OFA patella, cardiac, and tracheal hypoplasia are required for a Bulldog CHIC number. PennHIP for hips. Annual ACVO eye exam. Comprehensive DNA panel.
Both parents should be RFG Grade 0 or 1 on the Cambridge / Royal Kennel Club scheme. Grade 2 is conditional. Grade 3 is breeding-disqualifying.
Progesterone-timed chilled or surgical AI is the responsible default. Natural tie is unreliable and risks heat stress in a brachycephalic stud.
Day-55 radiograph counts puppies. Schedule a daytime C-section for day 60 to 62 with a brachycephalic-experienced surgical team.
Short answer
The OFA Bulldog CHIC requires three tests: patella, cardiac, and tracheal hypoplasia. The responsible floor adds an annual OFA-CAER eye exam, a PennHIP hip evaluation (preferred over OFA hips for the breed), and a DNA panel covering HUU, DM, and Cystinuria. The Bulldog Club of America Code of Ethics is the parent-club baseline for any of this to count.
The Bulldog Club of America [2] publishes the breeder ethics baseline. Its companion health-testing matrix[3] reads against the OFA-CHIC programme. For the Bulldog CHIC number, patella, cardiac, and tracheal hypoplasia are the three required evaluations[5]. Eyes, hips, thyroid, and deafness are listed as optional but recommended, which is how most reputable breeders interpret them: do them anyway.
Tracheal hypoplasia is the test most non-Bulldog breeders have never heard of. OFA defines a normal Bulldog trachea as roughly twice the width of the third proximal ribat the thoracic inlet, measured on a standard radiograph[6]. A narrow trachea sharply raises anaesthetic and heat-stress risk and is heritable, which is why it sits at the top of the CHIC list.
Why PennHIP, not OFA, for Bulldog hips
Subjective grade (Excellent / Good / Fair / Borderline / Mild / Moderate / Severe). Bulldog pass rates are historically very low; the breed conformation distorts the visual grade.
Quantitative measure of hip-joint laxity (0 to 1). More useful for selecting against dysplasia in a low-pass-rate breed. Scored from 16 weeks of age[7].
OFA hip evaluation is only valid at 24 months and older; PennHIP scores are valid from 16 weeks but most breeders wait until 12 months for the breeding decision[4].
Annual ACVO eye exams (registered with OFA-CAER) catch entropion, ectropion, prolapsed nictitating membrane gland ("cherry eye"), and corneal ulcers, all of which run high in the breed[8]. The RVC VetCompass dataset found Bulldogs had 26.79 times the odds of cherry eye and 38.12 times the odds of skin-fold dermatitis compared with non-Bulldogs[13]. Annual ophthalmology and dermatology checks are not optional in practice.
The DNA panel covers the breed-relevant single-gene conditions: Hyperuricosuria (HUU), where affected dogs form urate bladder stones; Degenerative Myelopathy (DM), an adult-onset spinal-cord disease; and Cystinuria, another urate-stone risk[26]. Test both parents and avoid mating two carriers of any of the three.
Short answer
Wait until your female is at least 24 monthsold, on her second or third heat. Your male is sexually mature around 12 months but should not be used for planned breeding until OFA cardiac, patella, and tracheal hypoplasia clearances are in hand and his RFG airway grade has been scored. The 24-month threshold matters because OFA hip and cardiac evaluations are only valid from that age.
Wait for the second or third heat. Earlier mating raises dystocia risk in a breed where almost every litter is already a surgical delivery.
Sexually mature earlier, but OFA cardiac and full RFG airway grading should be complete before any planned pairing.
Why progesterone timing matters more for a Bulldog
Bulldog heats can be quiet, with little visible discharge and subtle behavioural shifts. Calendar timing misses the fertile window, and because the mating will be done by AI, the AI window has to be hit on the right side of the LH surge. Progesterone testing is the only reliable way to land it.
Your vet draws blood starting around day 6 and every 2 to 3 days[16]. Cost runs $50 to $150 per draw, typically 2 to 4 draws per cycle[17]. Every breed ovulates at the same progesterone level: a Bulldog and a Mastiff and a Chihuahua all peak at 5 to 8 ng/mL[19].
