Things You'll Need
- Veterinarian
Instructions
Pay attention to your lab's attitude.Does she suddenly seems more aggressive or territorial than usual, or is she avoiding the company of others?
Measure the amount of food your dog eats each day. Pregnant dogs may experience a decrease in appetite, followed by an increase.
Watch your dog for signs of a lack of energy, such as sleeping more and playing less.
Check to see if your black lab's stomach has begun to expand, or if her nipples have grown.
Take your black lab to a vet for an ultrasound. This will not only tell you if she is pregnant, but will give you an estimate of how many puppies you can expect.
