Have a friend who has a kennel license here in PA. Just down the road from me. She raises Shelties and Japanese Chins.
The new dog law here in PA requires minimum cage size for a dog based on its length and height. Length is from nose tip to tail tip. Height includes the top of the ears. Based on these measurements, a certain # of square feet of space must be provided for the enclosure. Based on this new law (last year), she now has to provide a crate for her 15# Sheltie that is the size normally used for an Akita.
Can you imagine the size required for a Lab or Golden? Remember, you have to include the tail. Can you imagine the increased space needed for what may seem to be reasonably sized crates and kennels now.
Additionally, all crates and fencing must not have any visible rust. Chain link will usually have some rust after a period of time.
And raising puppies ... to meet the enclosure sizes, she pulled some old x-pens out of her garage & set them up. She was also told that if she wanted to put two of the Shelties in that pen it had to be large enough to meet the square footage requirements for the two dogs.
Her final conclusion is that she will sell off her Chins, so she can accommodate the Shelties.
Things are not much better in surrounding states. The puppy mills have been used as a weapon against hobby breeders as well. Time may come when pure-bred dogs are a lot more expensive than they are now.
