Signs of Onion Toxicity in Dogs

Onion Toxicity

The initial onion toxicity symptoms are relatively mild. At first, the dog will just have vomiting and diarrhea, but as the toxicity progresses, the symptoms worsen.

As more red blood cells are destroyed, more signs appear. Lethargy appears quickly due to decreased oxygenation. When they exercise, their stamina will significantly decrease from what’s normal.

Their gums, which should be bubblegum pink, may turn a pale white or bluish color. When they urinate, their urine might be dark red due to elimination of dead red blood cells. Left untreated, severe anemia is fatal.

If you smell garlic or onion on your dog’s breath, you should immediately consult the nearest vet.

How Are Dogs Treated for Onion Toxicity?

Vets treat onion toxicity based on the information they receive from dog owners and the symptoms of onion toxicity they observe in dogs. In case of dogs accidentally ate onions, vets will want to know about a few things:

When did dogs eat onion and how much onion do they eat? Onion consumption by your dog affects its treatment. Based on the information they receive, vets decide whether to induce vomiting or not.

If you immediately take your dog to the nearest vet, your vet may induce vomiting. Vomiting helps remove toxic onion from your dog’s body.

Onion ingestion in dogs is a bad omen. In severe cases, where dogs’ red blood cells drop to dangerous levels, dogs may undergo a blood transfusion.

If onion toxicity is left untreated, it will damage the liver. Liver damage is irreversible, so if your dog winds up with a damaged liver, it will likely progress as they age.

Onion toxicity can kill your dog, so if you think your dog has consumed onion in any form, then it’s imperative you take your dog to the vet immediately. Onion poisoning is a serious issue.

The sooner you seek treatment, the more likely it is your dog will recover unscathed. Some dogs, such as Shiba Inu, are more prone to onion toxicity than others. A small amount of onion can hurt Shiba Inu more than other dogs.

Don’t ever wait for symptoms to appear before you seek veterinary care. Many dogs don’t show symptoms for days. Waiting too long allows the toxicity to progress quite a bit, making it more difficult to recover dog health.

When you see your dog eat an onion, call your veterinarian or the Pet Poison Helpline for an immediate action plan. The longer you wait, the longer it will take your dog to recover-if they do at all.

  1. I believe that avoiding refined foods may be the first step to losing weight. They will often taste fine, but packaged foods currently have very little vitamins and minerals, making you eat more to have enough vigor to get over the day. Should you constantly consume these foods, transferring to whole grain products and other complex carbohydrates will give you more power while feeding on less. That is a good blog post.
