Breeding your first litter of puppies is an exciting but complex undertaking that requires careful planning, financial preparation, and a commitment to the health and welfare of both your dog and her offspring. This comprehensive guide walks you through every stage of the breeding process, from initial preparation to caring for newborn puppies.
- Wait until your female is at least 2 years old to complete required health testing
- Budget a minimum of $3,000-$5,000 for a healthy litter; emergency C-sections can cost $2,500+
- Complete all breed-specific health clearances (hips, elbows, eyes, heart, genetic testing) before breeding
- Dog pregnancy lasts approximately 63 days (58-68 days is normal)
- Have your veterinarian’s emergency number ready—know the warning signs that require immediate care
Before You Breed: Essential Questions to Ask Yourself
Responsible dog breeding begins with honest self-assessment. The American Kennel Club emphasizes that your underlying purpose should be to improve the breed—not just increase its numbers.
- Do I have the time to care for a pregnant dog and raise puppies for 8-12 weeks?
- Can I afford unexpected veterinary emergencies (C-sections, sick puppies)?
- Does my dog have an excellent temperament worth passing on?
- Is my dog a good representative of the breed standard?
- Am I prepared to take back any puppy at any point in its life if needed?
- Do I have a mentor or experienced breeder to guide me?
Breeding is rarely profitable. Most responsible breeders break even or lose money on their first litters after accounting for health testing, veterinary care, supplies, and the time invested.
Step 1: Understand Age Requirements
The age at which you breed your dog significantly impacts the health of both mother and puppies. For a detailed breakdown of optimal breeding ages by breed size, see our guide to the best age for breeding dogs.
Female Dogs
While female dogs typically reach sexual maturity between 6-12 months of age, responsible breeders wait until the second or third heat cycle—around 18-24 months. This timing allows:
- Full physical maturity for safer pregnancies
- Completion of required health testing (hip and elbow evaluations require dogs to be 24 months)
- Time to assess adult temperament
AKC Registration Rules: The AKC does not allow registration of litters from a dam less than 8 months or more than 12 years of age at the time of mating, except with special documentation.
Male Dogs
Male dogs may produce sperm by 6 months, but veterinarians recommend waiting until 12-18 months to ensure full maturity and healthy sperm quality. Most experts agree that breeding between ages 2-5 produces the healthiest puppies with fewer complications.
Step 2: Complete Health Testing
Health testing is non-negotiable for responsible breeding. Each breed has specific requirements established by parent clubs in collaboration with the Orthopedic Foundation for Animals (OFA). Our comprehensive health testing guide covers OFA certifications, CHIC requirements, and breed-specific genetic testing in detail.
Common Health Evaluations
| Test Type | What It Evaluates | Age Requirement |
|---|---|---|
| Hip Evaluation (OFA/PennHIP) | Hip dysplasia risk | 24 months for final certification |
| Elbow Evaluation | Elbow dysplasia | 24 months |
| Eye Exam (CERF/OFA) | Hereditary eye diseases | Annual; valid for 12 months only |
| Cardiac Exam | Congenital heart defects | Varies by breed |
| DNA/Genetic Testing | Breed-specific genetic diseases | Any age |
| Brucellosis Test | Bacterial infection causing sterility | Within 30 days of breeding |
CHIC Certification: When dogs pass all breed-specific tests and owners allow results to be publicly listed, they receive Canine Health Information Center (CHIC) certification—a mark of a responsible breeder.
Genetic Testing
DNA tests identify whether a dog carries genetic variants linked to disease. Most genetic conditions are recessive, meaning both parents must carry the mutated gene for puppies to be at risk. Responsible breeders never breed two carriers together.
Step 3: Find the Right Stud Dog
The stud dog contributes 50% of each puppy’s genetic material. Begin searching 3-6 months before your female’s expected heat cycle to allow time for proper evaluation. For detailed guidance on evaluating studs, negotiating fees, and understanding contracts, see our complete guide to finding a stud dog.
