Why this answer
A responsible breeder health-tests both parents, lets you meet the dam interacting with the pups in a clean home, knows each dog, provides records, uses a contract, and never places a puppy before 8 weeks. Red flags include leading with a cash deposit, no health documentation, always having puppies available, or refusing to show where the dogs live. Taking a puppy before 8 weeks is linked to later behavior problems.
When this doesn’t apply
- This is for buying from a breeder — adoption/shelter routes have their own process.
- Breeder laws vary by state; treat 8 weeks as the widely-set minimum.
What changes the answer
- Seeing the parents and the environment in person.
- Whether health testing and a contract are offered.
- The puppy's age at pickup — never under 8 weeks.

Common questions
How do I find an ethical breeder?
Look for health-tested parents, the dam present in a clean home, full records, a contract with a return clause, and no placement before 8 weeks. Walk away from cash-deposit-first sellers with no health docs.
Why does 8 weeks matter?
It's the minimum age to leave the mother and litter. Very early separation is linked to problem behaviors (fear, aggression, resource guarding), and most US states set an 8-week legal minimum.
