Vets get to know their pets with Whistle, too

“I routinely use Jack’s Whistle to let me know when he needs his next Cytopoint injection and it also helps me gauge when I need to get him more activity to keep his weight normalized!”

Molly McAllister, DVM, MPH

Chief Medical Officer, Banfield Pet Hospital

“My 3 year old German shorthaired pointer, Sandy gained several pounds. Her Whistle tracker showed that she did half her normal mileage and wasn’t burning as many calories. Looking at the objective data from her activity, a ligament injury was highly likely. An exam confirmed. Her signs before the surgery were incredibly subtle but her Whistle data told a different story.”
