When breeding a collie, or any dog, it should never be about profit. Instead every litter that is bred should ultimately be a labor of love. Most dog breeders if they breed responsibly and carefully raise their puppies to be healthy and well-socialized, will be lucky to break even. When I chose to breed my collie, I did so cautiously, with concern for choosing the perfect stud dog. Knowing I would not have many litters, I chose to follow some advice I once read, "breed each litter as if it were going to be your only litter." I did the research, I studied pedigrees, I evaluated temperaments, and I looked at the puppies the dogs were producing. Then I took a leap of faith and bred the litter. And it was a leap of faith, because there are no guarantees in dog breeding.
The evening the puppies were born I sat terrified, waiting anxiously for each puppy to be born. After the first pup was born, it was a long wait for the second puppy to arrive. And as the minutes passed, my apprehension grew until I began tearfully pacing, fearing the worst. Fortunately, the second puppy arrived, large and healthy, followed almost immediately by his sister. Finally, as the evening wore on, the fourth and final puppy arrived. The fear and worry I felt waiting for those four puppies to be born was overwhelming, I don't know how others can do this multiple times, over 20, 30 or even 50 years. But without all those reputable breeders of the past, I wouldn't have my own beloved collies. Breeding a litter should never be done without careful consideration of exactly what you are hoping to produce. And to do that, to know where you want to go with your line of collies, you have to educate yourself on where your collies came from - by looking to the past.
