I had coffee with an old acquaintance a bit ago to talk about an up-and-coming visit from her daughter and her new puppy Monroe. Seems Monroe likes to chew on almost everything, including plants, and there lies the concern. This long-time gardener knows many plants in her garden can be toxic to small animals and some, like castor beans, can be deadly.


When it comes to researching allergenic and deadly toxic plants my first go-to book is The Allergy-Fighting Garden: Stop Asthma and Allergies with Smart Landscapingby Thomas Leo Ogren (Ten Speed Press). First published in 2015, it gained world-wide notability. In the book, Ogren explains dogs get allergies just like we do, but more often than not, a pollen allergy will make a dog scratch and itch, rather than have a runny nose. That said, sometimes dogs will respond to allergenic pollen much the same as we do…their nose will run, their eyes will get red, and sometimes they’ll sneeze.

Other things Ogren says to consider with dogs and allergies: Do not use cocoa mulch as some dogs will eat it, and it can poison them. Also, do not leave hardwood sawdust around dogs, and do not use it for bedding as it can trigger numerous allergies. Red cedar shavings can also cause allergies in dogs.

Ogren also says, folks often blame the dog for their allergies, when what is much more common is that in their yards they have highly allergenic plants, and the dog comes in contact with these pollens, they get on its fur, and then the dog brings these allergens inside. Rather than getting rid of the family dog, it makes much better sense to get rid of the allergenic plants in the yard, and then replace them with allergy free plants. That’s why this book is so valuable. And dog parks may be the answer if you have plants or trees you can’t part with.

Ogren also explains, “Some dogs chew on or eat all kinds of garden plants”. If your dog does this or you babysit a dog that does do try to stop it, and consider getting a copy of Tom Orgren’s book, Safe Sex in the Garden, as it has a large, comprehensive listing of almost all common and uncommon garden plants that are poisonous to dogs, cats and children, too. It’s out of print now, however, used copies are still readily available at very low prices: $6 to $8 online from Amazon.com or other book sites.
