Hair falling out?

the problem yall are havin definately sounds like the red mange. i have had two dogs get it. and every pup in the litter eventually got it. one dog was a pit the other was a cur. it is hereditary (spelling?) from the mother only. the father cant pass it on. its not passed on by dna from what i understand. its passed on from the pregnancy and the mothers blood. i got this stuff from the vet that you put on the neck like you do flea and tick meds. they recommend three doses, one each month for three months. mine started growing the hair back within two weeks after the first dose. not all vets carry that med either. some dont even know about it. had to go to shreveport la to a vet off of north market. dont let the vet talk you into bringing the dog back weekly to get dipped. this stuff works way better and not to mention it will only cost you $20 per dose. the dipping will cost you a couple hundred and a lot of time. this stuff you do yourself.
