Pomeranian Health Issues: A Complete UK Owner's Guide

Pomeranians are prone to several genuine breed-specific health issues — but one is strikingly overrepresented in the UK specifically: Pomeranians made up 46.7% of UK referral cases for atlantoaxial subluxation, a serious neck instability condition, compared to around 10% in Japan and the US.

This guide covers the real health picture for the breed, including conditions most generic content glosses over.

Breed Overview

The Pomeranian is a toy breed descended from larger Spitz-type sledge dogs, standing around 15–19cm at the shoulder and weighing just 1.9–3.5kg. Despite their tiny size, Pomeranians are typically bold, alert, and confident, often unaware of how small they actually are.

Their thick double coat, prized for its fluffy appearance, sheds heavily and needs regular grooming to prevent matting.

Atlantoaxial Subluxation — A UK-Specific Overrepresentation

This is worth covering in detail because it's a genuinely striking, UK-specific finding that's largely absent from generic breed content.

Atlantoaxial subluxation (AAS) is an instability between the first two neck vertebrae (the atlas and axis), often due to a malformed or absent dens (a small bony peg that normally helps stabilise the joint) — it can cause neck pain, and in more severe cases, spinal cord compression leading to weakness, wobbliness, or paralysis.

Case-series data comparing referral clinics found Pomeranians made up 46.7% of AAS cases in the UK, compared with roughly 10–11% of cases in Japan and the US.

Researchers haven't fully explained this regional disparity, but it's a genuine, documented pattern rather than a coincidence — and it means UK Pomeranian owners specifically should take neck pain, reluctance to move the head, or sudden hind- or fore-leg weakness seriously and seek prompt veterinary assessment rather than assuming it's a minor strain.

Diagnosis and Treatment Options for AAS

Diagnosing AAS reliably can be genuinely challenging, and usually involves neck X-rays or advanced imaging (CT or MRI) to assess the alignment of the atlas and axis and the condition of the dens. There are two main management routes, and it's worth understanding both before a diagnosis happens rather than in the middle of a crisis.

Conservative treatment involves strict cage rest and a rigid neck brace or splint, often for six to eight weeks, alongside pain relief; one study found this approach led to a good long-term outcome in roughly 62% of acute cases (symptoms present less than 30 days), though a neck brace is genuinely difficult to maintain and poorly tolerated by many dogs, and pain or spinal cord issues can recur once it comes off.

Surgery aims to permanently stabilise the joint, typically using bone screws and surgical cement to fuse the atlas and axis, and is generally recommended when signs are more severe or conservative treatment hasn't worked — reported success rates range from roughly 61–91%, with notably better outcomes in younger dogs, more acute cases, and dogs that can still walk before surgery.

Chronic cases (symptoms present for more than 30 days) tend to have a meaningfully worse prognosis than acute ones under either approach, which is another reason prompt veterinary assessment for any sudden neck pain or weakness genuinely matters for this breed.

Luxating Patella — The Highest Prevalence of Any Breed

An English study measuring patellar luxation (a dislocating kneecap) across breeds found a 6.5% prevalence in Pomeranians — the highest of any breed included in that study.

The condition typically becomes evident between 4 and 6 months of age and can range from an occasional, self-resolving "skip" to a permanently dislocated kneecap requiring surgical correction in moderate-to-severe cases.

Watch for a dog that occasionally holds up a back leg while running, then resumes normal movement a few strides later — a classic early sign worth mentioning to your vet even if it seems to resolve on its own.

Tracheal Collapse

Pomeranians are one of several small breeds genuinely predisposed to tracheal collapse, where the cartilage rings supporting the windpipe weaken or flatten, causing a distinctive dry, honking cough, often worse with excitement, exercise, or pulling on a collar. Referral-clinic data has found Pomeranians represent a meaningfully above-average share of tracheal collapse cases.

Mild cases are often managed with weight control, a harness instead of a collar, and cough-suppressant medication, while severe cases may need surgical stenting.

Alopecia X ("Black Skin Disease")

Pomeranians are strikingly overrepresented in cases of Alopecia X, a poorly understood hormonal/hair-cycle disorder causing symmetrical hair loss (often starting around the neck and body, sparing the head and legs) and sometimes darkened skin in affected areas — in one referral-clinic case series, Pomeranians made up nearly 80% of the caseload.

It's a cosmetic rather than a painful or dangerous condition, but it can be distressing for owners, and diagnosis usually involves ruling out other causes of hair loss (thyroid disease, Cushing's disease) first, since Alopecia X is essentially a diagnosis of exclusion.

Dental Disease and Retained Baby Teeth

Like many toy breeds, Pomeranians' small jaws mean teeth are often crowded, making periodontal disease and early tooth loss genuinely common.

This breed is also genuinely prone to retained deciduous (baby) teeth, where an adult tooth erupts without the baby tooth falling out first — the two teeth then sit side by side, trapping food and plaque between them and accelerating gum disease around both.

If a breeder or vet mentions retained baby teeth at a puppy check, it's worth taking seriously rather than assuming it will sort itself out; extraction (often at the same time as neutering, if that's planned) is the usual fix.

Daily brushing where possible, alongside regular professional dental checks, matters more for this breed than most, and persistent bad breath or visible tartar shouldn't be dismissed as normal for a small dog.

Eye Conditions

Pomeranians can be affected by progressive retinal atrophy and cataracts, both of which responsible breeders screen for. Watch for cloudiness, reluctance to move confidently in dim light, or bumping into furniture, and raise any changes with your vet.

Toy-Breed Size Risks Worth Knowing

Beyond specific diagnosable conditions, a Pomeranian's very small size carries some genuine practical risks worth knowing, particularly in puppies.

Hypoglycaemia (low blood sugar) is a real risk in toy-breed puppies, who have less reserve capacity than larger dogs, and can present as weakness, wobbliness, or lethargy, particularly if a meal is missed — frequent small meals are commonly recommended for young toy-breed puppies for this reason.

Their small size also means genuinely elevated injury risk from falls, being stepped on, or rough handling by children, which is worth factoring into a household with young kids or larger, boisterous dogs. None of this means a Pomeranian is fragile in daily life, but it's worth being genuinely mindful of, especially in the first year.

Lifespan

Pomeranians typically live 12–16 years, among the longer lifespans of any breed, though this makes proactive management of their genuine breed-specific risks — particularly neck, joint, and airway health — all the more worthwhile over what's often a long life together.

Keeping Your Pomeranian Healthy

  • Use a harness, not a collar — reduces pressure on both the trachea and the neck, relevant to both tracheal collapse and AAS risk
  • Take neck pain or sudden weakness seriously — given the UK-specific AAS overrepresentation, don't assume it's a minor strain
  • Watch for intermittent back-leg skipping, an early sign of luxating patella
  • Daily dental brushing and prompt attention to any retained baby teeth flagged by your vet
  • Frequent small meals for puppies, given genuine toy-breed hypoglycaemia risk
  • Weight management — reduces strain on both joints and the airway
  • Annual vet checkups, with attention to gait, coat changes, and breathing

Supporting Your Pomeranian's Health

Given this breed's genuine predisposition to luxating patella, our Hip & Joint Chews (glucosamine, chondroitin, MSM, turmeric and green-lipped mussel) can be a useful part of a Pomeranian's routine, particularly from middle age. Our Probiotic Chews may also help support digestive and skin health.
