Doesn't this disrupt the early period in the litter? How does the mother dog respond? I would love to see studies on this. Can you post a link? Just very curious about this.
There are no studies on this, just our years of experience in raising puppies. All of the studies will tell you that the pups have not developed most of their senses yet....and if they are correct then no harm is being done because the pup is not aware of it.
When I was assisting in the raising of horses we did similar things within days of a foal being born, placing a blanket on their back, lifting their hooves like a farrier would do etc. Prepare and teach them very young and it becomes second nature to them....Less Stress.
From our experience, the pups are more aware of things than the "Experts" claim. I would want to know how many litters the Experts have raised, what breeds of dog and the pedigree's.
To start with, you need very good gentetics.
Both of these pups went through the same kind of training, both are now Award Winning Police dogs.
As for Mom, they usually sit back and enjoy the break.
A friend of ours who breeds Shelties has recently started implementing the same training with her new born shelties and is amazed at the difference.
It takes a great deal of work, patience and skills to do this properly, most breeders either don't care to put the time in or don't believe in it.
And that’s okay by us, we will keep doing what we do and having fun doing it.
