Re: Help! My dog's become incontinent after being castrated.

I have no personal experience, but found this info and web link. Don't know that it is helpful, but it seems to indicate a need for hormonal re-balancing, such as additional testosterone for males. I hope he gets better fast.

Here is the link and I copied one of the more appropriate Q & A's.

Incontinence after neuter

Q: I am in search of solutions to two problems that I am having with my 10 month old male pug "Pepper Boy". He is having a urine leak from his penis since approx. 1 month after he was neutered at 8 months. My local Vet. gave him a 2 week supply of Antibiotics but this did not clear up the problem. The second problem is a bald spot that has developed on his shoulder. We have tried various creams but these have not helped. The Vet. thinks it is a fungus but can not rid him of it. Any help you could provide in solving these problems would be greatly appreciated.

A: I guess I would be suspicious of hormonally based incontinence in a dog that developed urine leakage after neutering. Usually this will not occur this quickly and it isn't a common problem in male dogs but it just seems like a reasonable possibility once infection seems unlikely (the reason for the Antibiotic treatment first). It is usually responsive to treatment with testosterone replacement and sometimes only a couple of injections are necessary to stave off the problem for long periods. It might be a good idea to take bladder X-rays to rule out bladder stones and consider a general chemistry panel to rule out causes of increased urination before attempting incontinence treatments.

If your vet has taken skin scrapings from the sore and not found parasites then I have no other good suggestions for diagnosing this problem other than considering a skin biopsy if it won't clear up. They can be very helpful in difficult cases of skin disease.
