How do you know when a papilion dog is pregnant?

You can suspect a Papillon dog is pregnant if she exhibits signs such as increased appetite, weight gain, changes in behavior (like nesting), and enlarged nipples around three weeks after mating. A veterinary examination can confirm pregnancy through ultrasound or blood tests. Additionally, physical changes, like a swollen abdomen, typically become noticeable around the fifth week. It's important to consult a veterinarian for proper care and monitoring throughout the pregnancy.
