What do normal dog testicles look like? When should I see a vet?

It certainly looks like your dog has completely normal and healthy testicles, as far as I can possibly say without palpating them. It is quite normal that one testicle is a little bit bigger than the other. The skin looks normally pale pink, ie not red and inflamed, and the scrotum appears to have normal hair. So, I do not think you have to worry about Bear's testicles being abnormal or diseased.

This is may be normal but it's impossible to know without palpating the area. Palpate both testicles at the same time. If they feel like they are different sizes, different temperatures, different shapes or seem painful, I recommend to have him examined by his veterinarian. I hope this helps.

It is really hard to tell by pictures if skin is normal. I think based on the photo that Ludo does have normal testicles. The testicles can have some pigment on them. However at anytime Ludo is not acting normal, itching, abnormal urination or not eating I would recommend taking him to a vet to have them checked in person. hope that helps

Thank you for submitting your question regarding Bear. No, it is not possible to know if a mass is cancerous or not just by looking at it. The testicles would need to be removed and the suspicious one submitted to a laboratory. I hope this information helps!

What you may be seeing is his bulbus glandis. They are two glands located at the base of the penis on both sides. They function during mating to effect the tie while mounting a female. This is normal and likely no cause for concern. The pigmentation of his scrotum may also be normal. You can have him seen by your veterinarian to discuss any concerns regarding either.

Thank you for submitting your question regarding Beau. This is likely just a normal part of his anatomy. You may be noticing a portion of the testicle known as the epididymis. It is best to have him seen by his veterinarian though to know for sure. I hope this information helps!

Yes, your dog's testicles should be approximately the same size. One can be a tiny bit smaller, but there should not be a huge difference. Your dog needs to be seen by a veterinarian as he could have a testicular tumor, a testicular torsion, an abscess or orchitis or brucellosis. Please take him to a vet ASAP.
