...the fence saga continued... the inevitable happened: they dug under !
Our next move: place cement patio stones along the fence.
We poured cement on that big hole. You should see their face when they try to dig now... haha
After a successful escape digging under the gate, those garden cement tiles did the job.
Snowball learned how to lift the "lock" up and escape, so Andy added the lower one.
The dog pen view from inside. 10 X 24, with a roof. They were digging so I filled the holes with rocks. The floor is covered with pine chips that I replace regularly.
I am happy to report that there were NO ESCAPES since.
