What does bulbus glandis look like?

Answered by Michael Wilson

The bulbus glandis is a fascinating and unique anatomical structure found in male dogs. It is located on either side of the penis, and its appearance can vary depending on the individual dog and its current state.

When the dog is in a relaxed state, the bulbus glandis may not be very noticeable. It may appear as two small round lumps under the skin, almost like small marbles. However, when the dog becomes sexually aroused or during mating, the bulbus glandis undergoes a remarkable transformation.

As the dog becomes aroused, the penis sheath retracts, exposing the bulbus glandis. At this point, the bulbus glandis becomes engorged with blood, causing it to enlarge and become more prominent. It can almost resemble a small balloon or swollen sac attached to the base of the penis.

The size and shape of the bulbus glandis can vary among different breeds and individual dogs. In some cases, the bulbus glandis may be more pronounced and larger in size, while in others it may be smaller and less prominent.

It’s worth noting that the bulbus glandis can also undergo enlargement in certain situations. For example, in young dogs that are going through puberty, the bulbus glandis may be more noticeable as their reproductive system matures. Additionally, even neutered males can experience some degree of bulbus glandis enlargement due to hormonal changes.

The appearance of the bulbus glandis can vary, but it is generally characterized by two small round lumps when the dog is in a relaxed state, and a larger, engorged structure during sexual arousal or mating.
