The Pawm Springs Memorial Dog park here in Sugar land is not exactly senior dog friendly. This is in reference to the pond/lake. I don't know why it was designed to drop off at the edge like a swimming pool. Perhaps this happened after erosion but I'm assuming the entire thing is concrete just like a pool. Whatever the case, it makes arthritic dogs apprehensive about stepping in and a great deal of difficulty getting out. Of course the young pups come running and jump but the older dogs not so much.