- Completed health testing with documented results
- Excellent temperament and breed type
- Compatible pedigree (avoid close inbreeding)
- Proven fertility (especially for first-time breeders)
- Clear written contract with the stud owner
Stud Fee Considerations
Typical stud fees range from $250-$1,000, though champion or health-tested dogs may command $3,000-$10,000 or more. Some stud owners accept pick of the litter instead of cash payment.
Step 4: Prepare for Breeding
One month before mating, schedule a thorough pre-breeding veterinary examination. Your vet should:
- Confirm your female is in good overall health
- Update vaccinations
- Test and treat for parasites
- Test for brucellosis (both dogs)
- Discuss progesterone testing to determine optimal breeding timing (see our heat cycle guide for details)
Optimal Breeding Day: According to the AKC, the optimal breeding day for litter size is two days post-ovulation, as determined by your veterinarian through progesterone testing.
Step 5: Understanding the Pregnancy Timeline
Dog pregnancy (gestation) lasts approximately 63 days, though 58-68 days is considered normal. Here’s what to expect week by week:
Fertilized eggs travel to the uterus. No visible signs of pregnancy. Your dog may seem normal or slightly quieter. Some experience mild nausea.
Embryos implant into the uterine wall around days 16-20. By day 25, a veterinarian can confirm pregnancy via ultrasound. Experienced breeders may detect puppies through gentle abdominal palpation around day 28.
Belly begins swelling noticeably. Weight gain becomes apparent. Nipples darken and enlarge. Puppies grow rapidly—gaining about 75% of their birth weight during this period.
Deworm the mother with veterinarian-approved medication. Set up the whelping box. Your dog may begin shedding fur from her belly—a natural preparation for nursing.
Puppies are fully developed. X-rays can now accurately count puppies (skeletal calcification complete around day 45). Mother begins producing colostrum. “Nesting” behavior increases. You may see and feel puppies moving.
Watch for signs of labor: restlessness, panting, nesting, loss of appetite. Temperature drops below 99°F approximately 24 hours before labor begins. Normal labor lasts 3-12 hours.
Feeding During Pregnancy
Switch to a high-quality growth or performance food around day 45, as these are nutrient-dense and support increased energy needs. At whelping, a healthy mother should weigh 5-10% more than before breeding.
Step 6: Set Up the Whelping Area
Prepare the whelping box at least 2 weeks before the due date so your dog can become comfortable with it.
Whelping Box Requirements
- Size: At least one foot longer than your dog stretched out
- Pig rails: 3-4 inch rails around the inside perimeter to prevent crushing
- Bedding: Washable vet bed or towels (avoid hay, straw, or small blankets)
- Location: Quiet, warm area away from household traffic
Essential Whelping Supplies
Medical Supplies
- Digital thermometer
- Unwaxed dental floss (for cord tying)
- Blunt scissors (sterilized)
- Iodine solution
- Bulb syringe (for clearing airways)
- Sterile gloves
Comfort & Care
- Heating pad or heat lamp
- Clean towels (many)
- Digital scale for weighing puppies
- Notebook for recording births
- Puppy milk replacer (emergency)
- Colored ribbons for ID
Have your vet’s emergency number ready! Many whelping emergencies happen at night. Know the location of your nearest 24-hour emergency veterinary clinic.
Step 7: Recognizing Labor and Delivery
Pre-Labor Signs (12-24 hours before)
- Temperature drops below 99°F (normal is 100-102.5°F)
- Restlessness, pacing, nesting behavior
- Loss of appetite
- Some dogs may vomit
- Seeking seclusion
Active Labor
Active labor typically lasts 3-12 hours. Each puppy should arrive within 30-60 minutes of active pushing, with up to 2 hours between puppies considered normal.
Call Your Vet Immediately If:
- 30-60 minutes of strong contractions without a birth
- More than 4 hours pass between puppies
- Green discharge appears without a puppy following within 20 minutes
- Your dog appears in severe distress or exhausted
- A puppy is stuck in the birth canal
- Labor hasn’t started within 24 hours of temperature drop
Brachycephalic Breeds
English Bulldogs, French Bulldogs, Pugs, and other brachycephalic breeds often cannot deliver naturally because puppy heads are too large for the birth canal. These breeds typically require scheduled Cesarean sections.
