Think of an athlete. They train run ,jump ect  They aren't practicing to the max. So if your dog is jumping 7" during practice or a little more. When its time to go they will jump much higher. And if they are doing it all the time they will develop muscle. Just take it slow. Moki has muscle all over. Doesn't feel like a little stick Yorkie. He goes though a course but gets plenty of rest. In between. Doesn't matter if the the jump is set at 7". He still jumping to clear 12"+ with ease.     |
