I find that very young dogs that are spayed can get incontience. However it is not typical in older dogs no matter the method they are spayed. I would make sure a urine sample is checked for infection and crystals. If this is normal than it is possible she has developed incontience due to being spayed. Typically estrogen supplements helps the most prevent dribbling. Hope that helps

    Yes I have heard of spay incontinence, and this can happen in spayed dogs. No, it does not mean a botched spay. When a dog is spayed, the uterus and ovaries are taken out, which also removes the source of estrogen. It takes a certain amount of muscle strength in the urethra to prevent dribbling of urine. After a dog is spayed, these muscles weaken and it's thought the loss of estrogen contributes to the weakening over these muscles. This in turn can lead to spay incontinence. Not every spayed dog gets it, but about 20% will develop it within three years after being spayed. The good news is that it can be treated medically. Around 50-60% of dogs with spay incontinence respond to estrogen therapy, which works to increase the sensitivity of the closure receptors in the urethra. Given that all the blood work, x-rays, and ultrasound were normal, spay incontinence may be the likely cause of Harper Grace leaking urine. I would speak to the second vet to discuss estrogen therapy to see if that helps with her problem. Good luck, I hope this helps!
