My 10-year-old pincher during our morning walk will attempt to urinate about 6 times in a period of 1 hour. At first there is a normal stream with no blood.After she begins to squat and strain herself as though she need to deficate. She may emit a few droplets or none at all. Otherwise she seems to be full of energy but is hungry all the time. Normaly she eats once a day (for the last 10) I gave her Drontal and Frontline. She doesn't seem to have worms, ticks, or flees. Does she have a kidney problem or is this urinary behavior normal for her age?
