|My vet says typically if the food allergies are severe, you'll see either diarrhea or constipation, something going on digestively first. Then it shows up in the eyes and ears, more gunk than normal. Then it starts to effect the skin, generally the feet and lower legs. Dogs will often lick and bite the legs and paws, and you can tell that they feel itchy.
It seems that if a dog is biting and scratching their sides a lot, that may be environmental allergies like freshly cut grass, lots of pollen in the air etc. That tends to show up on their bellies and undersides of legs, too.
Incidentally, I have severe allergies to some foods and the same process happens with me when I ingest something accidentally; digestive first if it's not bad enough to make my throat swell, then eyes/ears, then skin itching and hives. It's no fun and only benadryl seems to help.
