European Pug Breeders Network · Est. 2014

A genetic registry that keeps the pug breed healthy.

Mops.dog unites 420+ certified European pug kennels in one cooperative platform: DNA-verified pedigrees, hereditary disease screening, inbreeding control, breeding-pair compatibility and a continent-wide veterinary consultation network.

Members in 24 European countries · Accredited by 6 national kennel clubs · GDPR-compliant data handling

Why Mops.dog

A cooperative platform, not a directory

Built by working breeders and veterinary geneticists for the people who actually shape the next generation of the breed.

DNA

Verified pedigrees

Every registered dog is linked to a swab-confirmed DNA profile. Pedigrees are cryptographically signed by the issuing kennel and cross-checked against parents in the database.

COI

Inbreeding control

Real-time Coefficient of Inbreeding for any proposed pairing, projected over 5 / 8 / 10 generations. Avoid blind matings — and document due diligence for buyers and clubs.

RX

Hereditary disease screen

One unified panel for 23 pug-relevant markers: PDE / NME, PDP1, hemivertebrae, brachycephalic obstructive airway syndrome predisposition, hip dysplasia, eye conditions, and more.

RM

Relatedness finder

Search the registry to find — or deliberately avoid — relatives of a given dog across all member kennels. Outcross planning is one query, not a month of emails.

VET

Veterinary consultation

Access a network of 70+ veterinarians specialising in brachycephalic and toy breeds. Submit cases, exchange opinions, and book second-look reviews from your dashboard.

REC

Kennel record-keeping

Litters, vaccinations, BOAS grading, weight curves, contracts and buyer handoff documents — kept in one auditable place per kennel, exportable on demand.

DNA & genetics

From swab to breeding decision

A complete workflow from sample collection through laboratory analysis to actionable breeding recommendations.

01

Sample collection

Order swab kits in bulk from your kennel dashboard. Pre-paid postage, EU-wide chain of custody, automatic linking to the dog's registry file on lab intake.

02

Laboratory panel

Three partner labs across the EU run the unified pug panel: 23 disease markers, 14 coat & morphology loci, and parentage SNPs. Results signed and uploaded directly.

03

Compatibility search

Enter a sire and find every available dam in the network that is genetically suitable: low projected COI, no shared disease-allele risk, complementary phenotype.

04

Outcross planning

For populations getting too narrow, request introductions to confirmed unrelated lines in other countries. We mediate, you decide.

05

Carrier disclosure

Carriers are not hidden. They are flagged and matched only with clears — preserving genetic diversity while never producing affected puppies.

06

Buyer transparency

Every puppy goes home with a one-page genetic certificate, signed by the kennel and verifiable via QR against the registry.

Health registry

The data layer the breed has been missing

Anonymized, longitudinal health data from member kennels — used to track real outcomes, not just kennel-club rumor.

Research & population

Population studies, openly published

Member kennels contribute data; geneticists publish findings; the breed benefits. We close the loop.

Population structure 2025

Effective population size (Nₑ) of European pugs estimated at 124 — below the FCI recommended floor of 200. Outcross programs are no longer optional; they are the only sustainable path.

BOAS trend (2018 → 2024)

Selective breeding against extreme brachycephaly across member kennels reduced BOAS grade ≥2 from 41.8% to 28.6% in seven years. The peer-reviewed protocol is open.

NME / PDE marker validation

Joint study with three EU veterinary schools confirms predictive value of the DLA-DRB1 haplotype combination. Used since 2022 to retire carrier-carrier pairings from the network.

“Before we joined, we were guessing. Now every breeding pair gets a projected COI, a carrier report and an MRI status before the appointment is even booked. It changed how I run the kennel.”

Dr. Annelies Vermeervan der Lindenhoeve · Utrecht, NL

“The relatedness search saved a litter we were about to plan. The dam and sire turned out to share a great-grandsire we didn't see in the paper pedigree. That kind of mistake is what this registry prevents.”

Carlo BianchiCasa dei Mopsi · Bologna, IT

“As a veterinarian I needed actual numbers — not folklore — to advise breeders. Mops.dog gives me population-scale rates I can quote in a consultation.”

Dr. Stefan Maier, DECVNVeterinary Neurology · Munich, DE
