Onions. Poisonous?(4 Posts)
My stupid dog has just stolen a quarter of a medium onion. I had it in my head that onion and garlic were ok for dogs to eat but, having just looked it up on Google, it seems it may not be.
Can anyone point me towards a sensible, honest website please before I begin panicking?
Yes onion is, as is onion power (in cheese and onion crisps for example). Can't help with website as on phone at moment. sure someone else will be able to help.
Thanks! Think I'll be keeping an eye on him tonight.
Yes, onions are poisonous for dogs, but he'd need to eat quite a lot depending on the size of your dog.
Keep an eye on him over the next few days to see if he shows any signs of diarrea or abdominal pain. With just a quarter of an onion he should be fine. Any signs of illness, get him to the vet.
Here's a quote from online which matches pretty much what my vet said:
Onion and garlic poisoning Top
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 pets 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 animals 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.
