I have a 70lb Bernese mountain dog, and we currently have her zip line set up between two trees. However, one of the trees is going to be cut down because it's posing a risk to our house. Unfortunately, I can't find any suitable replacement trees for the zip line. I'm considering installing a post in the ground instead. The zip line is about 10 feet up—will a 4x4 post, cemented below the frost line, be sturdy enough for this?

I actually set my zip line low to the ground, and it works just fine. Just be careful with weight distribution if the dog runs on it!
I'd recommend using a 6x6 post instead of a 4x4. At 10 feet in the air, a 4x4 might get a bit wobbly, especially with a big dog like yours. A beefier post will definitely help it stay stable!
Ok thanks. That’s what I wasn't sure about.

Doesn't the dog get tangled in it?
