I couldn't agree more. Good breeders will inform puppy owners, but good breeders are far and few between. Personally, I think the dangers from undersocialisation are actually greater than the dangers of taking out unvaccinated puppies. I take mine out before their vaccinations are complete. Initially they are carried, but it is SO important.

The other thing is that there seems to be a misunderstanding about what socialisation is. It is not just social interaction with other dogs and humans, although this is very important, but it is getting them used to different situations, towns, roads, cars, farm animals, horses etc. In fact, any situation that the may encounter during their life.
