Hello, I was just wondering if it is normal for my 10-month-old puppy to have one testicle a bit larger than the other? I am very concerned. Thank you, Arden Martinez

Hi Arden! From the pictures, it doesn't look like one testicle is much bigger than the other. They should be approximately the same size, but one can be a bit bigger than the other. I hope this helps!
