My 8-week-old puppy sits funny. Are his testicles normal?
Hello and welcome to Petco Pet Education Center, formerly Petcoach. Dogs can have their sex determined easily as males have a penis that lies along the mid-line of their stomach and girls have nothing in the area. If you roll him on his back, and see a lumpy structure down the middle of his stomach near his back legs, that is a penis. If this is completely smooth then he is a girl. Testicles can take time to decend, up to 6 months, so if they aren't down yet (and at this age would be very small) then this isn't a concern. I recommend just waiting. Puppies will sit in many different ways that can look funny, so it is likely just a puppy thing. If he is walking, running, and playing normally then I would just monitor him for now, and have the vet check it out in 4 weeks when you get his next set of vaccines. Best of luck with your new puppy.
