Can dogs (Dobermans) eat COOKED onions?

Question

And if they do, what would happen? Just wondering.

I make my dobie real food like meat, veggies, rice, grains, stews, treats and stuff, and I was wondering, would it hurt them? I have given it to them before, and they have been fine.

Also, I know chocolate is bad for them, but what else is?

I know raw onions are, but what about cooked?

Answer 1

No you can not give dogs onions or chocolate. Both are very toxic to them. The onions are hard on their kidneys. You've been lucky and so has Hammer. Meats,veggies (not onions) stews & rice is fine.Never feed your dog peanuts or anything with seeds in it.

Answer 2

I learned the hard way that even cooked onion is VERY bad for dogs. I had made some burgers with cooked onions for a picnic and of course, my buddy got what I dropped. That night, and the next day, she was vomitting at least once every hour. I was scared out of my mind. I hated seeing her like this because of what I gave her. I looked for lists of poisons (a day late) and found onions to be worse for dogs than chocolate. Unfortunately, chocolate is the one that has the worst reputation. I've actually known people to give Snickers to their search and rescue dogs (also Dobies) as rewards. I wouldn't suggest this without a vet's OK, but it is not a death sentence for a dog to eat milk chocolate. The danger correlation is with the increased amount of cocoa concentrated (the darker, the worse). Long story short, keep the onions away from the dogs. I'm sorry I don't have that list I refered to, but you should be able to find it with a search engine.

Answer 3

dont worry. a small amount of onion will not hurt your dog the worst that will happen is your dog will puke it up or have diareah but either way a small amoynt will nit kill your dog . tho only way that an obion will possibly kill our dog is if they eat a full onion but most dogs wobt touch a full onion because of the smell. but please dont let our dog mear any more onion. i u have any worries book an appointment with the vet but im pissitive a dmall amout wont hurt your dog( my dog, german shepared female, has eaten a sliced peice of onion before and never had a problem . no diarea or vomitin at all and its been a year + since ) so font worry too much but if u are then just see your lical vet :) okay its bot too serious

Answer 4

I posted this answer awhile back, so I'll just copy/paste it again...
"As a general rule, giving dogs chocolate on purpose is NOT a good idea. The problem with chocolate is the theobromine and the caffeine content. Theobromine, if ingested, can cause hyperactivity, vomiting/diarrhea, increase urination, irregular/rapid heartbeat, seizures and tremors. Caffeine content can also cause hyperactivity, rapid heartbeat, tremors and seizures as well. When it comes to chocolate and dogs, here are some helpful guidelines for how much is too much:
Milk Chocolate - one ounce per pound of body weight (more is harmful)
Semi-Sweet Chocolate - one ounce per 3 pounds of body weight
Baker's Chocolate - one ounce per 9 pounds of body weight (this is the most dangerous of all)
The other issue I see is the milk you're adding. Dog's do not possess the enzyme that is necessary to digest dairy products. It's not a deadly thing, but you'll suffer some concequences, nonetheless. Fragrant diarrhea (or terrible gas build-up) may very well follow.
As many others have mentioned other harmful foods, here is my own laundry list of dangerous foods:
- alcohol (duh)
- anti-freeze (duh again)
- avocado (can be lethal - guacamole too)
- broccoli (can cause upset stomach in large quatities)
- grapes/raisins (just 6 grapes CAN kill a dog)
- raw eggs (Avidin in it can cause major deformations)
- fatty foods (can trigger pancreatitis in prone dogs)
- liver (can cause vitamin A toxicity)
- mistletoe (in larger amounts, generally)
- mothballs (duh)
- nuts (can cause bladder stones, and many other debilitating conditions)
- green potatoes (contain solanum alkoids that can be dangerous)
- Plants (like rhododendron, azalea, oleader, rhubarb, cycads, yew, and other houseplants)
- nutmeg (can cause seizures and death)
- onions (one small onion can contain enough thiosulphate to kill a dog)
- salmon (especially raw, can cause salmon poisoning disease that can kill a dog within days)
- salt (can trap gas in the intestines and kill a dog)
- sugarless candy/gum (xylitol can cause liver damage)
- tomatoes (contain atropine, a dangerous substance)
- yeast dough (will rise in the stomach and can cause a rupture in the stomach or intestines)
- fruit pits/seeds (apple seeds contain arsenic ... so do peach pits)"

As for cooked vs. raw onions ... to my knowledge, cooking does not affect the amount of thiosulphate in the onion. Since that is the real danger in the onion, I would suggest not giving onions at all, raw or cooked.
Good luck!

