Yes but its easier on the dog if he wasn`t bred
If you are asking whether it is good to neuter a dog, then the answer is yes, if you do not intend to breed with the dog then it is definitely better to neuter the dog. This makes him healthier and happier.
There is not a specific dog breed that is smarter than any other dog breed in the world than there is in the USA, but the smartest dog breed are poodles.
