We have 2:
Fiance's Corgi. She's 12 1/2, red and white, very high herding drive. Is maybe a little spoiled (maybe a lot spoiled). Technically she's geriatric for a Corgi but you wouldn't know it from looking at her. She's very lovable and affectionate but I don't think I'd call her "sweet." She's definitely got the herding-dog-knows-best mentality.
My cat. Age undetermined; she was an adult when I got her, so she's got to be at least ten years old, but could well be older. She doesn't do much so I can't say she's slowed down. Can't really slow down from "stop." ;) She's shorthaired, solid white, on the small side (only 9 pounds) and has 3 1/2 legs and allergies. She doesn't really harrass you for attention, but she is a cuddler. She likes to snuggle up beside you, unless it's cold, then she wants your lap. She's easily trusted around breakables, crafts, and unattended food, but she claws the crap out of the door trim.
Cat and Corgi do not get along. At all. Thankfully they don't often physically get into it, but we have to break up noisy squabbles every evening when we get home and both pets want attention.
