two humps

It sounds like you might be seeing the hip bones. (?) If the hips protrude enough that you can see them, you might want to think of getting them wormed and feeding a higher calorie diet.

Let me know if you still have questions.

Thanks for you quick reply.. Though I don't think they are bones ... It feels kind of fleshy and my dogs are fat dogs (haha) I thought they might be fat deposits (one of my dogs has TWO of them under her arms).. But considering both dogs have these humps in the exact same spots, I ruled that out... I don't think I would be so concerned, but my brother even noticed them today (without me saying anything) and thought they were odd. Dunno - - I might just be paranoid,.. but is there any other possibilites of what they might be? If not, no biggie.! I feel a lot better knowing that you didn't reply with an OH MY GOSH< GET THEM TO THE DOCTOR IMMEDIATELY!!!! I won't rush to the vet, but will keep close observation!

Are they fat dogs? Or relatively thin?

they are overweight (or at least that's what everyone tells me!)

Dogs get fat in some of the strangest people. Just like with people, dogs will gather fat in certain places. (Like with us in our butt, thighs, hips, etc). In dogs, you will see weight gain in the chest, hips and around the tail.

You might just be seeing fat. :-) I know that sounds crazy but it's true.

If the masses move under your fingers, you may be dealing with fatty tumors. If you suspect this, I would see the vet to have a need aspiration done.

I hope this helps more!
