APC requires OFA patellas, cardiac, and OFA-CAER eyes for CHIC. Add thyroid, Legg-Calvé-Perthes, and a PRA-prcd DNA test as the responsible floor.
Patent Ductus Arteriosus (PDA) hits Pomeranians hardest. Confirm the stud and recent ancestors have cardiologist-issued clearances and no Alopecia X in the line.
Coefficient of inbreeding below 6.25 percent, a stable temperament, complementary pedigree, in-standard 3 to 7 lb weight, and at most one merle parent.
Third heat cycle plus 18 months minimum for the dam. Progesterone-timed mating, day-55 radiograph, monitored natural whelping (only 2 percent of Poms need a section).
Short answer
The American Pomeranian Club requires three tests for CHIC certification: OFA patella evaluation, a cardiac evaluation (congenital or advanced), and the OFA-CAER eye examination. Add thyroid, Legg-Calvé-Perthes, and a PRA-prcd DNA test as the responsible floor.
Three tests are the APC floor: OFA patellas, a cardiac evaluation, and an annual OFA-CAER eye exam[4]. The APC singles out luxating patellas, cardiac disease, and hypothyroidism as the breed's three most documented health concerns[3]. AKC publishes a similar breed-specific recommendation set[5].
The thyroid panel and Legg-Calvé-Perthes (LCP) screen are recommended-but-not-required by the APC. Both are high-yield in toy breeds: hypothyroidism affects fertility, and LCP is a hip-joint blood-supply failure that hits small breeds disproportionately. The DNA panel handles the breed-specific PRA-prcd mutation (progressive rod-cone retinal degeneration) and is the cheapest piece of insurance against producing a middle-aged blind puppy.
How to read an OFA patella grade
Patella exams can be done from 12 months. OFA accepts them at any age for the registry[6].
How to read an OFA cardiac clearance
Cardiologist-issued Normal is the gold standard for PDA screening in Pomeranians[4].
Short answer
Wait until your female is at least 18 months old and on her third heat cycle. Your male is sexually mature around 6 to 9 months but should not be used for planned breeding until his OFA patella and cardiac clearances are in hand. Pomeranians come into first heat as early as 4 to 8 months; that is biological readiness, not breeding readiness.
Wait for the third heat cycle. Earlier mating raises the risk of dystocia, hypoglycaemia in the dam, smaller litters, and poor maternal care.
Sexually mature earlier, but patella + cardiac clearances should be in writing before any planned breeding.
Pomeranian females typically have two heat cycles a year, each lasting 2 to 4 weeks. The cycle moves through three phases: proestrus, estrus, and a long rest called diestrus[21].
Breeding her before the third heat raises the risk of hard births, poor maternal care, and added physical stress on a 4-to-7-pound body still growing.
Signs your female is in heat
Why progesterone timing matters more for toy breeds
Pomeranian heats can be quiet, with light bleeding and subtle behavioural cues. Calendar timing (day 10 to 14) misses the fertile window in those cycles, and a missed cycle means a six-month wait. Progesterone testing fixes this.
Your vet draws blood starting around day 6 and every 2 to 3 days[22]. Cost runs $50 to $150 per draw, 2 or 3 draws per cycle being typical[23]. Every breed ovulates at the same progesterone level: Pomeranian, Chihuahua, and Mastiff alike[24].
A male can mate as early as six to nine months, but patella and cardiac clearances should be in writing before any planned breeding[6].
So even a male who looks ready at one year still has paperwork to gather. Our best age to breed a dog guide covers the same timing rules across breeds.
One more test for both dogs
A brucellosis blood test within 30 days of mating, $50 to $100 per dog. Brucellosis causes stillbirths and can spread to humans, so skipping it is a real risk[4].
Short answer
Three Pomeranian-specific risks dominate the breeding decision: Patent Ductus Arteriosus (PDA), the most common congenital heart defect in dogs (Poms are in the highest-risk breed category); tracheal collapse, a toy-breed reality that hits Pomeranians disproportionately; and Alopecia X / Black Skin Disease (BSD), which has a strong familial pattern but no validated DNA test yet. Cardiac is testable today; tracheal collapse and Alopecia X require pedigree audit instead.