Step 8: Caring for Newborn Puppies
Temperature Is Critical
Newborn puppies cannot regulate their own body temperature. Maintain these environmental temperatures:
| Puppy Age | Environment Temperature | Puppy Body Temperature |
|---|---|---|
| Days 1-5 | 85-90°F | 95-99°F |
| Days 7-10 | 80°F | 97-100°F |
| Week 4 | 70-75°F | Normal adult range |
Feeding Schedule
Healthy puppies nurse every 2-3 hours around the clock. Colostrum (the mother’s first milk) provides 95% of puppies’ immunity during the first 24 hours—ensuring all puppies nurse within this window is critical.
Weight Monitoring
Weigh puppies daily for the first 2 weeks, then at least every 3 days. Healthy puppies should:
- Gain approximately 10% of body weight daily
- Double their birth weight within the first 1-2 weeks
- Never lose more than 10% of birth weight in the first 24 hours
Before Supplemental Feeding: Never feed a cold puppy. Always check rectal temperature first—a puppy must be between 96-99°F before feeding. Cold puppies cannot digest milk properly.
Costs to Expect
Breeding dogs responsibly requires significant financial investment. Here’s a realistic breakdown:
| Expense Category | Estimated Cost |
|---|---|
| Health testing (OFA, genetic, brucellosis) | $200-$500 |
| Stud fee | $250-$3,000+ |
| Pre-breeding vet exam and progesterone testing | $150-$400 |
| Pregnancy ultrasound/x-rays | $100-$300 |
| Whelping supplies | $200-$500 |
| Emergency C-section (if needed) | $1,500-$3,000+ |
| Puppy veterinary care (exams, vaccines, deworming) | $150-$300 per puppy |
| Puppy food and supplies | $200-$400 |
| Total (normal delivery) | $1,500-$5,000+ |
Expert Advice: Have at least $4,000 in savings before breeding, with a backup plan if puppies don’t sell or unexpected complications arise.
Common Mistakes First-Time Breeders Make
- Breeding too young: Not waiting for full maturity and health testing
- Skipping health tests: Assuming a healthy-looking dog is genetically clear
- No contract: Breeding without written agreements
- Underestimating costs: Not having emergency funds available
- Going it alone: Not having a mentor or vet relationship established
- Poor timing: Not using progesterone testing for optimal breeding
- Unprepared for whelping: Not having supplies ready weeks in advance
Building Your Support Network
The AKC strongly recommends that first-time breeders build a support network before breeding:
- Join your local breed club to meet experienced breeders who can mentor you
- Establish a relationship with a reproductive veterinarian who can guide you through the process
- Connect with your breed’s parent club for breeder education resources
- Take the AKC Breeder Education courses covering genetics, anatomy, whelping, and nutrition
Frequently Asked Questions
Dog pregnancy lasts approximately 63 days (9 weeks) from ovulation. However, anywhere from 58-68 days is considered normal, which is why tracking ovulation through progesterone testing is important for predicting the due date accurately.
Most veterinarians and responsible breeders recommend waiting until a female dog is at least 2 years old. This allows time for the dog to reach full physical maturity and complete all required health testing, including OFA hip and elbow evaluations which require dogs to be 24 months old.
Required tests vary by breed, but commonly include: OFA hip and elbow evaluations, eye certification (CERF/OFA), cardiac examination, breed-specific DNA genetic testing, and brucellosis testing within 30 days of breeding. Check with your breed’s parent club for specific requirements.
A healthy litter with normal delivery typically costs $1,500-$5,000+ including health testing, stud fees, veterinary care, whelping supplies, and puppy care. Emergency C-sections add $1,500-$3,000+. Experts recommend having at least $4,000 in savings before breeding.
Call your vet immediately if: strong contractions continue for 30-60 minutes without a birth, more than 4 hours pass between puppies, green discharge appears without immediate delivery, your dog shows signs of severe distress or exhaustion, or labor hasn’t started within 24 hours of the temperature drop.
During the first 4-5 days, maintain the whelping area at 85-90°F. Gradually decrease to 80°F by day 7-10, and 70-75°F by week 4. Newborn puppies cannot regulate their own body temperature, and cold puppies cannot properly digest milk.
