Excited to see the vet, a dog high-jumps 45 times in a row

I don't know what this veterinary hospital at Colorado State University does to incite such glee, but this dog, Endo, is jumping really high with excitement. Like above-the-counter high, causing the receptionist to break out in laughter. And the dog doesn't quit, with 45 good jumps in a row.
