He was obviously a phenomenal dog and has shown to be a pretty good producer.
A friend of mine has a 5 1/2 month old pup that is Chavez x Code Blue bitch. This pup is the most trainable, intelligent pup I've ever seen. Whether he has the marking ability to make it in field trials remains to be seen.
More accurately, ask Kippy Swingle (aka Marion Stroud Swingle), Chavez's owner. There is a stud ad for Chena River Chavez in every issue of RFTN along with ads for Hawkeye's Red White and Blue and others owned by the same person. No website.
Marion Stroud Swingle's telephone number is 610-286-1913 and her fax number is 610-286-5669. She prefers not to receive email. RFTN is Retriever Field Trial News which is the "official" souce of information on AKC and CKC field trial and hunt test results as well as a standard source of information on competitive dogs, litters, rules, etc., etc. You can find out more at http://www.working-retriever.com/.
Before his death, Chavez earned over 150 all age points and, according to Good Dog info, has sired 31 FC/AFC/CFC/CAFC dogs. His progeny include two Canadian national champions and many dogs that have qualified for the US nationals.
I personally prefer his grandkids. I saw alot of Chavez kids back east and trained a number of them and was not fond of them. I found them to be average markers and difficult to train. Having said that I guess I just didn't get lucky enough to get the good ones. Many liked them. I think the best breeding of Chavez was to Dippomarsh Kerensa O Carronade. Those puppies were the best I've seen from him.
Of the many trainers that trained Chavez, Mosher did the best with him.
