The Question
“Dexter, my seven-year-old Yorkie cross, has been neutered, but he constantly licks himself and has a sexual reaction; his penis comes out, but doesn’t go all the way back in. And each time my husband has to help him by manually doing it. We just don’t know what to do.“ – Ruth

Hi Ruth,
What you’re describing is something we do see in neutered males, and it can feel worrying, especially when the penis does not return fully on its own. Even after neutering, some dogs retain learned sexual behaviors or respond to stimulation such as stress, excitement, or even skin irritation. However, frequent licking combined with the penis remaining exposed suggests there may also be a physical component, such as inflammation of the prepuce, irritation from allergies, or a condition called paraphimosis, where the penis cannot retract normally.
When your husband is manually helping, he is essentially providing first aid, but this should not be needed on a repeated basis. It is important not to rely on frequent manual repositioning alone, as the tissue can become dry, swollen, or irritated over time. Keeping the exposed tissue moist with a sterile, water-based lubricant can help protect it in the moment. At the same time, the persistent licking suggests there may be underlying irritation or discomfort that should be addressed at its source, whether related to the skin, infection, or anatomy. A veterinary examination is recommended so the underlying cause can be identified and treated appropriately.
In the meantime, preventing licking is helpful, as it can perpetuate the cycle, so using a soft protective collar temporarily can reduce further irritation. If at any point the penis remains out and becomes dark, swollen, or dry and cannot be gently repositioned, that becomes urgent because the tissue can lose blood supply. Addressing this early is the best way to keep Dexter comfortable and avoid complications, and most cases improve well once the underlying cause is identified and treated.
I hope this helps!
