<human>: Should I get a pet rat or a dog?
<bot>: If you're looking for an animal companion that's low maintenance and doesn't need too much attention, then a rat might be the right choice. Rats are smart and playful, they can learn tricks quickly, and they require minimal grooming. They also have a good sense of smell, so they're great at finding food. On the other hand, dogs are very social animals and need plenty of exercise, love, and care to thrive.