Answer 5

Onions and garlic are other dangerous food ingredients that cause sickness in dogs, cats and also livestock. Onions and garlic contain the toxic ingredient thiosulphate. Onions are more of a danger.

Pets affected by onion toxicity will develop haemolytic anaemia, where the pet’s red blood cells burst while circulating in its body.

At first, pets affected by onion poisoning show gastroenteritis with vomiting and diarrhea. They will show no interest in food and will be dull and weak. The red pigment from the burst blood cells appears in an affected animal’s urine and it becomes breathless. The breathlessness occurs because the red blood cells that carry oxygen through the body are reduced in number.

The poisoning occurs a few days after the pet has eaten the onion. All forms of onion can be a problem including dehydrated onions, raw onions, cooked onions and table scraps containing cooked onions and/or garlic. Left over pizza, Chinese dishes and commercial baby food containing onion, sometimes fed as a supplement to young pets, can cause illness.

Onion poisoning can occur with a single ingestion of large quantities or with repeated meals containing small amounts of onion. A single meal of 600 to 800 grams of raw onion can be dangerous whereas a ten-kilogram dog, fed 150 grams of onion for several days, is also likely to develop anaemia. The condition improves once the dog is prevented from eating any further onion

While garlic also contains the toxic ingredient thiosulphate, it seems that garlic is less toxic and large amounts would need to be eaten to cause illness.


The toxic compound is unknown but the affect of macadamia nuts is to cause locomotory difficulties. Dogs develop a tremor of the skeletal muscles, and weakness or paralysis of the hindquarters. Affected dogs are often unable to rise and are distressed, usually panting. Some affected dogs have swollen limbs and show pain when the limbs are manipulated.

Dogs have been affected by eating as few as six macadamia kernels (nuts without the shell) while others had eaten approximately forty kernels. Some dogs had also been given macadamia butter.

Luckily, the muscle weakness, while painful, seems to be of short duration and all dogs recovered from the toxicity. All dogs were taken to their veterinary surgeon.

Pets owners should not assume that human food is always safe for pets. When it comes to chocolate, onions, garlic and macadamia nuts, such foods should be given in only small quantities, or not at all. Be sure that your pets can’t get into your stash of chocolates, that food scraps are disposed of carefully to prevent onion and garlic toxicity and that your dog is prevented from picking up macadamia nuts if you have a tree in your garden.



Other potential dangers
Pear pips, the kernels of plums, peaches and apricots, apple core pips (contain cyanogenic glycosides resulting in cyanide posioning)
Potato peelings and green looking potatoes
Rhubarb leaves
Mouldy/spoiled foods
Yeast dough
Coffee grounds, beans & tea (caffeine)
Hops (used in home brewing)
Tomato leaves & stems (green parts)
Broccoli (in large amounts)
Raisins and grapes
Cigarettes, tobacco, cigars

Now, Cigarettes, can just make your dog vomit, it has never made my dogs sick, or patients dogs sick, when out for a walk, and pick one up off of the side walk!

Answer 6

I imagine that you are not fixing your dobies a plate of cooked onions. I have and do feed my lab cooked foods that contain some chopped onion. Food that is prepared for us that she gets a little bit of. Would not recommend that they eat a large amount. She also likes grapes but only gets a couple at a time. (seedless grapes) Plants outside can be poisoness such as Rhubarb leaves. The stalk is edible, but the leaves are toxic.

The bigger breeds can eat most anything but in small amounts. Mine loves berries,strawberries, raspberries,blue
berries. She will pick all the berries before we do if given the chance.

Answer 7

NO, NO NO, NO, NO!

Onions and garlic should not be given to a dog raw, cooked, or in powder form.

Like chocolate there is a toxin in them that can make them potentially fatal to canines.

No grapes, chocolate, onion, or garlic. :)

Answer 8

Onions are toxic to dogs as well as grapes and chocolate. It can kill them in high amounts and if not that make them extremely ill.

Nope. Onions and things that look like onions are bad. Onions and grapes and chocolate... Poor dogs.
Other things are about as healthy as they are for you. And your dog could be allergic to anything, so if s/he's having a problem you might want to test different foods.

Answer 10

Any onion, raw or cooked, are bad for dogs, I have dobs too. Also, alcohol, baby foods, bones, cat food citrus fruits/oil extract, grapes/raisens, mushrooms, garlic, potatos or tomato leaves and stems, raw eggs or fish, tobacco, yeast dough. Hope this helps.
