Still lacking any scientific study here.

People claiming to be using scientific methods to sell a book isnr good evidence

Breeders dont get the experience of knowing what happens to their puppies in a scientifically controlled way by releasing them at x weeks and collecting bits and pieces of feedback from some of their owners. If they keep the dogs themselves thats not valid evidence either.


Again I reiterate that IF toy breeds were different from large breeds studies and professional opinion offered about dogs would need to make that distinction in their recommendations, in order to be quality advice. They dont on the issue of when to home a puppy. They do on other matters such as when different breeds reach adolescence, breeding age etc. There doesnt seem to be a widely held professional opinion that toy breeds need special treatment when it comes to the age they can leave the breeder.
