My shih-tzu bichon mix seems to have two sets of testicles, one set in the sack and one set higher on the penis shaft. Is this possible>

Hi there.

Those are not testicles you are seeing. There is a structure there called the bulbous glandis. It looks like two big bumps on either side of the penis. The function of this structure is that it swells when he is mating with a female. The female clamps down on this structure and thats how they get "tied" during breeding.

So no, your dog isn't weird or anything. It's a normal structure.Laughing

I hope this information helps you out. Let me know if I can help you further.

This helps except he is not mating when I see this.

HI there. I'm glad it helps.

He doesn't have to be mating when you see it. I see it on my dog when he's at rest lying on his side. It's always there. Sometimes it's bigger, sometimes it's smaller and sometimes you can't see it at all. It's a normal thing and nothing to worry about.

Take care!
