No. Never feed shallots to your dog. Shallots belong to the onion family and any form of onion is a strict no-no for dogs. 

Shallots and onions contain a toxic principle known as N-propyl disulfide. In excess, it can cause the red blood cells or erythrocytes in your pet to break down. Over time, this oxidative damage can cause severe anemia in dogs.

Certain dog breeds like Akita Inu and Shiba Inu are even more susceptible to N-propyl disulfide toxicity since their red blood cells tend to break down even faster.

Shallots can also cause allium toxicity in dogs. Symptoms of allium poisoning can begin with nausea and vomiting. The dog might also suffer from gastrointestinal distress and diarrhea. All forms of allium are toxic to dogs. Even a tiny quantity of 15-20 grams per kg of body weight can result in allium toxicity. This means puppies and small-breed dogs are particularly susceptible to it. So, please avoid feeding all forms of shallots to dogs – cooked, raw, or powdered.

If your pet has accidentally ingested a couple of shallots, do call your vet right away.

To ensure your pet will live a long and healthy life, it is always a good idea to invest in pet health insurance. Preparing for the unexpected guarantees money is never an issue in keeping you pup healthy.
