depends on how you are keeping them. are they on concrete or small quarters. I noticed when I had mine on diamond they would crap nasty half solid yellow crap and crap alot. when I got away from the high corn as the main ingrident the crap less and more solid for easy clean up.
Stakes with tie outs on dirt. I have to shovel every other day. Sometimes a pile or two per dog, every other day is 4-5 piles and the solidity is in consistant
