In addition to looking great, Money Trees are relatively safe for homes with pets. The plant is considered non-toxic to dogs, but can cause mild reactions if ingested. If leaves are ingested, they could cause an upset stomach, trigger a vomit response, or cause a dog’s tongue or mouth to swell. So, if your dog is particularly prone to chewing on things, you can place this plant out of their reach or you may want to forgo a Money Tree.
