Title: Shade trees not toxic to dogs in Kempner TX
Answered by: Nan Hampton

QUESTION:

Dear Mr Smarty Plants, we are looking for shade trees to plant around our home in Kempner, Tx. I saw another family that asked a similar question but we have dogs and holly or oak trees are toxic (my pups eat everything). Can you recommend some pet friendly varieties to provide shade for my puppies? Our yard is high alkaline and full of limestone, we get a fairly common 10 mph wind, no trees yet and tons of sun. Thanks in advance for your advice!!

ANSWER:

The ASPCA Toxic and Non-Toxic Plant List – Dogs doesn't list oaks as being toxic to dogs.  Certainly, they aren't to deer since they feast on the acorns and tender leaves.    However, Poisonous Plants of North Carolina, which is aimed at humans says that raw acorns can cause problem but  "causes only low toxicity if eaten".  Pennsylvania's Poisonous Plants and Cornell University's Plants Poisonous to Livestock, which are focused on livestock, list it as toxic with horses and cattle being the most often affected.  The ASPCA list does say that Ilex opaca (American holly) and Ilex aquifolium (European holly) are toxic to dogs.  We can find you shade trees, however, that are neither oaks or hollies and are not toxic to dogs.
