Hi guys, I'm having some real trouble with one of my bitches who keeps digging underneath the yard fence. She seems to be determined to get out. Our yard is big. Yes she could do with a bit more exercise, but she's not THAT under-exercised. I don't know if it's just her prey drive driving her, or what. But I can't have her running loose all over the farm. Especially since she is usually followed by my male who have a beef with the workers and is prone to chasing them. We pack the fences with rocks, but she is a strong dog and if she becomes determined she just pushes them out of her way. So I'm thinking of installing an electric fence to put her off. But now I don't know which type is better. The normal hot-wire like farmers use to keep jackal out or the true pet fence type that requires her to wear a special collar. I'm thinking depending on price the first one might be better. Might also put some other critters like skunks off coming into the yard. Does anybody here use any of those types and what's your experience with it? Good? Bad?
