What Plants are Toxic and Unsafe for Pets

As a pet owner, I am always concerned about my pet’s safety when it comes to what I plant in my garden and yard.  If your dog is like ours, she wants to join in when we are working in the yard.  She will eat blueberries when we are harvesting them and her favorite is to pull carrots up to eat.

You need to be careful since they will eat things they shouldn’t such as grapes and leaves of toxic plants.

The best advice if you think your pet has ingested anything toxic is to contact your veterinarian immediately with as much information that you can provide.  It is always better to be safe and the earliest contact with professionals the better to treat and cure the dogs.

Here is a list of toxic plants, symptoms to look for, and the severity of toxicology.

Sweet Peas

I have not updated the symptoms but this is a very dangerous plant that I just realized that I have grown in my garden for several years.  If you love growing them as I do for the wonderful colors and fragrance be sure you keep your dogs away from them since 1 pea can kill your dog if they ingest it and are not treated.

Know what is potentially toxic to not plant in your yard, or limit access for your pet to get to them so that you can still enjoy them and keep your pet safe.
