Is Barbados Aloe safe for dogs?

Yes, Barbados Aloe (Aloe barbadensis) is potentially toxic to dogs. The plant contains anthraquinone glycosides that irritate the digestive tract and can cause vomiting, diarrhea, loss of appetite, and in some cases tremors or changes in urine color.

Most dogs develop vomiting and diarrhea within a few hours of ingestion, often accompanied by lethargy or loss of appetite. Watch also for red or pink urine — the latex in aloe contains pigmenting compounds — and, rarely, tremors. Uncomplicated GI signs typically resolve within 24 to 48 hours with supportive care.

Remove any remaining plant material from your dog's mouth and offer fresh water. Do not induce vomiting at home — Pet Poison Helpline specifically warns against giving hydrogen peroxide or other improvised antidotes without speaking to a professional first. Call your veterinarian or ASPCA Animal Poison Control at (888) 426-4435 and have the plant's name (Aloe barbadensis / Aloe vera) ready.

The toxic compounds — anthraquinone glycosides — are found in the latex layer just beneath the outer leaf skin, not in the clear inner gel. However, the whole plant should be kept away from dogs since it is difficult to separate the latex from the rest of the leaf during chewing.
