Of course this own't applyn to coated breeds. In my breed you are generally very6 lucky to ahve them back into showable condition by the time the litter are 4 months and they are unlikely to be at peak condition until pups are near enough six months old.
Also a lot will depend on the breed. Most in my breed are made up at 3 to 5 years (dogs and bitches), but many later than that, and continue to win CCs to 10 years old or more.
I am taking my own young bitch out of the rting in teh Autumn for a litter at two years old (she has 1CC and 2RCCs) as I daren't wait any longer as her mother was a difficult bitch to persuade to accept a mate and she has also been having frequent sesons which a litter should hopefully stabilise.
It is more important to secure the next generation thatn make them up in my opinion.
You could continue camapigning a bitch to 5 years of age, then find it is too late to breed her and still nto ahve won that 3rd CC. I know many exhibits on 2CCs with fist fulls of RCCs athat have just not been lucky.
My own Champion bvitch was made up in one season when young, but I wanted to take her to the World show so waited until she was past 3 to try and mate her and failed. We did manage to get ehr mated and a litter Sept 03 when she was almost four (she had 7CCs by then).
She was fit and showable by Christmas, and has won another two CCs and another Group place since that litter, and is now taking a break for a second litter.
