This trend of banning things will come up and bite the butt of people who support such things.
It does not stop with animals, it filters down into other aspects of everyones lives.
In Ontario for example
"Pit Bull" Ban
Smoking Ban
Ban on outdoor clotheslines in some areas (unattractive to neighbors
)How about environmentally friendly!
Going for a ban on trans fats
Going for a ban on junk food in schools
Considered banning leaf blowers
Upcoming ban ( in progress I believe) against incandescent light bulbs
But, they won't institute a ban against talking on cell phones in vehicles even though studies have shown that those who talk on cell phones in their car have the same lack of driving capabilities as a driver who has been drinking!
Other places are working towards other bans
Places in Manitoba I believe are banning plastic bags
One of the eastern provinces is trying to ban smoking on all municipal property (they have already banned smoking in cars carrying children) It's good not to smoke with kids in the car but does it really require a ban? Can't smoke on the sidewalk or in the park etc.
I'm sure I've missed many but you get the idea. Once any level of government is allowed to institute a ban of one type, others are much easier to implement.
So, where does it stop?
In the case of animals (dog chaining included) enforcement of current animal welfare laws would help solve the problems that the ban would without punishing those who do it correctly.
Stop allowing the government to spend these countless amounts of dollars on bans and insist they put that money into the funding of educational programs and enforcement of the current laws. Upgrade the current laws, and put money into enforcement where it's actually needed.
