Breeding dogs is a significant responsibility that requires careful planning, knowledge, and commitment. This comprehensive guide covers everything you need to know about ethical breeding practices in Ireland, from initial health testing to finding loving homes for puppies.
Before You Begin
Dog breeding should never be undertaken lightly or for profit alone. Consider the time, expense, and emotional investment required. Each year, thousands of dogs end up in shelters - ensure you're breeding for the right reasons and can commit to the welfare of both parents and puppies.
Should You Breed Your Dog?
Before deciding to breed, honestly evaluate your motivations and capabilities:
Essential Questions to Ask Yourself:
- Why do you want to breed? Valid reasons include improving the breed, preserving bloodlines, or working abilities
- Do you have homes lined up? Responsible breeders have waiting lists before breeding
- Can you afford it? Emergency C-sections can cost €2,000-€3,000
- Do you have the time? Puppies require 24/7 care for their first 8 weeks
- What if something goes wrong? Are you prepared for stillbirths, sick puppies, or maternal complications?
- Can you take puppies back? Ethical breeders guarantee to take back any dog they've bred
Health Testing and Screening
Responsible breeding starts with comprehensive health testing of both parents:
Essential Health Tests
- Hip and Elbow Scoring: Essential for larger breeds prone to dysplasia
- Eye Testing: Annual examinations by veterinary ophthalmologists
- Heart Testing: Particularly important for breeds prone to cardiac issues
- Breed-Specific Tests: DNA tests for conditions common in your breed
- General Health Check: Complete veterinary examination including blood work
- Brucellosis Testing: Prevents transmission of this serious reproductive disease
Understanding Breed Standards
If breeding pedigree dogs:
- Study your breed's standard thoroughly
- Attend dog shows to understand correct conformation
- Seek mentorship from experienced breeders
- Consider showing your dog to get objective evaluation
- Understand both strengths and weaknesses in your breeding stock
Legal Requirements in Ireland
Dog Breeding Establishment Guidelines
Under the Dog Breeding Establishments Act 2010, you may need to register as a breeding establishment if you:
- Keep 6 or more breeding bitches over 6 months old
- Supply 5 or more litters in a year
- Supply more than 5 dogs in a year

Other Legal Considerations
- Microchipping: All puppies must be microchipped before 12 weeks of age
- Minimum Age: Puppies cannot be sold or rehomed before 8 weeks old
- Record Keeping: Maintain detailed records of all breeding activities
- Tax Obligations: Breeding income must be declared to Revenue
- Insurance: Consider public liability insurance for your breeding activities

Understanding the Heat Cycle
Female dogs typically have their first heat between 6-24 months, depending on breed size:
Heat Cycle Stages:
- Proestrus (7-10 days): Swelling of vulva, bloody discharge, attracts males but won't mate
- Estrus (5-10 days): Fertile period, discharge lightens, willing to mate
- Diestrus (60-90 days): No longer receptive, pregnancy occurs if mated
- Anestrus (4-5 months): Resting phase between cycles
Optimal Breeding Time
- Wait until at least the second or third heat cycle
- Ensure the bitch is fully mature (usually 2+ years)
- Most fertile days are typically days 10-14 of the heat cycle
- Multiple matings 48 hours apart increase conception chances
Progesterone Testing - The Gold Standard
What is Progesterone Testing?
Progesterone testing is a blood test that measures progesterone hormone levels in your bitch's blood. This is the most accurate way to determine the optimal breeding time, significantly increasing the chances of successful conception.
How the Test Works:
- Blood Sample: Your vet draws a small blood sample from your dog
- Laboratory Analysis: The sample is tested for progesterone levels (measured in ng/ml or nmol/L)
- Results Interpretation: Your vet interprets the levels to determine breeding readiness
- Timing: Testing typically starts around day 7-8 of the heat cycle
Understanding the Results:
- Below 2.5 ng/ml: Too early - bitch not ready for breeding
- 2.5-5.0 ng/ml: Pre-ovulation - breeding can begin
- 5.0-10 ng/ml: Ovulation occurring - optimal breeding time
- Above 10 ng/ml: Post-ovulation - breeding window closing
Why It's Essential for Breeding Success:
- Pinpoints Ovulation: Identifies the exact 48-72 hour fertile window
- Maximizes Conception: Increases success rates from 60% to 85%+
- Reduces Waste: Avoids unsuccessful matings and wasted stud fees
- Helps with Timing: Especially crucial for artificial insemination
- Accounts for Individual Variation: Every bitch ovulates at different times
Progesterone Testing Schedule
Typical testing timeline:
- Day 7-8: First test to establish baseline
- Every 2-3 days: Follow-up tests until ovulation detected
- Usually requires 2-4 tests total depending on your dog's cycle
Cost: Expect to pay €30-€50 per test. While this seems expensive, it's far more cost-effective than failed breeding attempts or multiple stud fees.
Pregnancy and Prenatal Care
Canine pregnancy lasts approximately 63 days. Proper care during this time is crucial:
Confirming Pregnancy
- Ultrasound: Can confirm pregnancy from day 25-30
- Palpation: Experienced vets can feel puppies at 28-35 days
- X-ray: After day 45, shows puppy count and positions
- Blood tests: Relaxin hormone test available from day 30
Pregnancy Care
- Nutrition: Gradually increase food intake in final third of pregnancy
- Exercise: Maintain regular gentle exercise, avoid strenuous activities
- Veterinary Care: Regular check-ups, especially in final weeks
- Supplements: Only as recommended by your vet
- Environment: Prepare quiet, comfortable whelping area
- Temperature Monitoring: Track temperature daily in final week

When NOT to Breed
Do Not Breed If:
- Your dog has hereditary health issues
- You cannot afford potential emergencies
- You don't have homes lined up
- Your only motivation is money
- You lack time for 24/7 puppy care
- Your dog has temperament issues
- You're not prepared for the worst-case scenarios
- You cannot commit to lifetime support
Final Thoughts
Responsible dog breeding is a labour of love that requires dedication, knowledge, and significant resources. The goal should always be to improve the breed and produce healthy, well-adjusted puppies that will bring joy to their families for years to come.
Remember that every puppy you bring into the world is your responsibility. By following ethical breeding practices, you contribute to the betterment of dogs in Ireland and help combat the problems caused by puppy mills and irresponsible breeding.
If you're not prepared for the full commitment of breeding, consider other ways to contribute to the dog community, such as fostering, volunteering with rescue organisations, or simply being an excellent owner to your current dog.
