My situation:

I am thinking of installing the fence myself. I have around 100 feet in my backyard that has chain link fence that is only 4 foot high. Rest of the sides have 6 feet wooden fence. My dog easily jumps the chain link fence. The tough job is is to dig 20 holes each 2 foot depth and set the fence

My question:

1) is 2 feet enough depth for a 6 foot Fence
2) Do I need to put concrete while setting up the fence.
3) is it easier to install a 6 foot Chain link fence since the posts are smaller in Diameter? Because I am not looking for a Privacy fence, but just to keep the dog in

Thanks

 

1) Yes, unless you live in a swamp.
2) Yes.
3) Yes.

 

as a lad I installed miles of chainlink, always built the entire thing and then poured the concrete in the hole. the trick is to use a long pole ,dig the holes ,drive the posts in past the bottom of the hole cut the tops , set rails and stretch the fabric,works great and allows you to keep those dogs in check the first day!
lots more silly ideas that work where that came from,built a few hundred in wood also.
