouring broth over her food. I’ve been letting her do things she couldn’t normally. She can free range the house for the most part. I talk to her and pet her and try to keep her company, but I will keep trying.

I hope she doesn’t starve herself to death =/
