I read the bill and it seems very reasonable.
The sportsman alliance link you provided makes some incorrect statements so please read the bill, don't take the word of the page author.
Basically it says if you leave your pup outdoors for an extended period of time it should have adequate shelter from extreme cold or heat. It also gives reasonable guidance to what a proper shelter should be [building materials, 3" off ground, overhang to prevent water from entering, windbreaks, and bedding material, common sense shit].
There are some exceptions for certain sport/hunting dogs in specific circumstances, but every year hundreds of dogs die due to neglect. If you properly look after yer pups, you got nothing to worry about, if you don't, maybe you shouldn't have dogs.
