I never thought about how often Chloe went until I read this. We have a winner. She has times she is going every 5 minutes(when wee wee pads are available) If I don't make the wee wee pad available, she holds it (maybe the scent makes her go more often?) She will pee on command as well (she fakes it to get a treat!) During the part of the day when she plays hard, she drinks more then goes more. During the part of the day we visit my daughter & her 2 fur-kids, Chloe gets a work out, drinks the most then P's the most. During the warmer weather she went more, after we play & run she drinks & goes more. She can hold it up to 12 hours in her crate but luckily doesn't have to wait that long often. However, she has a problem with hard B.M., which I am not sure is typical for a Yorkie??? You would think since she is so active, she would never have a hard B.M. or be constipated.
