Personally, I found dogs and horses both to be great pets.
Hollywierd aside, I don't think much of pigs as pets.
I recall, thinking back on the original subject of snakes, there was a guy on Georgia Public TV... Okeefenokee Joe... he opined that snakes make interesting pets, but they don't make good pets. I recall one of my cousins-in-law had a couple of big pythons... his father-in-law said if they got loose in his house, he was getting after 'em with his old rabbit-ears shotgun.
