I was first strongly opposed to this bill, but now I am in favor of it.

However, there are some serious serious flaws. For one, dogs and cats are entirely different species. Thus, they need different time frames. 4 months for a cat is vastly different from 4 months for a dog. A 4-month-old dog is sorely underdeveloped and I'm a strong believer that a well-balanced dog should not be fixed until s/he is physically mature.

Additionally, their prerequisites for an animal to remain intact/be allowed to breed is in dire need of editing. This...
(1) The owner demonstrates, by providing a copy of his or her
business license and federal and state tax number, or by other means,
as determined by the local entity authorized to issue permits, that
he or she is doing business and is licensed as a breeder by the local
jurisdiction or its authorized local animal control agency.
... gives even more freedom to BYBs and puppy mills.

And this...
(4) The dog is trained, or is
documented as having been appropriately trained and actively used by
law enforcement agencies for law enforcement and rescue activities.
... is completely arbitrary. What qualifies as trained?! As far as anybody is concerned, a simple "Sit" could mean that the dog is trained.

This bill is a good idea and it's heading in the right direction. However, I'm hoping someone will create a better bill to take its place.
