I am having my doubts on this.
Like someone has already said, Who sets the standards?
I am a little afraid that whoever does set the standards will go to far with them. I mean what kind of test are they thinking of giving potential dog owners?
You can't just have someone take a written test on the subject because that doesn't insure that they will follow through with what they write. And if they would take a test on actually handling a dog, how would you be able to know which person is a "good owner" or a "bad owner"?
Plus would the test cost money? All you would do then is weed out the real poor people and favor the rich. How much would a test cost? What would happen if the people started to raise costs because of their greed?
I think it's a good idea in theory, but I am not sure it would actually work.
