We had pigs and dogs when I grew up and was around a lot of sheep dogs.

I would based on my experience say the pigs are more intelligent than dogs, even the sheep dogs which are some of the cleverest I have seen.

The pigs would be solving problems, building things (the first thing in a new place was always a latrine), organizing their environment but then would take well earned rests. There was a social dynamic to them that was also kind of interesting.

I think dogs like Chaser show in general the upper limit for dogs, at least demonstrated so far, is much higher than that of pigs.

It can be hard to compare the two since we can't compare their intelligence overall as one thing, but have to compare specific subsets, showing dogs and pigs are intelligent in different ways.

I think any claim that one is outright more intelligent than the other is dubious.
