The 5 Reasons Your Dog Smells Like Maple Syrup

1. Diet

Certain foods or treats that contain maple syrup, molasses, or other sweet ingredients can impart a sweet smell to your dog’s breath. If your dog got into your pancakes or other goodies when you weren’t looking, there’s a good chance that you will smell it in their mouth. They might also get some on their fur and face, increasing the fragrance. These treats can even sometimes change the odor of their urine. Fenugreek seeds, which are sometimes added to foods and medicines, can also make your dog smell like pancakes, but they are not that common in America.

2. Wild Plants

A few wild plants can cause your pet to smell like maple syrup if your pet chews on them, as they change the fragrance of their breath, urine, or both. One such plant is the California cudweed, which has a hairy appearance, whitish leaves, and small white flowers. You will find these plants growing wild in California, and your dog can easily eat them or rub the flowers and leaves on their coat as they play.


3. Yeast Infection

Dogs with yeast infections, particularly in their ears, paws, or skin folds, may emit a sweet or musty odor that resembles maple syrup. Yeast overgrowth is typically secondary to another health problem that may alter the skin’s defense mechanisms.

Common problems that contribute to yeast infections include food or environmental allergies, immune system issues, or hormonal problems. Fortunately, these infections usually clear up with topical treatment, including shampoos, lotions, wipes, and washes, or with oral medication in severe cases.

4. Bacterial Infection

Some bacterial infections, including certain ear and skin infections, can produce an odor resembling that of maple syrup. These infections can arise from inflamed ears, wounds, hot spots, or other sources of bacterial growth on the skin. These can also be treated with medication prescribed by your vet.


5. Ketoacidosis (Canine Diabetes)

If none of the other reasons on this list are likely, the sweet smell from your dog might result from ketoacidosis, a severe complication of canine diabetes. Diabetes occurs when the body doesn’t create enough insulin or doesn’t respond to it properly. The first type is more common in dogs.

Temporary insulin resistance can also occur when a female dog goes into heat. Any form of diabetes leads to too much sugar in the bloodstream. If the sugar levels are high, the body starts producing ketone bodies, which can cause the dog’s breath to smell sweet, often reminiscent of maple syrup. When diabetic ketoacidosis develops, treatment must be started immediately because major metabolic complications can occur.

Summary

Your dog can get into food or plants that can cause them to smell like maple syrup. If it’s one of these reasons, it will likely clear up in a few days. Certain yeast or bacterial infections might also smell sweet, in which case, your dog will require medication from your vet to clear the infection. However, if the smell is persistent and your dog is unwell, it could be a sign of ketoacidosis, a complication of canine diabetes. This is a serious endocrine disease for which there is typically no cure, though dogs can still live happy lives with proper care from their vets and owners.
