Dudley has demodectic mange also. He is 10 years old and has had it all of his life. It is no reason to put a dog down. You can get special medicated shampoo and give the dog bathes and then give him antibiotics when he breaks out...it shouldn't cost you 200 dollars...I would check around. If you think that you might put him down, please don't, Mike and I will take him since we already deal with Dudley.

Good luck and I hope everything works out for the best.
