The dogs check the perimeter at least 2 times a day. They start at the back of the horse pasture and follow the fence all the way around up to the house. It is a ritual for them. On a different note, my Dad is in the hospital with a bleeding ulcer, so Dad if you are reading this, get better soon. There are pictures to take!
