Answer: Sanitary retrictions and extre payment for pet transportation are the key. And I seriously believe that an act of dog exploitation fits in my little essay.
Explanation: Imagine that you clean your house from the bottom to the top every single day, and one of your friends,classmates or coworkers wants to take a rest in your living room. We´re going to have a certain number of rules in order to keep your house nice and clean, right?. Well, same thing happens with airlines. We´re going to take a look at some hypothetical examples based on airlines common rules about this. Airline"X" has a restriction that established that you can only take a flight with your pet if the flight lasts less than 6 hours. And of course,your pet has to have a vaccine certification that proves that it´s not carrying any human or non-human desease (and it can´t be under veterinary treatment). Your pet also must be at least 6 months old. Airline X can olny transport your pet inside an appropiate cage. In therms of extra payment, charge can goes from 80 dollars.
Airlines are very estrict in this cases. So imagine them with a case of dog exploitation. No way!.
