chihuahuas are the same case. but it also kinda depends on their obesity lol. my chihuahuas are pretty chill, though they're kinda chunky. love 'em lots
if youre nice enough, the chihuahua is your amigo for life. kinda like a little guard doggie. but also ive seen cases where chihuahuas are coocoo crazy even to their owners >_>
yeah, and funny thing is, my chihuahuas act like bulls and cows lol. they ram themselves into someone's legs and they like head wrestling. they also have very T H I C C necks
