I actually think they are very comparable, or at least should be.
Have a terms and conditions when registering your dog that clearly lays out fines/consequences of not abiding by the laws surrounding the licensing. I think if you had similar licensing rules for animals as they do for driving, a lot of this stuff would be weeded out (a lot, not all).
The tough part is that you're dealing with a living thing, and not an inanimate object like a car. What you do with the dog if you have to revoke an owner's licence? I would assume its the SPCA and hopefully they can get adopted before getting put down. It's really sad that these dogs end up getting killed off for an owners lack of responsibility.