Patent Ductus Arteriosus. Most common congenital heart defect in dogs. Pomeranians are in the highest-risk breed category[10].
Cartilage-ring weakness causing chronic cough. Pomeranians account for 6 to 17 percent of toy-breed cases in published referrals[13].
Symmetrical hair loss with darkened (black) skin. Strong familial pattern. No validated DNA test in 2026[14].
PDA is the most common congenital cardiac defect in dogs[9]. Pomeranians sit in the highest-risk breed cluster alongside Chihuahuas, Kerry Blue Terriers, and Shetland Sheepdogs[10]. PDA is roughly three times more common in females than in males[8].
The genetic load matters more than most owners realise. Where both parents have a PDA history, incidence in their puppies can reach 80 percent[8]. Affected dogs should not be bred, even after successful surgical correction. Close relatives of affected dogs should be cardiac-screened before being used in a breeding program.
The screening pipeline is simple. A board-certified veterinary cardiologist listens for the continuous "machinery" murmur characteristic of PDA, and suspected cases are confirmed by echocardiogram[9]. OFA records the result and a cardiologist-issued Normal is the gold-standard clearance the APC CHIC programme accepts[4].
Tracheal collapse happens when the cartilage rings supporting the trachea soften and flatten, producing the classic "goose-honk" cough[11]. The 2024 PMC retrospective on 110 small-breed cases ranks Maltese, Pomeranian, Poodle, and Chihuahua as the top four affected breeds[13]. Pomeranians appear in 6 to 17 percent of US referral caseloads and around 12 percent of an Australian cohort[12].
There is no DNA test, but some Pomeranian lines have measurably weaker tracheal cartilage than others. The breeder lever is pedigree audit: ask the stud owner about chronic cough or surgical intervention in his parents and grandparents, and avoid lines with multiple early-onset cases.
Alopecia X (also called Black Skin Disease, BSD) is a symmetrical, non-itchy hair loss that progresses from the trunk outward, leaving darkened skin behind[14]. It does not affect lifespan, but it is one of the most-searched Pomeranian health terms because of its cosmetic impact.
Research suggests a chromosome-15 association, and the American Pomeranian Club currently funds work at the AKC Canine Health Foundation toward a validated DNA marker. As of 2026, no commercial DNA test exists[14]. The breeder approach today is the same as for tracheal collapse: research pedigrees, avoid lines with documented Alopecia X, and breed only from Pomeranians past the typical onset age of two years.
5 questions to ask the stud owner about cardiac and pedigree history
Of the three pillars, only PDA has a clean clinical test today. Tracheal collapse and Alopecia X are pedigree problems. Responsible Pomeranian breeding means treating "no validated DNA test" as a reason to look harder at the family tree, not a reason to shrug.
Short answer
Pick a mate with the APC-required trio (patellas, cardiac, eyes), a confirmed cardiologist-issued cardiac Normal, no Alopecia X in the line, an in-standard 3 to 7 lb adult weight, and at most one merle parent in the pair. Skip any pairing above 10 percent inbreeding or where the owner avoids sharing health records.
Coefficient of inbreeding thresholds
Target zone. Toy breeds often run higher; aim lower.
Caution. Recessive-disease risk climbs sharply.
Disqualifier in most responsible Pomeranian programs.
Coefficient of inbreeding (COI) shows how related the parents are[20]. Our dog breeding compatibility calculator gives a quick estimate; a kennel-club pedigree report is the official one.
The Pomeranian-specific checklist
If both dogs are in the AKC Bred with H.E.A.R.T. programme, the breeders have agreed to follow a health-testing plan and keep learning[19]. Pair that with our step-by-step ethical breeding guide for the full pre-mating workup.
5 questions to ask the other owner
Short answer
Expect $1,500 to $4,000 up front before the first mating. C-section is an emergency contingency rather than a planned line item (roughly 98 percent of Pomeranians deliver naturally), but budget the uplift anyway. The tiny average litter (1 to 3 puppies) gives Pomeranian breeding the tightest cost-to-revenue ratio of any toy breed in this v7 lineup.
