Sittting On Stomach Pin My Dog Has Been Walking And Sittting With His Right Ear Sort Of Favoring The Ground.?

My dog has been walking and sittting with his right ear sort of favoring the ground.? - sittting on stomach pin

On a walk or sitting in the head and not on the right side of his face and head area are the driving force in the vicinity of the earth as a decline. and it is out of balance
a little.
Is there an infection or something else?
Is there a home remedy?

Thanks
