Is Aloe Gel Toxic to Dogs?

Aloe contains saponins, elements that have a toxic effect on dogs if they eat them. In the Natural Health Bible for Dogs and Cats, veterinarian Shawn Messonnier notes that eating aloe vera can result in severe diarrhea for your dog. Other poisoning effects of aloe vera on your eat-anything dog are darkened urine, muscle spasms and weight loss.

Although aloe should never be given to your dog orally, you can still use it externally for its topical benefits -- if you ensure that your dog doesn't lick the area to which you apply the gel. Used on the skin, aloe is effective in treating conditions such as hot spots and allergic reactions. The American Animal Hospital Association also notes that aloe can be used to treat cuts and will protect wounds from infection.

The list of plants that are toxic to dogs is longer than just the aloe vera plant. The dangerous saponins in aloe can also be found in buckeye, English holly, English ivy and nightshade. Azaleas and rhododendrons, lily of the valley, milkweed, daffodils and chysanthemums are also among the many plants that can cause serious symptoms like nausea, vomiting and shock and may even result in death if your dogs ingests them.

For every plant that is potentially toxic, there is one that is perfectly safe for your dog. Many are herbal and can be used for medicinal purposes. Just many are plants that you may simply want to cultivate in your garden without worrying whether or not they are dangerous to your dog. On the list of safe herbs for your dog is licorice, burdock, red clover and catnip (yes -- catnip!). As for your flower garden, you can rest assured that your dog will be safe around begonias, geraniums, miniature roses and Swedish ivy.
