Why is my senior male dog's penis sensitive from wearing diapers?

Poor guy. Scruffy has likely caused some trauma to his penis, leading to inflammation and this can lead to the penis getting stuck outside the sheath, strangulation of the penis, and even infection. I am unsure exactly how the penis currently looks, but the treatment is dependent on its current condition. If it is stuck outside the sheath then the vet needs to treat this by doing a sugar pack on the penis, or similar method to reduce the inflammation enough to replace the penis back inside the sheath. Also KY jelly is often used to facilitate this. If infection is present then oral antibiotics along with a copious sterile flush (i.e. chlorhexidine solution 3% diluted) of the penis is needed. Pet friendly NSAIDS (i.e. Meloxicam, Rimadyl) are also often need to reduce inflammation and provide comfort.

Unfortunately the only thing that will prevent this is to take him outside often and/or change his pee pad/diapers regularly and often. Shave the hair around the penis and on his belly in front of the penis and wash the area when he peed on it , at least twice daily, You need to dry the area well and then you can apply plenty of vaseline to keep the urine from coming into contact with the skin. If the inflammation is severe, if there are raw skin lesions or if you cannot completely remove the crusts and masses you will need to take him to a vet to examine him.

Most likely it was mild paraphimosis, which is condition when the penis does not come back to his normal position. It is very important to pull the skin back as soon as possible as trapped penis may have impared blood supply which may result in bad injury to the penis. It usually happens to young, not castrated dog and is a result of sexual excitement. If it happens to him in the future the best thing to do is to pull the skin back, or if it is not possible to apply a cold compress for a few minutes till the penis does go back.

The sores are likely from urine scalding. You need to wash the area that gets wet with urine with sudsy warm water, rinse it well and dry it well. Put vaseline everywhere where the urine would get on the skin. This will protect the skin. Ask your veterinarian whether Phenylpropanolamine will be a suitable medication for your dog's incontinence problem. The leaking can be caused by a UTI or by a lack of female hormones, or also old age bladder sphincter weakness. Your vet will give her a thorough exam and hopefully find the cause of the incontinence.

It is possible he is sensitive to shampoos or if the area was shaved he may have developed 'clipper rash' - very careful grooming in this area will be important to reduce the risk of it happening again. Keeping the cone on for a few days and gently bathing the area in cool water will help - I would not recommend any ointments or creams be applied as they may irritate the area further

Hi. Yes this is.most likley a harmless inicdent that probly wont happen again. I would recommend getting an evollar cone to have him wear for a.couple days to keep him from licking. I would also recommend placing a small amount of lube.or vaseline or ky jelly in the rip of that prepuce to lube it. If it gets worse at all get him in. Good luck

It sounds like he should be examined by a vet to determine the cause and treat. He could have an infection and may need an antibiotic to treat. Please schedule an appointment with your vet, especially since he seems to be in pain.
