Can Dogs Eat Crab Apples?
No, dogs cannot eat crab apples due to the trace amounts of cyanide in the crab apple seeds, leaves, and stems. While the flesh of the crab apple is safe to eat and can provide dietary fiber and nutrients like phosphorus, calcium, vitamin A, and vitamin C, the seeds and stem contain cyanide, which can lead to poisoning. Make sure your pet ate their dog food before you allow them to roam in the yard to prevent them from snacking on the fallen fruit.
Why Crab Apples Are Poisonous to Dogs
Crab apples contain a compound called cyanogenic glycoside, which yields cyanide. Cyanide is in the apple seeds and apple stem as well as many parts of the tree, including the branches and leaves. Eating these parts of a crab apple can lead to cyanide poisoning. Symptoms of cyanide poisoning include an upset stomach, vomiting, difficulty breathing, respiratory congestion, and changes in your pet’s heart rate. Cyanide poisoning can also lead to respiratory failure and lowered blood oxygen levels in serious cases. In addition, the apple core can be a choking hazard for your pet.
What to Do if Your Dog Eats Crab Apples
While crab apples contain cyanide in small amounts, dog owners should be wary of their pooch eating fallen apples or crab apple leaves in their yard or landscaping, as large amounts of this toxic substance can be dangerous. If your dog eats large quantities of crab apple fruits or any part of a crab apple tree, look for symptoms of poisoning from cyanide—digestive upset, vomiting, panting, and difficulty breathing—and contact your local pet poison control center.
Before Sharing With Your Pooch
