The bill was pulled from the Senate before a vote in July because it most likely would have been defeated at that time. It will be reintroduced in January with "revisions". The people who are behind this bill have an ultimate goal of eliminating all pet ownership in this country. They do not want to work with breeders and are unwilling to look at studies that recommend a course of action in line with what responsible breeders have been saying and doing all along, education of perspective buyer with life long support to help owners through the challenges of dog ownership.

This bill also will not effect the major source of impulse bought animals, out of state puppy mills that supply pet stores and out of state internet retailers who sell to anyone willing to submit payment.
It is also seems to ignore how many of the dogs that come into shelter do so without vaccinations, without ID of any kind, and no identifiable owner. If people are unwilling to spend $5-10 for low cost vaccinations and a simple tag ID, there is no way they are going to spend 10 times that amount to spay/neuter their pet. The only thing this bill would accomplish is to make responsible breeders criminals. It will have no effect on the people who are already breaking local laws.
