Yesterday, the dogs were in the backyard as I was picking up poo. I came in to toss the bag and suddenly my son burst in the front door saying Delilah had dug under the fence and got out. He immediately got her back into the back yard so she's fine, but how do I discourage her from digging out? This is how she got out at the previous house and got attacked by a big dog and had her pelvis broken. A few of the other dogs rushed over to where she got out this morning and looked to be intent to try to make the hole bigger. This is quite frightening to me. I am going to Lowes to try to get a 4x4 to dig into the ground at that spot, but I have a lot of fence (I live on a corner) and need a way to try to discourage her from trying somewhere else.
