Is a black ball on my dog's penis shaft normal or a problem?

That could be fairly normal and could be possible (a picture would definitively help to be more precise and you can upload it by requesting a consultation ). I would suggest not squeeze them, as it could create inflammation and eventually it could get infected. Monitor it and keep the area clean for the next 3-4 days.

There is no picture attached to your post, so I can't say if his penis looks normal or not. There should be two bumps on the side of the shaft of the penis. They are called the bulbourethral glands, and they become enlarged when the dog is excited or aroused.

Thanks for the question again and the pictures. From what I can see on the images the penis looks normal, possibly slightly swollen but overall normal. It does not look like there is excessive discharge or signs of infections. If the penis is able to retract normally inside the prepuce, I would not be worried about it.

There is nothing abnormal appearing in that photo. There can be mucous in the sheath if there is an infection so you may need to clean that but the white portion in that photo does not appear abnormal

If what you're seeing looks like a symmetrical swelling near the base of his penis in front of the scrotum, what you see is likely the *bulbus glandis*. This structure is a normal part of the male dog's anatomy. The *bulbus glandis* swells during [mating](https://www.petcoach.co/article/anatomy-and-function-of-the-reproductive-system-in-dogs) which causes the dogs to tie or 'lock' together during the act. It may swell when the dog is excited, even in a neutered dog.

An abnormal shape to the penis could indicate inflammation or a tumor. I can’t tell from the photo if Wilie’s penis looks abnormal or not. This is a situation where a veterinarian visit is the best option. I recommend to have Willie examined by the veterinarian to get a better idea of what is going on. If the doctor is worried about a tumor, he may need an amputation. I hope this helps and please feel free to post any additional questions.

If you look at it closely, you should be able to see legs if it is a tick. I cannot tell because when I enlarge the photo it gets too blurry. The other options as to what it could be is a cyst or a tumor. I really think you need to have him to your vet for an exam. It is better to be safe than sorry. I can appreciate your financial constraints but maybe you can get assistance from one of these organizations: ( https://www.dogingtonpost.com/need-help-with-vet-bills-or-pet-food-there-are-resources-available/ ) Since you did not post your accurate location I cannot help you in finding a low cost vet clinic. You can a do a search online yourself or call your local Humane Society as they often know of the more affordable clinics in your specific area.
