I know, that I repeat myself, But I just get amazed every time, over how fast it goes. And not least how much/fast the puppies develop. Yes I've tried it few times, but … It's wonderful every time. From being small “Worms”, who can only smell their mother and stomach … then they are on less than 5 weeks small dogs! They run, jump, Bites, barking and already super skilled at asking to get out, when they need to “Pretzel”. Telling when you need to pee … there we are missing a little 😉 But … Some actually go to the door already now and whine – Also when they need to pee. Then it's lucky, that I am on leave and am at home with them from the time they are 4-8 weeks, and I really enjoy it.
