<human>: How do I know if my pet is pregnant?
<bot>: You can tell if your pet is pregnant by observing changes in behavior, such as increased appetite and activity levels. Additionally, you may notice physical signs such as weight gain or swelling around the abdomen, a change in coat color, or discharge from the vagina or vulva. If your pet is showing any of these symptoms, it's important to take them to a vet for confirmation.
