Oh Lord, demodex !! - Page 2

T&T pls read the sentence before the bit you quoted from Merck !
That is how wrong info gets spread around the Web - don't 'cherry pick'
your references.

Maybe the breeder was referring to the mites and not the immune system? Just a thought.

Oh, and one more thing--'red mange' IS the common term for demodectic mange; the other primary form of mange seen in dogs is scabies, also called sarcoptic mange and caused by the mite species sarcoptes.  Sarcoptic mange/scabies IS transmissible to humans. Demodectic/'red' mange is not, nor is it transmissible from dog to dog save for from dam to her pups within a day or two of their birth.

repeating hexe, I have seen it a few times after puppy changes homes. I have seen generalized only once, many years ago in a rescue. It was before ivomec and was pretty nasty and hard to cure.

A lot of people have NO idea about demodex (as seen above lol)... It is true that most dogs carry the mite but a healthy dog usually keeps them under control and have no signs and/or issues with it.  And yes the mites are often passed from mom to puppies, but it has nothing to do with care how good/bad the breeder is - again almost all dogs have them.  The problem comes up when a puppy has a weakened immune system and the mites start to get out of control.  It irks me to no end how most people treat demodex - they blast the pup with chemicals to kill the mites.  What do the chemcials also do? kill the immune system which is the problem to begin with!  Anyways, yes a poor immune system (and related problems) can be genetic and that can be passed on from either parent.  A poor immune system can also be caused by other things such as poor care, extreme stress, other health issues, or even less serious things such as a female coming into her first heat cycle, changing homes, an immature immune system, etc...  Yes it could be due to poor care, poor diet, kept in an unclean environment... however more times than not it has nothing to do with what the owner has done or is doing.  This is talking about localized demodex.  Generalized is a different story.  I did have a pup with localized once many years ago and did a ton of research on it at that time.  FWIW she was treated naturally and it went away on its own pretty quickly and she lived a long healthy life with no other issues.  

If I knew of a male who produced puppies "in several litters" who developed demodex, I would be concerned about the immune system he is passing on.  Not saying he should never be bred again without knowing all of the facts, but IMO it is something that should be taken into consideration.  

a questionhe brain trust for trust here. it's pretty well established that the mites transfer from dam to pups in the first few days. are there any treatments available to prevent this transfer.
it's been a few years and wondering if anything new has happened.
