Yes Lemon laws can be great if they are effective. How long is the time limit on those lemon laws. If it takes a Basenji 3 years or more to develop symptoms of Fanconi or any other disease then does that lemon law apply?
Is that breeder, or back yard breeder, or pet shop still going to be in business 3 years or more down the road?
What do lemon laws really do to stop irresponsible breeders from passing on genetic disorders from one generation to another as long as they are able to stay in business?
How many people are really going to complain?
Just think about how many people forget to mail in rebates. The companies issuing the rebates are counting on this. So if there is a time limit or restriction then for that irresponsible breeder, it might be worth the financial risk.
In my opinion, lemon laws just allow some financial recovery for the buyer if he or she catching things in time. It does not heal the heart over the loss of that animal, and it also may not be a big enough deterrent.
Just my thoughts
