Bring back pet Licences and stop the private sale of pets for profit.

I remember dog licences as a child and we were a poor family, but we had two dogs, plus many other animals; we had all the necessary paper work. It would not cost much, just a database of responsible pet owners, registering their pets. All is needed are rules to be made about selling live animals online or anywhere. People are breeding and selling 'pets' to sell for great sums of money per litter, pretty much unchecked and as undeclared earnings. Regulation would discourage breeding for money.
