"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 petís red blood cells burst while circulating in its body.
At first, pets affected by onion poisoning show gastroenteritis with vomiting and diarrhoea. 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 animalís 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."
This according to Dr. C. Day, BVSc BSc MACVSc - a veterinary surgeon, an animal behavior consultant from Australia.
Personally, my dogs have always eaten onions and other vegetables. They don't eat an entire bag at once, but I would think if the toxicity built up in their systems, my Yellow Lab would never have lived to age 15.
I put onions in almost everything that I make, years ago I heard that onions are good for the heart. Maybe there is some truth in that, I've never had high blood pressure.
Do any of you feed your dogs onions?
Has anyone else heard about onions or garlic being toxic to dogs?
My vet says you can sprinkle garlic powder or garlic salt on their food lightly as an extra preventative for fleas. I havent tried it yet but I looked it up every where I could find and onions are the bad thing but nothing about garlic in small doses. I think it's what you give them from the beginning. My oldest collie has a tremendous sweet tooth. His favorite being Mike and Ikes..like the old good and plenty..just shake the box and he sure wakes up!!
i am very surprised to hear about the garlic. garlic is an ingredient in a lot of dog foods and is also used to prevent fleas. whether it really works for flea prevention i do not know.
i have heard about the onions. i heard it is more dangerous to feed raw onions then it is cooked ones. both my cats and dogs have eaten the onions in chinese food and have never had problems. that is not to say an animal wont...just that mine have never had a problem.
scout has a huge sweet tooth also. her favorites are m&m's. when she hears the m&m bag she comes running.
I don't feed my dogs anything with onions but I don't think one little sliver will kill them. I also give my dogs M & M's everyone once in a while but they do only get 1 each. As far as garlic is concerned. I give my dogs 2 Brewers Yeast and Garlic pills every single day. I always gave my dogs frozen grapes and raisins. Now, there are reports that they are toxic also. I still give them a few frozen grapes on a hot summer day. My dogs are completely fine.
In my honest opinion, a little of this or that isn't going to harm them. If you feed them things that are suppose to be harmful to them in large amounts and every single day, I'm sure you will be looking at tons of problems and probably even death.
wow, i'm rather shocked. my dogs eat onions and garlic all the time as they eat our table scraps. i haven't noticed any adverse reactions, except perhaps for the occasionaly nasty, um, flatulence. i've always thought that garlic was a natural parasite repellant as well, not just for fleas, but ticks and some worms. hmm, learn something every day, although i'm not sure i'm buying it.
I have heard that about onions, grapes, raisins, seeds from certain fruits etc. I have a whole list on my refrigerator of toxic foods for dogs. My two got into an old Taco bell bag the other day. I have no idea what they ate but they are both fine, Max just has really stinky farts lately. LOL!!! (Must have been a bean buritto)
