You can tell whether a dog is pregnant by observing a change in the eating habits. The dog may have either an increase or decrease in appetite. Another common sign is enlarged teats. Take the dog to a doctor for tests in order to know for sure.
When It has a baby in 3 or 4 weeks.
The only certain way is to get an ultra sound. But it's better if she isn't so if she isn't or its still really early in the pregnancy GET YOUR DOG SPAYED. -vet
