Hello LMS and board
I will answer this from both aspescts, as a breeder and as someone who has experienced demo in dogs.
>>My first question to the breeders out >>there is, are the breeders responsible for >>hereditary problems?
Yes and no is the answer to this. When there are known genetic problems with available screening to aid in the elimination or at the very least minimising of a given genetic disorder/s then the breeder is indeed responsible to do everything in their power to avoid such problems.
One of the most basic tenets in breeding, amongst purists and responsible breeders is that one should only breed to improve the quality of whatever chosen breed. To NOT test for known genetic ailments would hardly be seen as breeding to improve as far as this little black duck is concerned.
Onto specifics though. Demodectic mange, in and of itself is NOT a genetic disorder. The demodex mange mite is in fact a part of the normal flora of a dogs skin i.e. all dogs have demodex on them. Your vet should of explained this to you.
In small colonies this mite is in fact harmless to the dog however when depressed immune system, whether due to disease, stress, injury or the like, is what allows the mites to proliferate. When they do start to grow in great numbers that is when problems with hair loss and secondary skin lesions occur.
So why then is the answer both yes and no?
Because a breeder may have control of some factors causing depressed immunity but have no say at all in other factors. One of the commonest causes of a depressed immunity in dogs is Canine Hypothyroidism. This is indeed a genetic disorder and one which can be screened for. Affected stock should not be bred from. This would be irresponsible.
But once a puppy is away from it's birth home a whole new lot of stressors can come into play which a breeder has no control of. Change of diet, overpowering children, missing littermates and momma, being a "yard dog" (very common), are some stressors that can cause unseen illness i.e. low immunity in a dog. In fact most times demodex rears it's head are in a puppies formative months.
>>If so, then am I out of line to ask for my >>money back?
That's a judgement call unfortunately. You can try and I know that if I couldn't get your pup cleared up for you then I'd refund your money. But not all are the same and in fact not all will see you as being entitled to a refund. It all depends on the factors which led to Max getting mange and why those breeders are breeding in the first place.
>>My last question is that if anyone has >>expirenced Demodex has your dog made a >>full recovery?
Yes on more than one occasion. It just depends, once again, on recognising the causitive factors of the mange outbreak. If it is stress related, most of the anti mange rinses coupled with removing the relevant stressor will work and the puppy/dog will fully recover as it settles. (It must be said now that dogs with mange from stress induced low immunity need not be excluded from breeding!)
Even if your puppy (anyone's puppy) has inherited Canine Hypothyroidism this is treatable through dosing with Oroxine or a similar thyroid hormone replacement. (These are the ones which must not be bred from!!)
It's not an easy issue and it is often poorly understood. But rest assured, mange mites on a dog ARE normal, in small colonies. It is not hereditary for them to be there. All dogs have them. It's the way they come to propogate that is relevant