Estimated cost of a first Pomeranian litter
Ranges are typical US pricing. Around 98 percent of Pomeranians deliver naturally, so emergency C-section is the contingency rather than the default line item used for brachycephalic breeds.
What can the puppies sell for?
Market range only, not a Petmeetly endorsement. Average Pomeranian litter is 1 to 3 puppies[17], which means a single emergency C-section can erase the litter's entire margin.
With litters as small as 1 to 3 puppies, the Pomeranian cost-to-revenue ratio is the tightest of any breed in the v7 lineup. A first-time breeder who under-budgets the cardiac evaluation or an unplanned emergency C-section almost always loses money. Our dog breeding checklist covers the pre-mating workup.
Pomeranian pregnancy lasts about 63 days from ovulation. Day 28 ultrasound confirms pregnancy; day 55 X-ray counts puppies. Unlike the brachycephalic breeds, a Pomeranian whelping is usually a monitored natural delivery (about 98 percent of cases). Emergency C-section is the contingency, not the default.
The three stages of a Pomeranian whelping
Restless, panting, nesting, refusing food. Temperature drops below 100°F (37.8°C) 12 to 24 hours before puppies arrive[27].
Visible straining and contractions. First puppy within 4 hours, then 30 to 60 minutes between each[25].
One placenta delivers after each puppy. Count them. A retained placenta is a vet emergency.
Call the vet immediately if any of these happen
Move straight to emergency surgery.
Stalled labour or uterine inertia. Tiny dams fatigue fast.
Green (uteroverdin) signals placental separation. A puppy is in distress[26].
Low blood sugar (hypoglycaemia) or low blood calcium (eclampsia). Toy breeds are at highest risk.
Pomeranian-specific newborn priority: hypoglycaemia. Pomeranian puppies are tiny, often well under 4 ounces (113 g) at birth. Their glycogen reserves are small, and a missed feed of 6 to 8 hours can drop their blood sugar to a life-threatening level. Weigh every puppy three times a day for the first two weeks; any puppy that drops weight or skips a feed needs immediate warming and supplemental feeding with a commercial puppy milk replacer.
Cow milk is not a substitute and causes diarrhoea. A healthy Pomeranian puppy gains 5 to 10 percent of birth weight per day in the first two weeks.
Our dog breeding compatibility calculator projects whelping dates from a known mating day. Also see our broader step-by-step ethical breeding guide for a full pre-whelping checklist.
The AKC recognises one Pomeranian breed with one published size standard: 3 to 7 pounds (1.4 to 3.2 kg) at adulthood[1]. The American Pomeranian Club's position is direct: there is no such thing as a Teacup, Miniature, or Throwback Pomeranian[15].
"Teacup Pomeranian" is a marketing label for dogs deliberately bred below the breed standard, often under 3 lb adult weight. It is not a separate breed and AKC does not register it as a separate variety. Dogs bred for under-standard size carry elevated hypoglycaemia, fragile-bone, dental-crowding, and organ-development risks.
Dogs deliberately bred below 3 lb face the same toy-breed health risks as below-standard Shih Tzus: hypoglycaemia, fragile bones, dental crowding, underdeveloped organs, and shorter lifespan[15]. If you want to ship the AKC standard, pair two in-standard Pomeranians (3 to 7 lb) with full APC clearances. Do not pair the smallest dogs in your pedigree to chase a price premium.
For a sibling-breed comparison, our Shih Tzu breeding guide covers the equivalent "Imperial vs AKC standard" debate in a brachycephalic toy.
Health-risk thresholds (adult weight)
Merle warning: never pair two merles
Merle is a dominant gene. A merle Pomeranian carries the gene from at least one parent[16]. Single-merle (Mm) dogs bred to non-merle (mm) mates produce a normal litter with no genetic compounding.
