I cannot see the penis of your dog very well as it is very blurry. This could be the normal shape of the bulbus of the penis which is a physiological swellbody to lock the penis in the vagina during mating, but also a problem. However I would need a sharp picture to see that. Maybe you can upload a better picture and we can help you with your query.
