One of my daily paintings from my blog (dogandpetpaintings.blogspot.com), this is a larger painting than usual - it is 10"x8" - because I felt the dogs needed the extra room to spread out. Apparently, greyhounds spend 18 hours a day sleeping or even more, given half a chance. In contrast to their sprinting performance: at maximum acceleration,they can reach full speed of 43mph within six strides of starting; the only other animal that can accelerate faster over a short distance is the cheetah, which can reach speeds of 68 mph over 3-4 strides from a standing start. No wonder they're sleeping. I feel tired just thinking about it.
