This small tree with berries sprung up in my backyard a couple of months ago

Located in MA. I have dogs and want to ensure it’s safe for them to be around. They don’t typically eat things off the ground but if it proves toxic I’ll cut it down to be safe. Thanks!

This I believe is Glossy Buckthorn, and these berries are known to be toxic if ingested which includes for dogs. Definitely not something you would want your dogs to eat, and also invasive. I would recommend cutting it down.

Oh man. Thanks so much for the help. We will cut it down ASAP

Might need mechanical and/or chemical help, and ongoing surveillance also required. It's a bad one:

Appreciate the heads up. I just did some research and ordered the Buckthorn Blaster starter kit.

Solved!
