I realize that lots of people do multiple dog sports with their dogs. My question was more specific to IPO and whether or not people regularly cross over into other dog sports with a dog that is used for bite work.
For example, I know that IPO dogs cannot also do SAR. I didn’t know if there was a “common practice” when it comes to agility.
I’m pretending, for now, that time and resources aren’t going to be an issue. Time will tell, of course.
As far as suitability, that will be up to his trainers to evaluate. Both of his parents are titled IPO3, and he doesn’t have any physical abnormalities as of now that would preclude him from doing anything. That said, he only has “moderate” drive, so I don’t know if he’ll be drivey enough to title in Schutzhund.
We did intentionally get a puppy with only moderate drive. After discussions with his breeder, I knew that a super high drive puppy would not suit our lifestyle, so he matched us with one of the mellower pups of the litter.
All of this would be strictly for fun. Titling would be cool, but isn’t a necessary part of my life. I just want to have fun with my dog.[/QUOTE]
It’s a common misconception that you NEED a high drive dog to do well in IPO.
(Personal pet peeve is people breeding off the chain drivey dogs/can’t settle/must be outdoor kenneled/pretty much unable to be around people and relax types) and whose high drive can often mask poor nerves and other issues - seems to be more of a problem with Malinois but it’s becoming an issue in German Shepherds sadly (the breed was never meant to be like that but that’s a soapbox for another day).
Iron von den Wolfen last years WUSV Champion with Debbie Zappia is a MEDIUM drive dog. What he is, is insanely trainable and obedient and that is worth more than a high drive type.
So you CAN have medium/moderate drives AND be successful in the sport 
Having ‘enough’ drive is enough (I like drive building with dogs, but for some people it saps the fun out of IPO).
I do know of several people who do agility AND IPO with their dogs (more than just ‘club’ level too - couple National competitors) - will you be at Nationals in both sports? No. But it’s fun to do both and expand your skillsets as a trainer.
My breeder has a breeding bitch that does IPO and Flyball. One of her young females from a breeding is doing agility AND IPO (will be going for her IPO1 in a few weeks).
If I hadn’t discovered IPO and gotten hooked I would have done agility.
Unfortunately I discovered IPO and am OBSESSED. 
Waiting on my next competition dog to be bred and the puppy fever is real.
