So many things wrong here that I don't even know where to begin.
Here is an anonymous, naive, 23 year old novice dog owner with a poorly written (free) website and a not very well thought out idea and subsequent plan. She is probably a very nice, sincere young lady, but that doesn't mean a thing in this endeavor.
I had cockers in the 70's and 80's, and the many, many problems in that breed caused me to turn to Cavaliers in the late 80's. (And as many of you know, I've been blessed with nine healthy, long-living Cavaliers in the past 20 years.) There are so many more problems in cocker spaniels than were covered in "requirements" for use as breeding stock in this plan. Does this person know anything about inherited DCM in cocker spaniels? Does this person know what DCM even is?? Who passes judgment on the temperament of the stock - only the owner? Why the choice of cockers and paps? Just because one might "guess" that offspring MIGHT look like a (poorly bred) Cavalier......or not. Why would I want a cocker/pap mix? The end result may be some "new" breed (or not) but it's not going to be a Cavalier. Temperament certainly will not be "Cavalier." Why would the owners/breeders of good cocker/pap breeding stock want to cross their animals with another breed? They don't care anything about re-creating Cavaliers. Likely the only people willing to participate would be pet owners with dubious quality animals.
It's as if I decided that humans should explore outer space and I started a project with no knowledge, expertise or background in physics, aerospace engineering, etc. (Not a great analogy, but you get the idea.) No one could even check my credentials because I only give my first name on my free website??!!
If anyone is going to "re-create" the Cavalier, I strongly suspect that it will be experienced breeders.
My intention is not to criticize this unknown person, but to criticize the plan and methodology. I just do not see any merit here at all. It's just like all of the reasoning we hear about designer dogs being more healthy which we know isn't valid. By the way, did you see the advertising on this site for Cavachons, etc.? (On a free site you must accept the advertising.) How is this helping the Cavalier breed?
If I want a chance at having a relatively healthy, long-living Cavalier, I know what to do and who to contact. Never a 100% guarantee, but I've been around long enough and done my homework. I would also consider other breeds - but I wouldn't consider a cocker or a pap!
With all sincerity,
Pat
