Spencer had another accident in the house several nights ago & was still obsessively licking himself. Back to the vet we went. This time they took an x-ray, to check for bladder/kidney stones. He has a very small bladder stone, but the vet did not seem to think it was an issue. She did see some narrowing in his spinal cord, she believes due to natural aging. His spinal arthritis has also worsened. She admitted there was no clear-cut reason for the urination in the house, but thought possibly the narrowing in the spinal cord might be causing a nerve that controls the bladder to be compressed. She prescribed cystolamine, a medicine to help with bladder control. He has taken it the past 3 nights with no accidents, only some minor leakage one night. She seems to think all his licking was due to his instinct to clean himself when he leaks urine, but then in turn the licking stimulates more urine to leak. He does seem to be licking less since being on the medicine. Anyone have any experience with incontinent dogs or any experience with this medicine? She wants me to try the medicine for 2 weeks to see if it works & then we'll go from there. I'm hoping it works. I'd really hate to have to confine him at night.
