WELL....i AM a COE Rottie Breeder. Have been breeding for 25 years, with lots of AKC/Canadian Conformation and obedience titles to my credit. We are also well known for long lived healthy Rotts (almost unheard of now a days).
With that said...i do NOT rescue Rotties for several reasons. Not the least of which is the inherent danger to my family taking in dogs of unknown history. It's not worth it to me or my other dogs in terms of disease and ill temperament. Many Rotties in rescue are there for a reason as i can attest too, with nerve damage to both hands as a result of a severe, unprovoked bite, from a dog that gave no warning. He had been taught NOT to growl, hence the BITE, with no growl (warning). His "new rescuers" had brought him to me for evaluation, because he was (unbeknownst to me of course) biting THEM. The poor placement, training and socialzation equalled the Blue juice for him, through no fault of his own.
What I DO offer, is assistance with placement, if i can. I offer referrals if possible and only in certain circumstances (where i can gather enough info on the dog that i feel it's placement is through unfortunate circumstances, often beyond the control of the family).
I always ask folks who contact me with emails or phone calls professing they HAVE to get the dog out NOW or else....is this question: "Did you contact the breeder?" that simple questions drives my point home. Ethical, caring breeders bear a cradle to grave responsibility for what they produce.
The countless hours i have spent with people coaching them in the "right" way, very often ends with another phone call...."Um...hey...i bought puppy X from breeder Z, because it was ONLY X dollars and i really only want a "pet" anyways....but while i have you on the phone...puppy-puppy is biting my kids and drawing blood, or puppy-puppy was just diagnosed with severe HD or Demodectic mange, or Parvo...whatever..... what should i do?....can you help me?"
NO. Ask your "breeder". Why should we be ultimately resposible for the actions of others, when we can only control our own?
Climbing off my soapbox now....
In reading your signature line, you say "support" rescue...what exactly does that mean?
