Why is my dog constantly licking his red, sore penis with discharge?

Causes of licking the prepuce/penis area could be a urinary tract infection, crystals in the urine, stones in the urinary tract, or trauma to the area. It is important that you make an appointment to have Mako seen by your veterinarian as soon as you can to help determine the cause of his behaviour and to start treatment. If you notice him straining to urinate/unable to produce urine, this is a medical emergency and he should be seen by a vet immediately. I recommend you put an e-collar (cone) on him to help prevent him from biting/licking at the area as this may help reduce the risk of infection

Hi there. Thank you for posting the picture of Larry. It is actually very helpful. The area just in front of the penis as well as the inguinal area both look inflamed. I suspect the has a skin infection. This could be bacterial or fungal, or both. I would encourage you to have him evaluated by a veterinarian soon. They will likely recommend oral medications such and antibiotics and maybe antifungal medications as well as possibly a special shampoo to help clear up the infection. Sometimes these skin infections can take weeks to resolve. Often they are secondary to skin allergies. Best of luck and thank you for using Pet Coach.

Dylan's prepuce is very swollen and appears infected and shows a lesion. This can happen if he licks it a lot, bacterial infection can cause that and also a type of venereal cancer called Canine transmissible venereal tumor or Sticker sarcoma. Here is information about Canine transmissible tumors: https://vcahospitals.com/know-your-pet/transmissible-venereal-tumor This is rather rare in neutered males, however it needs to be ruled out. I suggest you make and appointment with your vet to have your dog's external genitalia examined. Depending on the findings your vet may prescribe antibiotics or an ointment for treatment of the condition. In the meantime, if you have an e-collar, put it on Dylan to keep him from licking, as this will only make it worse.

Usually penile discharge is due to an infection of the penile tissue itself known as balanitis. His constant licking will be leading to more inflammation. Your vet should be able to treat this easily with antibiotics and it would be good to have him wear a cone to stop the licking whilst it heals.

Yes, I would be concerned about Guapo in that this redness and discharge can indicate an infection. From the pictures, it look like the discharge could be pus. He could have an infection of the prepuce (the penile sheath), or he could have a UTI or bladder stones causing these symptoms. I would gently wipe the area with warm water on a soft cloth, and have him seen by a vet. The vet can examine him and diagnose what is causing this redness and discharge so he can be treated. Taking him into a vet today would be best if possible. When dogs have infections, they can lick the area because it's uncomfortable to them, but licking it will make it worse. I would put an Ecollar on him if you notice him licking his penis area. You can make one at home or you can buy one at a pet shop. Good luck, I hope this helps! http://dogsaholic.com/care/homemade-dog-cone.html

Without pictures it is difficult to say what this is for sure. This could be smegma, which is the normal yellow discharge that is seen coming from a male dog's prepuce, which is a natural lubricant for the penis inside the prepuce. If it is not liquid at the prepuce you are seeing and a pustule, this could be infectious. If you could provide photos and post again it may help determine what this is exactly. Otherwise, a veterinarian should take a look at this so that the most appropriate diagnostic and treatment recommendations can be made. I hope this helps! Please let me know if you have any other questions or concerns and I would be more than happy to help you further.

Max's penis is definitely irritated. Most importantly, make sure he is able to urinate normally. If he is straining to urinate or unable to produce urine or urinating blood , he may have a blocked bladder, and this is an emergency. Otherwise, continue to monitor him for signs of pain or discomfort. It may be a good idea to have a urine sample tested by your veterinarian to make sure he doesn't have a urinary tract infection or evidence of bladder stones.
