Recently Cricket has been stopping and dropping in the house. Trust me, this dog is on a routine, but out of the blue she has "marked" two spare bedrooms and the hallway in the last month or so. Could we have a bladder problem? If so, how would I know? No blood in her urine, no change in behavior. I'm telling you, this pup is a piece of work!! But aren't they all
any suggestions?

The first step I would take is to have urine checked for UTI. Leo had a UTI that took two rounds of 21-days antibiotics to clear up. So if it is UTI make sure you have the urine checked again after they finish the antibiotic just to make sure it is gone.
