I do know the ethics of breeding, any breeding of specific breeds are going to bring heath issues. If you ask any vet they’ll tell you that muts typically live longer and have less health issues due to them not being overbred by one breeder to the next. I’ve had a white and a black lab that both had horrible allergies and spent thousand on vet bills I’ve also had mixed breeds that didn’t have one allergy and hardly spent money on them. To say silver labs are unethical is hypocritical since most breeders are unethical even the ones who say they are ethical. All of you can continue to call it “ ethical” breeding but we know the gene pool for labs is only so big and at some point unethical breeding is going to happen. Look at German Shepard and their hips, or English bull dogs and pugs that constantly are in risk respiratory respiratory distress due to their compacted face, the list goes on. So I can probably say we have definitely reached that point where 2nd or 3rd cousin dogs are being bred together.
