Pet Pregnancy Calculator
If your pet is expecting, you're probably wondering when the little ones will arrive. Our pet pregnancy calculator helps you estimate the due date for dogs, cats, rabbits, ferrets, and guinea pigs based on their breeding date and average gestation period.
How to Use the Pet Pregnancy Calculator
Using our calculator is simple:
- Select your pet type from the dropdown menu
- Enter the date of breeding (when mating occurred)
- Click "Calculate Due Date"
The calculator will provide an estimated due date along with information about your pet's current pregnancy stage.
Understanding Pet Pregnancy Timelines
Different pets have varying gestation periods:
Dog Pregnancy (Approximately 63 days)
Canine pregnancies typically last about 9 weeks. Signs include:
- Increased appetite in weeks 4-5
- Visible belly enlargement by week 5
- Nesting behavior in the final week
Cat Pregnancy (Approximately 65 days)
Feline gestation is slightly longer than dogs. Watch for:
- Nipple darkening ("pinking up") around week 3
- Weight gain and rounded abdomen by week 4
- Decreased activity near delivery
Small Animal Pregnancy Durations
- Rabbits: 31 days average
- Ferrets: 42 days average
- Guinea Pigs: 68 days average
Important Notes About Pet Pregnancy
While our calculator provides a good estimate, remember:
- Gestation periods can vary by 1-3 days depending on breed and individual factors
- Always confirm pregnancy with a veterinarian
- Nutritional needs increase significantly during pregnancy
- Prepare a quiet, comfortable whelping/queening box 1-2 weeks before the due date
When to Consult Your Veterinarian
Contact your vet immediately if you notice:
- Pregnancy lasting more than 3 days past the due date
- Signs of distress or labor lasting more than 2 hours without delivery
- Bloody discharge before delivery date
- Loss of appetite or lethargy in the pregnant pet
Preparing for Your Pet's Delivery
As the due date approaches:
- Set up a warm, private nesting area
- Have clean towels and emergency vet numbers ready
- Monitor your pet's temperature (a drop often precedes labor)
- Prepare puppy/kitten formula in case supplemental feeding is needed

What if I don't know the exact breeding date?
Use your best estimate. For more accuracy, your vet can perform ultrasound or hormone tests to estimate conception date.
When can you tell if a pet is pregnant?
Vets can often detect pregnancy through palpation at 3-4 weeks, ultrasound at 4 weeks, or X-rays in later stages.
