Selling puppies and kittens before 8 weeks creates behavioral problems leading to abandonment.
Early separation of puppies and kittens from their mothers and littermates causes behavioral problems that result in abandonment and euthanasia. The pet industry routinely separates animals too early to maximize sales cycles. Puppies separated at 5-6 weeks show higher rates of aggression, fear, and separation anxiety. Buyers who receive too-young animals often lack the skills to address the resulting behavioral problems.
