At least once everyday, if its with only my dog he can go up to once every 4 or so hours, though after 3 times he's pretty much done for the day, but I often volunteer nights at m local shelter or invite active friends with dogs over so it can go up quite high, particularly on weekends, anywhere from 3-12 I'd say would be "regular" on a Saturday or Sunday where getting bred is all I do. I'm sure I've gotten more than that on days I've gone to the shelter and spent the night, but that's not average
