Identification: Tree Identification

Hi, Not sure of how to post his but we have a large tree in our yard. It is cedar like and is golden on one side. It is growing by itself, no trees around it. My dog had a seizure and she will often chew the branches. I am trying to find out if this could be a cause. The branches have no smell. Thanks in advance

 

One of many yellow foliage forms of Chamaecyparis lawsoniana.

 

Ditto to Lawson's Cypress Chamaecyparis lawsoniana.

 

Thank you!

 

Thanks!