Pairing two merles produces double-merle (MM) puppies. One published study reported that around 25 percent of double-merle dogs are deaf in one or both ears, compared with about 3.5 percent of single-merle dogs. Double-merles also have a very high incidence of microphthalmia (abnormally small eyes) and other ocular defects.
Merle is not an accepted color in the AKC Pomeranian breed standard[16]. Some breeders argue the gene was introduced into the breed from outside populations. Either way, do not pair two merles. If one parent is merle, the other must be a non-merle (mm).
Body size is not a breeding goal in a healthy programme. Pick parents in standard, with passing clearances and a clear merle status. Let size and colour fall where the genetics naturally land.
Clauses every Pomeranian stud contract should name
Put the stud deal in writing before the first mating. The American Breeder template covers the parts above[18]. Both owners sign and keep a copy. Verbal agreements are the main reason stud deals end in arguments.
No. Pomeranian females can come into their first heat as early as 4 to 8 months, but they are not skeletally or mentally mature. Most parent-club guidance recommends waiting until at least 18 months and the third heat cycle. Earlier mating raises the risk of dystocia, hypoglycaemia in the dam, smaller litters, and poor maternal care.
A Pomeranian litter averages 1 to 3 puppies, with rare litters reaching 5 to 7. First litters are usually smallest (1 to 3). The tiny litter size means a single bad whelping can wipe out the litter's margin, which is one reason Pomeranian breeding cost-to-revenue economics are the tightest in the v7 toy lineup.
Pomeranian pregnancies last about 63 days from ovulation, with a normal range of 58 to 68 days. A reproductive vet can confirm pregnancy by ultrasound around day 28 and count puppies by X-ray around day 55. Roughly 98% of Pomeranians deliver naturally, so a planned C-section is not the default, although emergency surgery should be budgeted for.
No. The AKC recognises one Pomeranian breed with a published size standard of 3 to 7 pounds. "Teacup", "Miniature", and "Throwback" are marketing labels for dogs bred deliberately below the breed standard (often under 3 lb). The American Pomeranian Club's position is unambiguous: there is no such thing as a Teacup Pomeranian, and below-standard dogs face elevated hypoglycaemia, fragile-bone, and organ-development risks.
Yes. The American Pomeranian Club requires a cardiac evaluation (either a congenital cardiac exam or an advanced echocardiogram) for any dog being CHIC-certified. Pomeranians are in the highest-risk category for Patent Ductus Arteriosus (PDA), the most common congenital heart defect in dogs. If both parents have a history of PDA, incidence in the litter can reach 80%.
Alopecia X shows a strong familial pattern and is suspected to be inherited, with active research into a chromosome-15 marker, but no validated DNA test exists as of 2026. The American Pomeranian Club's working guidance is to research pedigrees, avoid breeding lines with documented Alopecia X, and breed only from dogs older than the typical onset age (around two years).
No. Breeding two merle Pomeranians (MM x Mm or Mm x Mm) is strongly discouraged. Double-merle puppies show roughly 25% deafness in at least one ear vs about 3.5% in single-merle dogs, and a high rate of microphthalmia and other ocular defects. A single merle (Mm) bred to a non-merle (mm) is the only genetically safe combination. Note that merle is not an accepted color in the AKC Pomeranian breed standard.
Early signs include a calmer mood, slight nipple swelling, and a small drop in appetite around week three. The reliable confirmation is an ultrasound at day 28, followed by an X-ray at day 55 to count puppies. Home pregnancy tests for dogs are not reliable.
Most US states require puppies to stay with their mother and littermates until at least eight weeks of age. Many Pomeranian breeders wait until 10 to 12 weeks because the breed's tiny size makes early hypoglycaemia management critical, and the extra time on the mother improves immunity, feeding stability, and thermoregulation.
Typical US prices run $2,500 to $4,500 from a health-testing breeder, $4,500 to $6,000 for champion lineage, and higher still for rare colours or marketed "Teacup" dogs. Pet-line puppies from smaller-scale breeders can be found at $600 to $2,000. Puppies without OFA patellas, cardiac, and CAER eye clearances on the parents should cost much less because the buyer takes on the health risk.
