As a dog owner and plant enthusiast, I know how challenging it can be to create a pet-safe indoor garden. While houseplants add beauty and freshness to our homes they can pose serious health risks to our furry friends. I’ve learned through experience that many common indoor plants contain toxic compounds that could harm or even be fatal to dogs if ingested.

From my research and consultations with veterinarians I’ve discovered that popular houseplants like lilies philodendrons and pothos are particularly dangerous to our canine companions.
