Short runs on concrete for a pup

My new pup is absolutely nuts every second she is awake, I am having trouble getting her enough exercise. I work her on the flirt pole (try to keep her back feet on the ground but she always ends up in the air anyways....proving to be super athletic) play indoor fetch and do everything I can to keep her active and get her tired. This is an indoor dog, although she does close to a couple of hours on her backyard tie out each day.

I walk her but have severe plantar fasciitis so am limited there. If I had access to water I would have her swim but I don't. 3 days ago (after she turned 4 months old) I started taking her for very short runs on the bike. We started at 100 yards and now do 200 yards. I peddle very slowly and she is always out ahead of me, usually wanting to go faster. Conventional wisdom is that any running on concrete before 8 months can lead to joint problems, but these are not conventional dogs. I did the same w/ my last dogs and they never developed joint problems.

I find that if I do flirt pole, fetch, walk, and a 200 yard run then doing all will get her fairly tired. She goes absolutely nuts over the flirt pole already so she already is doing what she should not.

I found a good scientific article, and the article concludes that Pit bulls are much, much more resistant to joint damage than other dogs, but still am concerned about any concrete impact. Has anyone had joint problems from short runs on concrete w/ young dogs?

Here is the article documenting the robustness of Pit Bull joints Functional-trade-offs-in-the-limb-bones-of-dogs

Keep in mind, the run is only 200 yards and slower than what she wants. Of course I check her pads every time.

 

Of course, tug of war can't happen until 6 months.

 

Excerpt rom the article:

We wondered if similar differences might exist within limb bones of animals specialized for running versusthose specialized for fighting. Although the limb bones of most species are unlikely to experience the level of impact loads that deer antlers are subjected to during fighting, many mammalian species fight by striking and grappling with their forelimbs. Fighting can be expected to load limb bones with maximal muscle moments and in directions that are highly variable and unpredictable. Furthermore, during grappling, bending and torsional moments on limb bones induced by an opponent might exceed those that the animal's own muscles could produce. Limbs are also targets of bites during fighting. Biting could fracture limb bones outright or induce failure from bending or torsion as the two animals struggle. Indeed,fractures of bones do occur when dogs fight. In a survey of 284 bone fractures in dogs admitted to a metropolitan small animal hospital over a 2-year period,fights were the third most frequent cause of fracture and accounted for 14% of the bone fractures that were due to causes other than encounters with automobiles, human feet and slamming doors(Phillips, 1979; Cook et al., 1997). Dog attacks also produce bone fractures in humans, occurring at a frequency of 0.4% of the nonfatal dog attack-related injuries treated in USA hospital emergency departments in 2001 (Gilchrist et al.,2003). By contrast, other than in racing greyhounds (discussed below), we were unable to find reference to failure of limb bones during running in dogs. Thus, there is reason to suspect that selection for fighting ability might result in limb bones that are more resistant to failure than the bones of animals specialized for running.
