Yes, it does. My mom actually makes a point to comment on it every time we visit, 'cuz she thinks it'll shame my aunt into taking better care of her pets or cleaning more often. Hasn't worked, though.
My aunt's nuts...she only pays attention to her cats, anyway, her dogs just run around the yard getting all dirty and disgusting (and then she brings them into the house whenever it starts to rain, making the house dirty and disgusting).
I also know a co-worker who has four dogs, but her house is really clean. She pampers them way too much, though. That's the opposite extreme from my aunt. She's the type of person I talked about in the OP (except she's married with kids). She celebrates the dogs' birthdays, she dresses them up for Halloween, she takes them with her on vacation, etc.
We have one small dog (shetland sheepdog) at our house. It's clean, we walk it every day, it sleeps in the garage, it's housetrained, and it doesn't climb on furniture. That's the only way to live with a pet, IMO. Animals are animals, people are people.
