@Pamroger1 :
So you have an escape artist. Lol sorry to laugh. My old neighbor had one. His was little and they went out of town and left the old neighbor to tend. Many days I was an Olympic sprinter trying to catch that little ******. One day my friend saw me as she headed to work. First the dog runs out in front of her car, two seconds later here I come. Like a Nascar racer she headed the ****** off at the pass. Jumped out and he high tailed it back in my direction. Like a shot it got passed me. I spun on my bare heels and took off with my friend in her car behind me. That dog shot back under it's fence like a bullet. Right in front of the old lady. I hopped that 6 foot block fence and he just sat in the window. They left the slider open for it to go in and out. The old lady fed it twice a day.
When they got back I showed him where his dog was getting out and how I took extra flat stone I had and put under his gate. I literally watched that dog squeeze under the gate.
When you get your dog back, assuming he has a spot in the fence to escape, reinforce with flat stone he can't dig at. Or you can get some short wire fencing or chicken wire and run it around the bottom of the fence. Plant wild flowers or peas, cucumbers, etc in front to hide it.
