My dog’s trainer told us that 8-10 weeks is a period of heightened insecurity and does not recommend changing their home at that time.
Bruno came home at almost 12 weeks and knew sit/crate training and was well socialized with puppies and adult dogs. The breeder’s early work was incredibly helpful for us![/QUOTE]
One of the first fear periods is around 8 weeks, but that will happen if the puppy is still at home or not.
That one of those periods happens doesn’t mean we can’t bring new things to the puppy at that time, as the first studies of Pfaffenberg assumed.
Later those assumptions were challenged.
