Thank you all for your comments and pointers. Here's the thing, at home I have a deck that spans the entire width of the house, and it's two tiered, with a set of two steps between the upper and lower sections. Since she was about 6 months old, a favorite game of hers, when she got the zoomies, was to race from one level to the other as I sat on the steps between levels, and she jumps over me, clearing me easily. Then she'll race around again and repeat several times. So she's literally jumping 3 feet in the air and leaving the ground for around 8-10 ft. She's never shown any discomfort or anything afterward, and it's a game that she devised, not I. So, as part of the obstacles I have access to, there is one tunnel that is only about 4 ft long, but it's maybe 2 1/2 or even 3 ft in diameter. She's been jumping over that for awhile now. First letting her body sort of just roll over it, not jumping hard enough to clear it. Lately she's been jumping higher and landing on all four feet on top of this barrel then sort of hoping off the other side. So she's already jumping way beyond what seems to be recommended...And again, she does this stuff for fun, not because I'm directing her to do it.
She is large though, 27.5" at the withers, and 75+ lbs, so I don't want to push her beyond her limits. But honestly, if I asked her to jump over stuff that was the height of her hocks, she'd get bored and wonder if I was crazy!
At any rate, I think I'll work on building muscle without focusing on jumps for now, as it seems that would be the safe route. This is a dog though, that I believe could easily clear a four foot jump currently...And probably will be jumping through much higher windows in the future😊
Pirates Lair: loved the last video on your pup's reaction to 9mm gunfire. My pup is equally non-plussed. I had her out walking through crowds during the 4th of July at 6 months, and firecrackers and other fireworks didn't phase her at all😊
