What is the Prognosis of Onion Poisoning in Dogs?

The prognosis of onion poisoning in dogs is variable. A dog may recover from onion poisoning at home, or it may need to be hospitalized for intravenous fluid treatment and medication. Dogs with severe signs of toxicity will require emergency care, including oxygen therapy and other supportive measures.

Typically, a dog that has eaten a large amount of onion will show signs of toxicity within six hours. If symptoms develop more than 12 hours after ingestion, the prognosis is more favorable because the poison has likely been cleared from the body by then.

How To Prevent Your Dog From Eating Onions?

Onions can be harmful to dogs. It is important that you educate your family about the danger of onion in dogs so you can prevent them from eating it.

Store it where your dog can’t reach. Keep onions out of reach of your dog and away from areas where your dog goes often (i.e., kitchen, dining area). Also, keep onions away from any garbage bins or trash cans where your pup may get into those items.

Use a baby-gate to keep your dog out of the kitchen and eating areas. You can use a baby-gate to keep your dog out of these areas while cooking or eating their meals. If you are not supervising your pup at all times, crate train them so they do not eat any harmful items while you are not around to supervise them.

Teach them the ‘’leave it’’ command in case they see any onions lying around outside or on the ground somewhere else outside off-limits areas like outdoors (backyard).
