Q. My 10 month old pup doesn't use the "facilities" as much as she should be. She didn't go this morning, hasn't since. Eats/drinks regularly.
A. If she has been straining to pass feces or urine then you need to see your vet as soon as possible. Im assuming she has been urinating and it is just feces that she hasn't passed. If she is well in herself monitor her and see how she is in the morning. If she still hasn't passed anything by lunchtime tomorrow then give your vet a call. It can sometimes be caused by a diet change.
