Stella the dog is a perfectly healthy dog who has a quirky way of stopping herself after she’s been running and playing. She uses her hind legs as brakes and glides into the grass to cool down. She apparently only does this on the grass and only after she’s been fetching and running around. Stella’s owner assures us that she is a healthy yellow lab and has been tested for EIC (Canine Neuromuscular Disease) and has no medical issues at all so please rest assured this dog is fine.
