I've brought both puppies back to the breeders for visits and the pups seemed to remember their mothers and went nuts with excitement! The moms didn't seem to mind but definitely put the pups in their place, then everybody played just fine. I couldn't tell if the mom's recognized the puppies, but both pups definitely remembered the breeders, which makes sense since she sleeps in the kennel with the mothers and puppies. I think Uschi would have been happy to stay.
