Hi-ya - really interested in the responses to this question. In the short time that I have been breeding cocker's not only have I had CP but also fading puppies (this is the most heart breaking thing in the world to go through) after some long & tearful conversations with some really amazing animal lovers and gifted individuals.
I make sure that my bitches have both vaccines against Herpes and I feed the folic acid tablets and since this regime I have had two litters one of 3 pups and the other of 7 and we had no cp's or faders. The important thing is to always care for your bitch ensuring that the food you feed is suitable for a bitch in pup. I can only say from my experiences that any litters I plan in the future will be including both of the formentioned supplements. Good luck
