Three Polish Lowland Sheepdogs chased the lure into the AKC Fast CAT rankings in 2017, and Polski Dumny Piotr Van Het Goralenhof TD HSAs blazed to the front at 18.56 mph — 100 yards in a flat 11.02 seconds, clear of the field. That top speed makes the Polish Lowland Sheepdog the 170th-fastest of 191 breeds in 2017. Behind the leader, the top 3 averaged 17.0 mph.
