Sometimes Kids come to "strange" ideas about what to do with a pet. Therefore it always should be obligatory for the partents or other adults to have a close eye on what is going on there…. Marbles in dog ears are also no fun to have...
In Germany there is a huge political discussion against so called "dangerous breeds" because a few accidents with such breeds have been pushed through the press and tv. There are hard laws on who is allowed to keep these dogs and who is not. There are partially very high taxes you have to pay in several areas when you have a pit or amstaff or kangal or whatever they think is a "dangerous breed".
But there are countries which play it even harder: for example a while ago you where not able to travel from Germany to Holland with a Staff-Mix. They would have taken the dog from you and maybe put it down without you being able to do something against it. But as far as I know, this law has been cancelled....hopefully...