One more pre-breeding test
A brucellosis blood test within 30 days of mating, $50 to $100 per dog. Brucellosis causes stillbirths and can spread to humans, so a stud owner who skips it is the kind of partner you decline[2].
Our best age to breed a dog guide covers the same timing rules across breeds.
Short answer
The Bulldog cannot reliably reproduce itself. Body conformation makes natural tie fail in most attempts, and about 80 to 95 percent of Bulldog littersare delivered by C-section. AI replaces the unreliable tie; an elective day-62 surgery replaces the 3 a.m. emergency. The RVC VetCompass programme found Bulldogs have 2.04 times the odds of being diagnosed with any disorder versus other dogs (O'Neill et al., 2022).
Deep chest and short legs prevent a reliable tie. Heat exertion during forced mating risks BOAS collapse in a brachycephalic stud[18].
Round puppy head, broad shoulders, narrow dam pelvis. Roughly 80 to 95 percent of litters cannot deliver vaginally[14].
The three AI methods, and what they cost
Chilled semen shipped overnight, deposited transcervically by a reproductive vet. Conception rate around 60 to 75 percent when progesterone-timed.
Endoscope-guided deposit directly into the uterus. Higher conception rate, less anaesthetic burden than surgical AI. Preferred middle option for Bulldogs.
Laparotomy with direct uterine deposit. Used for frozen semen and difficult-cycle dams. AKC currently restricts registration of one-time-use surgical AI; most labs now offer TCI as the alternative[18].
Chilled-semen import adds $250 to $500 in shipping plus semen storage fees. Frozen storage runs $100 to $300 per year per straw.
The Cambridge BOAS Research Group and the Royal Kennel Club jointly operate the Respiratory Function Grading (RFG) scheme, a standardised assessment of upper airway function in brachycephalic breeds[9]. A trained vet listens to the dog at rest with a stethoscope, then again immediately after a three-minute trot, and assigns a grade from 0 to 3[10]. The Kennel Club's public-facing summary names Bulldogs explicitly as one of the brachycephalic breeds the scheme is built for[11]. The AVMA documented the rollout in the US veterinary press[12].
RKC / Cambridge Respiratory Function Grading
Clinically unaffected. Best breeding candidate.
Mild signs. Breed only to Grade 0.
Moderate. Cambridge advises against breeding.
Severe. Disqualifying. Refer for airway surgery.
US owners can request the assessment from a reproductive specialist or a university veterinary teaching hospital using the published Cambridge protocol; the formal RKC certificate is currently UK-only[11].
Neonatal mortality after a C-section is meaningfully higher in brachycephalic litters than non-brachycephalic ones (Adams et al., 2022). The gap narrows when the surgery is planned and the team is set up for brachycephalic neonates[15]. A scheduled day-62 surgery lets the practice pre-warm the theatre, dedicate a nurse to each puppy for resuscitation, and avoid the staffing gaps of an overnight emergency.
5 questions to ask the stud owner about AI and whelping history
The brachycephalic conformation is the trade-off baked into the breed standard. Responsible Bulldog breeding means respecting it: pair RFG Grade 0 parents, keep them lean and cool, plan AI around progesterone, and book the C-section in advance.
Short answer
The Royal Veterinary College VetCompass programme analysed 2,662 UK English Bulldogs against a comparator population of 22,039 non-Bulldogs. Bulldogs had 2.04 times the odds of being diagnosed with at least one disorder; median lifespan was 7.2 years. The four single largest predispositions were skin-fold dermatitis (38.12x), prolapsed nictitating membrane gland (26.79x), mandibular prognathism (24.32x), and BOAS (19.20x) (O'Neill et al., 2022).

The VetCompass authors concluded that the Bulldog's disorder burden is driven by extreme body shape and called for "immediate redefinition of the breed towards a moderate conformation"[13]. For a first-time breeder, the practical reading is narrower: the three biggest levers an individual programme can pull are (a) breed only RFG Grade 0 or 1 parents, (b) keep adults lean (BCS 4 to 5 of 9), and (c) climate-control the home.
