I've only had a tree once with animals in the house and it was a disaster. I currently have two parrots, a cat and my Kyleigh ... a tree? NOPE, not gonna happen!!!
And you have a male ... forget eating it ... will he see it as his indoor bathroom LMAO!!!
Lots of people on here have trees and dogs / puppies and have had no problems.
I think a lot of it is how you are going to approach it, and how you are going to stop him if he's super interested!
Every dog is different! Some won't care, other's will want to destroy it!
