Summer dog yard maintenance includes keeping the grass, or as we tend to have weeds, mowed. This helps keep the bugs to a minimum.
We have help in this with two ponies. We take turns letting one of them out. They just love the dog yard; which can be very frustrating. I have seen the ponies grazing on short grass in front of the dogs and leave the tall grass on the septic system alone. I than have to get a more traditional mower out for the septic system.
