It can be difficult to tell whether a dog is pregnant until the last few weeks of her nine-week gestation, when her belly's increase in size is hard to miss. The most surefire way to find out is by taking her to a vet, but being aware of physical and behavioral changes that may take place is also useful. It's a tough call at first without you going to a vet. She may change her normal mood but to tell in the first few weeks is not an easy thing to do.
