Hello Massimo,
sorry about my english

. I sell puppies, when they are 42days old, it is after first vaccination. Some breeders sell puppies from 5 weeks, without vaccination

. But sometimes I have puppies in the kennel longer time. For example now: I have two puppies 2,5 months old. But the puppies have perfect socialisation. They go every day for a walk on the leash. To the streets. They can see all in the city. I think, it is not problem for them. But in the other kennels the puppies can be on the garden, only.

They don´t see strange people, other dogs, cars,... I think, it is problem of big kennels, for example in the Italy

. theese puppies will be shy in the future. There is age - two months problem. Hanka ( kennel od Uhoste)
