My dog come to me with these bald spots around 3 months age. My dog now 2 years old and spots still there. These spots same place both of legs sides. Everyone include veteriners says to me these spots source are sleeping in hard floor. And they are callus. But my dog sleeping soft floor. I using vasaline and some oils like a centaury, tea tree, coconut etc. But hairs don't come back on these spots. Skin very soft not hard and thick on these spots. I think they are not callus. But I dont know what are they and how to come back hairs on spots. There is no any itching, redness, acne, pimple, diffusion. Can help me anyone who experienced that before