Heat stress is the acute mortality risk to plan for
Bulldogs cool by panting, and a brachycephalic skull cuts that capacity sharply. Ambient temperature above 75 degrees Fahrenheit, humid still air, or any sustained exertion can tip a Bulldog into heat stroke within minutes.
For the daily-care side of the breed (wrinkle hygiene, dental care, tail-pocket cleaning), Cornell's BOAS overview is a clean reference for buyers[21]. Add it to the puppy-pack you send home with the litter.
Short answer
Pick a mate with the OFA Bulldog CHIC trio (patella, cardiac, tracheal hypoplasia) plus ACVO eyes, PennHIP hips, and a DNA panel; an RFG Grade 0 or 1; a five-generation inbreeding score below 6.25%; and a stable temperament. Walk away from any pairing where one parent is RFG Grade 2 or worse, where the owner avoids sharing OFA numbers, or where the stud has never been bred by AI before.
Coefficient of inbreeding thresholds
Target zone. The Bulldog gene pool is small; aim lower than the toy-breed default.
Caution. Recessive-disease risk climbs sharply on a breed already this homozygous.
Disqualifier in most BCA-aligned programmes.
Coefficient of inbreeding (COI) shows how closely the parents share ancestors[27]. Our dog breeding compatibility calculator gives a quick estimate; a kennel-club pedigree report is the official one.
The rest of your pre-pairing checklist
If both breeders are in the AKC Bred with H.E.A.R.T. programme, they have agreed to follow a health-testing plan and ongoing breeder education[24]. Pair that with our step-by-step ethical breeding guide for the full pre-mating workup.
Short answer
Expect $4,500 to $9,000 up front before the first mating: health workup, AI, and the elective C-section as a budgeted line item, not an emergency contingency. Then plan another $1,500 to $3,500 for prenatal care, whelping supplies, neonatal hand-feeding, and the first round of puppy shots and deworming. Combined with an average litter of 3 to 4 puppies, the per-puppy math is the tightest of any AKC breed.
Estimated cost of a first Bulldog litter
Ranges are typical US pricing. The AI and elective C-section rows are baseline line items, not contingencies, because roughly 80 to 95 percent of Bulldog litters require surgical delivery[14].
What can the puppies sell for?
Market range only, not a Petmeetly endorsement. Average Bulldog litter is 3 to 4 puppies[23], which is half what a sporting breed delivers and means one neonatal loss can wipe out the litter's margin.
The Bulldog cost-to-revenue ratio looks healthy on paper and tight in practice. One emergency uplift (the dam needs the C-section at 2 a.m. on a holiday weekend), one hand-feeding-intensive puppy, or one neonatal loss flattens the spread. Our dog breeding checklist covers the rest of the pre-mating workup.
A Bulldog pregnancy lasts about 63 days from ovulation. Day 28 ultrasound confirms the pregnancy and gives an early count. Day 55 X-ray confirms the final count and checks fetal skeletal maturity. That radiograph is what fixes the C-section date, typically day 60 to 62.
The day-by-day plan most Bulldog breeders follow
Progesterone-timed insemination at ~10 ng/mL.
Confirm pregnancy. Detect heartbeats. Approximate count.
Final puppy count from skull and spine ossification.
Scheduled daytime surgery, brachycephalic-experienced team.
Call the surgical team early if any of these happen
Labour is starting. Move to surgery before any contraction phase begins.
Green (uteroverdin) signals placental separation. A puppy is in distress[20].
BOAS-driven respiratory compromise on top of labour stress. Emergency, not "wait and see"[22].
The pup is too large for the pelvis. Surgery, not medical management.
Why the planned surgery beats the emergency.A scheduled daytime C-section lets the practice pre-warm the theatre, dedicate one nurse per puppy for resuscitation, and avoid the staffing gaps of an out-of-hours emergency. Neonatal mortality after a planned C-section is lower than after an emergency C-section in brachycephalic litters (Adams et al., 2022)[15].
Weigh every Bulldog puppy three times a day in the first week. Average birth weight is 8 to 12 ounces (227 to 340 g). Healthy puppies gain 5 to 10 percent of birth weight per day in the first two weeks. Any puppy not gaining for 12 hours needs immediate supplementation with a commercial puppy milk replacer; expect at least one hand-feeder per Bulldog litter in practice. Cow milk causes diarrhoea and is not a substitute.
