Marilyn, she doesn't dig under the fence, she goes right THROUGH it!
I watched her last night testing the new run. She sticks her nose in the opening of the netting and presses as hard as she can trying to force it out to the side and keeps at it till she has a hole large enough to squeeze herself through. All she's going to get with the new fence is a really sore nose.
Montana was a digger... we've not had another since her and I really hope not to. lol
