Plants Potentially Poisonous To Dogs

The following commonly available plants could potentially pose a hazard to animals. This list is not meant to be all-inclusive. If you think your animal may have ingested a poisonous plant, contact your local veterinarian. 

Beware of mulch used in landscaping made from cocoa bean hulls. It contains Theobromine, which is the ingredient that makes chocolate-especially dark or baker’s chocolate. This could be potentially toxic and even fatal to dogs if ingested. Animals seem to be attracted to the mulch’s sweet smell.
