We had a small group of only 6 at play date today. There were some pretty good sprints, but for the most part the dogs waded through the belly-high weeds (as mentioned before we had a really wet winter). It had all the makings of an African safari documentary - "the greyhounds, among the fastest of the land mammals, reaching speeds of 45 MPH in 3 strides, disappear in the undergrowth, stalking their prey, a defenseless and unsuspecting red squeaky ball." Molly, in particular, has an obsession with the red ball. We have the same ball in yellow and she just turns her considerable nose up at it.
