No of course not. Actually they shouldn't wear muzzles if they aren't dangerous. A proper trained rottweiler can be the most loyal companion in the world. Even more they can be a bot of a pushovers (This counts for pitbulls too.)
no they dont only if they bite
depends what breed it is, there is a law that states that some breeds have to wear muzzles in public.
I think you mean muzzles. I imagine that different countries have different laws with regard to muzzling dogs. In the United Kingdom the law states that only certain breeds, which have been legally defined a 'dangerous,' need to be muzzled in public places.
Not at all.
No. It is against the law.
Yes. On all boats you have to wear lifejackets. If you live in the USA it's the law in till your 15.
In Australia it is a national law that people of all ages have to wear a bicycle helmet while they are on theirs bikes.
Never in CA. It is the law that a helmet is worn at all times.
Age does not matter since the law says all passengers must wear seatbelts.
Must wear at all times while operating a motor vehicle.
All men will grow beards and all women will wear burqas
You're not required by law to wear a helmet but i suggest u do
