My dog has a knot on his penis base & very yellow urine. What's wrong?

If the lumps are at the base of his penis, it could be his "bulbus glandis". Also known as the "knot", these glands become pronounced during mating or excitement and are quite normal. If the lumps are not at the base, have Max examined by your vet to determine cause.

Hi there! Thanks for using PerCoach! This is certainly concerning for a focal infection of the prepuce with even possibly a concurrent urinary tract infection. I recommend that you have him evaluated by your veterinarian for further assessment and treatment based on findings. Good luck!

These knots sound like a normal structure change for a sexually maturing male dog. If You can possibly provide a picture then I would be able to tell you with more accuracy. Signs to watch out for, that indicate an infection include; Discharge Swelling of the prepuce or penis Redness Foul odor Pain Difficulties with urination Penis which protrudes and cannot return to prepuce If you notice any of these signs start by placing an e-collar to prevent Chewy form licking he area and potentially causing damage or introducing infection. Then schedule an appointment with your veterinarian for pain relief medication, anribiotics, and antiinflammatory medictaions.

There is gland at the base of their penis that can get enlarged when excited and not fixed. If his penis was out and this gland was enlarged with blood he may have gotten too excited which caused the increased blood flow to the area. If this is the case the swelling and blood should completely be gone with his penis back in within 30 minutes. If it is not then I would take him to a vet for further treatment

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.

I would have your dog checked for a urinary tract infection. These types of infection can cause a change in the color and consistency of the urine. It is normal for male, intact dogs to have some discharge from the prepuce but if the urine itself is abnormal he needs to be evaluated by your vet and have his urine checked.

There appears to be some major inflammation at the tip of the penis, most likely from an injury or excessive licking. My best recommendation to you would be to have Taco examined by your veterinarian. I would bring a urine sample to he appointment if you are able to catch one. Taco will likely need antibiotics and anti-inflammatory drugs to get he penis back to normal. I hope this helps. Thanks for using Petco Pet Education Center, formerly Petcoach. Best of luck.
