My grandfather raised beagles and coonhounds when I was a child.
I remember my grandpa having a smaller "dog lot" next to the bigger ones that housed his pack (one for boys, one for girls), and when he figured it was about time for a bitch to come in, he'd move her and the selected stud to the smaller lot. There, they'd stay together, day and night for about a month, until he was sure she'd come in, they'd bred, and she was expecting. Then he'd take the male out, and leave the bitch in there until she had the pups and they were weaned. There was rarely any vet visits, no special treatment, no temperature taking, no palpating, no monitoring for signs of labor. When he saw she was in labor, he'd check on her periodically to make sure things were progressing, but was a firm believer the dogs did better with little human interferance. And once the pups were weaned, she was added back to the pack.
Being a breeder myself, some 25 years later, I find it very interesting the differences in breeding "back in the day" and breeding today.
Like with most things, the whole process has changed, enhanced, become more complicated with the dog's best interest in mind.
I don't believe my modern day practices are necessarily better than those my grandfather practiced.... just different, taking into account that my dogs aren't "just dogs" to me, like his were to him and most people during his day. We know more today, have better access to things to make sure our dogs stay safe and healthy... and it's more acceptable to be overly cautious, I think.
Oh well, that was my random "back in the day" thought of today. I'm sure Paw is looking down at me from Heaven, rolling his eyes, as I gush and fuss over my girls, but I doubt he's surprised. He always said I was too soft-hearted.
