They're the worst and ugliest model added to the game since a long time. I can only laugh at people using one as a mount, it's also the reason why I consider Stone Guard the worst boss in this tier. They're considered dogs btw, not cats.
I think that guy was just trying to ruffle your feathers.
Chinese guardian lions, known as Shishi (Chinese: 石獅; pinyin: shíshī; literally "stone lion") or Imperial guardian lion, and often called "Foo Dogs" in the West, are a common representation of the lion in pre-modern China.
so there you have it. the originals are lions, but people from the west think they are dogs for some weird reason, so blizz made them "lion dogs". since the mogu are "lion people", they call their lion dogs as just "hounds".

also: Stone lions feature in a well-known Chinese tongue-twister: sì shì sì, shí shì shí, shí sì shì shí sì, sì shí shì sì shí, sì shí sì zhī shí shī zǐ shì sǐ de. (4 is 4, 10 is 10, 14 is 14, 40 is 40, 44 stone lions are dead.)