Our dog breeding compatibility calculator projects whelping dates from a known mating day. Also see our broader step-by-step ethical breeding guide for the full pre-whelping checklist.
Clauses every Bulldog stud contract should name
Put the stud deal in writing before the AI date is booked. The American Breeder template covers the parts above[25]. Both owners sign and keep a copy. Verbal agreements are the main reason stud deals end in arguments, and a Bulldog deal involves enough moving parts (semen shipping, AI method, vet bills, C-section booking) to multiply the failure modes.
Rarely, and most responsible Bulldog programs do not try. The breed standard pairs a heavy chest and short legs with a narrow rear. Most stud dogs cannot achieve a tie without handler assistance, and even then the success rate is low and exertion risks heat stress in a brachycephalic dog. Chilled or surgical artificial insemination is the planned route in almost every modern Bulldog mating.
Bulldog puppies have large round skulls and broad shoulders, and the dam has a comparatively narrow pelvis. Around 80 to 95 percent of Bulldog litters are delivered surgically. The Royal Veterinary College VetCompass programme found English Bulldogs have 2.04 times the odds of being diagnosed with at least one disorder compared with other dogs, with body shape driving the difference (O’Neill et al., 2022). Planning an elective C-section around day 62 is safer than letting the dam reach a stalled emergency labour.
RFG is a Bulldog airway grading scheme jointly run by the Royal Kennel Club and the University of Cambridge BOAS Research Group. A trained veterinarian assesses your dog with a stethoscope before and after a three-minute exercise test, then assigns Grade 0 (clinically unaffected), 1 (mild), 2 (moderate), or 3 (severe). Cambridge recommends not breeding from Grade 2 or 3 dogs. In the US the formal scheme is not yet available, but most veterinary teaching hospitals and reproductive specialists can perform an equivalent functional assessment using the Cambridge protocol.
About 63 days from ovulation, with a normal range of 58 to 68 days. A reproductive vet confirms pregnancy by ultrasound around day 28 and counts puppies by X-ray around day 55. Most Bulldog breeders schedule the elective C-section between day 60 and 62, once the count and fetal skeletal maturity are confirmed.
Wait until the female is at least 24 months old. OFA hip and cardiac evaluations are only valid from 24 months, and the BCA Code of Ethics encourages dams to be physically and emotionally mature before a first litter. Bulldog males are sexually mature around 12 months, but the same clearance window applies. Earlier mating raises the risk of dystocia, smaller litters, and poor maternal care.
A Bulldog litter averages 3 to 4 puppies, with a typical range of 1 to 6. First litters are usually smallest (1 to 3 puppies). The small litter size combined with a near-mandatory C-section means the per-puppy cost is among the highest of any AKC breed.
The Bulldog Club of America (BCA) is the AKC-recognised parent club for the breed and publishes the breeder ethics and health-testing baseline. It encourages OFA-CHIC testing (patella, cardiac, tracheal hypoplasia required; eyes, hips, thyroid recommended), refusal to register dogs from non-CHIC pairings, and lifetime take-back contracts for buyers. Following BCA Ethics is the difference between a breeder buyers can trust and a pet-shop pipeline.
The RVC VetCompass 2022 study put median Bulldog lifespan at 7.2 years, compared with around 11 to 12 years for dogs overall. Heat stress, BOAS-related complications, cancer, and heart disease are the most common causes of death. Lean body condition, climate control, and breeding from RFG Grade 0 to 1 parents are the three biggest levers individual owners can pull.
Severely. The brachycephalic skull restricts panting, the primary cooling system in dogs. Ambient temperatures above 75 degrees Fahrenheit can be dangerous, and heat stroke can become fatal within minutes. Exercise has to be moved to cool morning and evening windows; swimming is unsafe because Bulldogs cannot keep their heads above water reliably. Air conditioning is essential for the breeding home.
US pet-quality Bulldogs from a BCA-aligned breeder typically sell for $2,500 to $5,000. Champion bloodlines and rare or pied coats push higher. Puppies sold for under $1,500 are almost always from non-CHIC parents and represent a higher long-term veterinary cost for the buyer.
