My cross lurcher/terrier dog is nearly 2 years old.  We got her speyed when she was about 6 months old.  We noticed that she started peeing in her sleep and then dribbling when she was sitting down so we went to the vets who put her on tablets for urine infection.  Went away and came back a day after they finished.  So he got us to give in a urine sample and he then gave us stronger tablets which seemed to work.  it then happened again after we got her back from the kennels and realised it was when she came home from kennels the time before it was happening. so the second time it happened we did the urine test but it came back fine.  he said if it keeps happening to let him know. but then it stopped. this was a few months ago. she has been fine since until today.  we had her at the beach tonight and she was in the sea. she came back and drank loads and then has been weeing when she is resting.
any ideas?

Hi when they get spayed they can have bladder trouble where they can't hold they're wee, so it's probably due to her operation.

Warm regards Susan
