This is such a sad situation. It's just sad that this pet store still deals with these companies that send unhealthy dogs. Why can't more pet stores team up with rescues?

This is what I found for the California puppy lemon law:
California Law

This Law is the most hard on sellers of unhealthy dogs, but hobby breeders do not fall under its provisions except for the extremely active ones. As with the Florida Law, it is important to note that costs of testing to certify a dog unhealthy could double what a seller is obligated to refund to the purchaser. It is also important to note that this Law obligates the seller to cover 1½ times the purchase price of the dog in veterinary expenses should the purchaser elect to have the dog treated.

Pros: long period in which to find congenital or hereditary conditions

Update 4-6-2001 Pertains to anyone who sold, transferred, or given away two or more litters during the preceding calendar year.
See: AB 161

Cons: obligation to cover veterinary expenses above the purchase price of the dog may be considered punitive.

Applies to: any one who sells more than 50 dogs per year.
Contagious or Infectious Disease: 15 days
Congenital or Hereditary Defects: 1 year
Failure to Produced Advertised Registration Papers: yes, within 120 days, otherwise return dog for full refund or receive refund of 75% of purchase price if you keep the dog.
Replacement: yes, plus reimbursement for veterinary expenses related to certifying the dogs illness up to the price of the dog including sales tax.
Refund: yes, plus reimbursement for veterinary expenses related to certifying the dogs illness up to the price of the dog including sales tax.
Reimbursement of Veterinary Expenses to Treat Dog: yes, up to 150% of the purchase price of the dog plus sales tax.

So I wonder where we should even start here, if there is an opportunity to do anything. I know that most people who adopt from the pet store just can't bring themselves to trade it in for another one (which would be sick anyway also), because they've already fallen in love. If we got all the Pet Stop puppy owners to bring this puppy lemon law to the attention of the shop owner, do you think that would help? Also, I work in only 1 of the many vet offices in the area. Who knows how many Pet Stop puppies other hospitals in the area are getting!
