First, never clean your dog's ears. This needs to be handled by a professional, since you could permanently hurt their hearing. Also, dogs ears are extremely sensitive. I think the amount of wax would depend on the dog. Dogs have big ears, so I could see a lot of wax coming out. However, the length in inches would depend a lot on how wide the wax is, since you can take a little wax and probably make a foot long wax rope from it (gross!).
