Great post! I wish that I knew more about the bill to discuss it further but unfortunately I do not. From what I have read, the things that I have seen regarding puppy mills and the treatment or better lack there of should say to everyone that the current laws are not working. For Missouri to be attracting notorious millers from across the country to open up shop~that alone should be throwing up huge read flags.
Below are quoted from this link
Puppy mills are a $1,000,000,.000 a year business. Of course the millers are going to be against a bill that is going to make them put even a small portion of their profits back into their "livestock".
I am proud that IL has legislation regarding Pet Store and mills.
We are an agricultural based state and there has been no impact on our cows, horse, sheep, chickens that I have seen resulting from puppy mill legislation.

The Truth about Prop B - Alliance for Truth
Let's talk about the special interest puppy mill lobby. With a billion dollar a year business why wouldn't they have lobbyists to try to say voters opinion in their favor?
To me is seems pretty ridiculous to use the argument that cattle will be regulated by future bills. You do not stuff a cow into a crate or is that something that is done in cow mills
Dogs are domesticated animals and should be treated as such. There is no reason other than profit for someone to own 50 or more breeding bitches other than to make a profit. How do you take care of that many dogs without neglect? Puppy mills are know for selling sick and poorly bred dogs. There needs to be laws in place that address the current problems.
There is not enough space in rescues for all of the dogs being pumped out of the mills in this county. There are millions of dogs PTS every year in shelters all across this country. Millers see nothing wrong with bumping used of bitches at the shelters. The lucky ones find rescues. The unlucky are euthanized for lack of room. The least lucky disposed of.
How about Missouri's Dirty Dozen? 
Puppy mills that sell directly to the public are not required to be licensed. This loop hole has brought about the internet selling of puppies to unsuspecting buyers.
