Part 1

Swollen belly

A rounder and firmer stomach could be a sign of pregnancy.

Believe it or not, most dogs don’t “show” their pregnancy until the third half of pregnancy, which is 6 to 9 weeks since conception. If your dog’s stomach is more pronounced than usual, she’s most likely pregnant (especially if her nipples and mammary glands are swollen and plump).

Tires easily

A sudden change in a dog’s energy levels could signify pregnancy.

A pregnant dog may be drowsier or more lethargic than normal, especially as her belly grows. This is most noticeable if your dog is naturally full of energy. Take note if your dog would rather take an abnormal nap than play fetch like usual.

More affectionate or irritable

Your dog’s behavior could change subtly or drastically if she’s pregnant.

How a dog emotionally reacts to her pregnancy all depends on her personality. Some dogs become more affectionate and attention-seeking, while others shy away from pets and cuddles. So, notice if your dog suddenly wants to be pet all the time or hides in a room away from people and other animals.

Nesting behavior

Like humans, a dog will start preparing for her baby’s arrival.

Jamie Freyer, DVM Licensed Veterinarian Expert Interview Your dog may gather blankets, shred paper, or bunch together bedding or clothing to make a warm nest for her puppies. This behavior isn’t always observed, but if your dog does this out of the blue, she’s most likely about to whelp (give birth).

Physical examination

A veterinarian will most likely do a palpation test to check for pregnancy.

This physical examination is painless, and only requires the veterinarian to feel the outside of your dog’s belly with their forefingers. This helps them examine the womb and feel the outline of the potential puppies. Jamie Freyer, DVM Licensed Veterinarian Expert Interview

Hormone test

A veterinarian can take your dog’s blood to run a pregnancy hormone test.

Jamie Freyer, DVM Licensed Veterinarian Expert Interview With this test, they’re looking for the hormone relaxin, which is generally present during the 4th week of pregnancy. If relaxin is present, your dog is definitely pregnant.

Ultrasound

If pregnancy is suspected, a veterinarian will perform an ultrasound.

With this, they can listen for heartbeats and count how many puppies there are (just like a human ultrasound). This is a sure way to confirm pregnancy in your dog, as long as she’s 2 or more weeks pregnant.
