Q: I often let our dog play around in the yard while I garden. Are there any plants I should be aware of that could be poisonous to her?

A: A number of common plants are toxic to dogs: azaleas, yews, tulip bulbs, sago palms, and chrysanthemums, to name a few. The ASPCA’s website provides a longer list, including which parts of the plants are poisonous and explaining what damage the toxin does. In most cases the plant, or its poisonous part, has to be eaten to do harm, so if your dog doesn’t have a penchant for gnawing on the shrubbery, he’s probably safe from the rhododendron.

On the other hand, just one sago palm seed can make an animal gravely ill. Put a sago palm together with a puppy who’s in the everything-goes-in-the-mouth phase, and it’s easy to see that tragedy can result.

Now, obviously, you and your dog are going to be hanging out in your backyard, and most dogs don’t chew the rhododendrons. But just in case, identify any potentially dangerous plants and familiarize yourself with symptoms of poisoning by them. In special cases, like that chew-it-all puppy, physically prevent access to toxic plants.
