Ty poops once a day, but if it's raining, not at all until I walk him and force him to go outside. Katie poops 1-2 times a day. 2 is usual, 1 makes me keep an even closer eye on her, but so far so good. No problems.
I believe part of pooping is based upon how well the food is used/digested in the dogs. When I cut out the high protein, higher fat, food with a lot of filler, I got less poop, and fewer needs to poop.
IMHO as a pet owner, I think monitoring food/water intake and daily output of your dog (urine and fecal) are essential. Paying attention to the little things can thwart larger problems in the future.
Sorry Wizard, I went beyond your request. I know you know all this $#!t (pun intended), but I rode on your coat tails to remind other pet owners how important monitoring daily habits of our B's can be.
Best wishes to you and Luny.
