I think six weeks is way to young. They are still learning social skills at that point. Some states say you have to keep them until 8 weeks.

I would never let a puppy go before 8 weeks shame on that vet!

Here is some info:
The answer to this question, like just about any question in law, depends on where you live. Approximately fifteen states have laws that state how old a puppy must be before it is offered for sale or adopted out to an owner. Three additional states have administrative regulations that give a minimum age for puppy sales. Of those states with laws, thirteen require that a puppy be at least eight weeks old before being offered for sale. Of the remaining five states, two states (Pennsylvania and Virginia) mandate that a puppy be at least seven weeks old and one state (Nebraska) requires that a puppy reaches six weeks. Two states do not speak to a definitive age; rather, these two states (Illinois and Nevada) make it unlawful for to sell a puppy who has not been weaned from his or her mother.
