Yes, they are but comparing pigs to dogs (or children) is like comparing apples to Oranges. Animals develop specializations according to their surroundings. Pigs are smart enough to be able to survive in their environment just as an octopus.
Yes
Yes pigs are amazing, they are intelligent lovable animals.

Because pigs are intelligent animals and prefer to travel by sea.
No. Pigs are pretty clever, but are not the "smartest species in the world". Border collies are probably more intelligent; certainly, they are capable of understanding more words than pigs are. I think that pigs get a reputation for "smartness" because pigs constantly exceed the farmer's low expectations of them. Further, you would need to define some measure of "brightest" in order to determine what the "brightest" species in the world would be. Would dolphins or whales qualify? They don't use tools - but they have nothing to use tools WITH. But based on the sizes of their brains, whales or elephants ought to be fairly intelligent, and in practice they are. More intelligent than humans? Difficult to say; we would need a better definition of "intelligence" than we have now in order to answer this question.
Humans, dolphins or pigs.
There are likely more/better reasons, here's some: - Humans and pigs are both omnivores - Certain organs are similar enough between the species to be able to function in the other species without the body rejecting it - Pigs are deemed to be one of the most intelligent animals (bringing them somewhat closer to humans)
Pigs are not dogs. They are two different species.
The human species is known for its exceptional intelligence.
Giraffs
Some people keep them as pets, others farm them for food. Pigs are intelligent pets and tasty food.
Nope. All species of pigs can't fly.
