Would you knowingly expose your puppies to a known cancer-causing agent? Would you trust claims that this product is safe for use in puppies despite NO research supporting this claim?
Would you use it just because other breeders have done so for years despite increasing cancer rates in their breeds? Finally, would you routinely expose your puppies to this risk just so you would worry less about short-term concerns even if the long-term consequences might include higher risk of early and lifetime cancer? Most breeders would adamantly deny the use of any known cancer-causing product that has not been proven safe for puppies. Yet many do it regularly.
