THat is Higgs my friend Jean's dog. HE joins us about every other week or so. Now you know why I say Mary' gallops.
I have 4 local places like this, three of the wooded that are not official dog parks but no one cares. So my guys get a good run almost every day weather permitting. I am certain it has had good effect on Mary. Keeps Pepper and Victor well muscled. THe down side is when the weather is good and we can't go. They expect it.
