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.

    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!

Does my dogs testicles look normal
Yes, they appear fairly normal, but I would have to examine them closer and palpate them in order to ensure that everything is normal. If there is a concern, then it's best to have him examined by a vet. I hope that helps and all is well with Bear.

I have an 8 month beagle, he’s always had one ball a little bit bigger than the other. I went to the vet when he was 4 months and was told they might be a tumor because their was “tenderness” on the right side of his stomach and I might have to have
If his testicles are asymmetrical it may mean that something is wrong with one of them causing it to be larger or smaller than usual. It is also possible he could be cryptorchid if the smaller side is actually missing a testicle. For more clarity, you can have an ultrasound performed of his testicles and abdomen at a specialty hospital. Otherwise, neutering can help prevent the development of hernias, tumors, and unwanted behaviors.

I noticed that one of his testicles is a bit smaller than the other. It also looks a bit uneven I think. Should I be worried ?
It is not uncommon for a young dog to have uneven testicles. Typically, the smaller one will "catch up" in a few months. Monitor them and see your veterinarian if one is significantly larger or smaller in a month or two. If Meeko is to be neutered (recommended), it won't matter.

My dogs testicles are different sizes one is small the other is huge should I be worried, I have read online about testcle tumors could it be that.
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.

6week old puppy has one testicle a lot larger than the other is this dangerous. Should I sadly reject this puppy?
That's hard to say without being able to examine and monitor the testicles. It's possible this is congenital. If Digby is not a breeding dog, an undeveloped testicle is not a big concern (though I do recommend to have him neutered). A less common cause of a size difference is a torsion or infection. A veterinarian can get an idea of what is happening with an exam. I hope this helps.

I have a 2 years old male yellow labrador. His tasticles are black and big not swollen but his scrotum hangs a bit lower so it looks big. I dont have a vet near me, so is it normal?
The picture does not show anything concerning but I would continue to monitor for any sweliing or discomfort which may indicate a painful infection or assymetry which can indicate a tumour. Rapid increase in size can occur with scrotal hernias which although rare are a surgical emergency.

Can you please check the photo i am attaching of my dogs testicles.... Because i am not sure whether the skin and texture is ok or not
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

hello. sorry for graphic images! we are hoping you can provide some advice. Our 12 year old golden retreiver has one larger and one much smaller testicle and it is dark but now also seems to be red. They have always been quite big and saggy as he is
Thank you for submitting your question regarding your dog. He will need to see his veterinarian as it is abnormal for the testicles to be so different in size. He may be developing a growth on the larger one. He will likely need to be neutered and the testicle examined under the microscope. You want to ensure that he has developed testicular cancer. He could also have a benign growth, an infection or swelling resulting from a bruise from some sort of trauma. Either way though, he needs to be seen. I hope this information helps!

I have a pug one year old. One of his testicles looks very wierd like its pear shaped end, I am attaching picture. What can this be? Thank you so so much, Sandro
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.
