When you say human food what are you referring to?
Meats, eggs and berries are fine I wouldn't feed them from the table while I'm eating my dinner. You can feed meats raw or cooked but only raw bones and not the weight bearing bones, stay away from smoked bones also.
I wouldn't feed them too many vegetables, dogs systems cannot process fibre and chlorofyll from plants (they eat grass, comes out the same as it went in).
Nothing seasoned with salt and pepper, garlic or onions. Someone posted a link not to long ago of things you cannot feed a dog that are poisonous (grapes, onions, tomato plants large amounts of garlic).
Stay away from carbs, dogs don't need them, rice, pasta, anything soy, grains, wheat or gluten |
