How To Tell If Your Border Collie Is Pregnant

Expecting a new puppy is exciting for both you and your dog.

Whether you are intentionally breeding your dog or not, there are a few signs to tell if your dog is pregnant.

Like humans, dogs have a fertile period too.

This period is known as “being in heat“, taking place every 8 months and can last up to a month.

Pregnancy in dogs typically lasts for about 9 weeks (between 58 to 68 days).


Unfortunately, there are no home tests to find out if your dog is pregnant.

However, there are some signs you can look out for.

Wondering if your Border Collie is pregnant?

Read on to find out some signs to look out for and tips to help!


Signs of Border Collie Pregnancy

As most dogs do not show signs of pregnancy during the first few weeks, it may be hard to determine if they are pregnant at an early stage.

Typically, signs will start showing along their second trimester.


1. Weight Gain and Vomiting

While uncommon, your Border Collie may have nausea and vomiting in their second trimester due to hormonal changes.

During this time, they may gain weight slowly, with their weight gain being noticeable by day 35.

If your Border Collie vomits and loses her appetite during her pregnancy, it is important not to force her to eat.

Most dogs would not skip more than a day or two without eating.

However, if she has not eaten for three days in a row, you should consult your vet.

As her appetite will fluctuate throughout her pregnancy, be prepared to alter her eating accordingly.


2. Decrease in Activity

If your Border Collie is normally energetic, a sudden decrease in energy may be a sign that she is pregnant.

Dogs too feel tired as their hormone level changes when pregnant.

This decrease in activity can begin as early as two weeks into her pregnancy and may change as she adapts to her pregnancy.


3. Breast Development

As she starts her pregnancy journey, your dog may develop breasts.

This means that her milk glands beneath her nipples are developing.

During this time, her nipples may also change colour, becoming more pinky-grey.

This is due to an increase in blood flow around that area.

Changes in pregnant dogs breasts typically start around 25 to 30 days into her pregnancy.


4. Vaginal Discharge

While this is not an early sign of pregnancy, your dog may get a vaginal discharge at one point.

While it is normal, there are certain types of vaginal discharge that are unusual, including:

  • Bloody discharge
  • Mucus with blood
  • Mucus that is not clear or slightly cloudy
  • Mucus with a bad odour


If you notice that your dogs’ vaginal is unusual, consult your vet immediately.
