Is it free to advertise here?

Yes. A breeder profile and your litter and stud dog adverts are free. Premium profiles, featured placement and sponsored articles are optional paid extras; see pricing.

Do I need a licence to advertise puppies?

In England you need a dog breeding licence from your council if you breed three or more litters in 12 months or breed and sell dogs as a business, and Wales, Scotland and Northern Ireland have their own schemes. Licensed breeders show their licence number and issuing council on every advert. Puppies must be at least eight weeks old before they go to new homes.

We add licensed breeders from councils' public registers. Search for your kennel name; if it is listed you can claim it and edit everything.

About the Pyrenean Mastiff

The Pyrenean Mastiff is a flock guardian from the Pyrenees between Aragon and Navarra in northern Spain, placed by The Royal Kennel Club in its Working group. The RKC says it was once called the Navarra Mastiff and belongs to the Molosser family of heavy guarding dogs. It protected flocks from wolves and bears, often wearing a heavy spiked collar to shield its neck and throat. The breed is on the RKC Imported Breed Register, which holds newly recognised breeds not yet well established in the UK, hence "(Imp)" in its official name. It is a separate breed from the Pyrenean Mountain Dog in the Pastoral group. Other large guarding breeds include the Mastiff, Tibetan Mastiff and Anatolian Shepherd Dog, or browse all Working group breeders.

Size and build. The breed standard describes a very large, strong, muscular dog with solid bone, a little longer in the body than it is tall at the withers. Minimum heights are 77 cm (30¼ in) for dogs and 72 cm (28¼ in) for bitches, with no upper limit. The neck carries a distinct double dewlap, and double hind dewclaws are preferred, though single or absent ones are allowed.

Coat and grooming. The coat is dense, thick and bristly rather than woolly, ideally 6 to 9 cm along the middle of the back and longer on the neck, shoulders, belly, tail and backs of the legs. The base colour is white with a well-defined mask, sometimes with patches in the mask colour; medium grey is preferred, followed by shades such as golden yellow, brown, black, silver-grey and beige. The RKC suggests grooming every day and notes that the breed sheds.

Exercise and home. The RKC lists up to an hour of exercise a day, a large house and a large garden, in town or country, and a lifespan of under 10 years.

Temperament and suitability. The standard describes a calm, noble, intelligent dog that is friendly towards people, confident with strangers and good-natured with other animals, guarding only when necessary. The RKC breed page adds that it can be aggressive when doing the guarding job it was bred for, while staying loyal to its family. Its size and guarding instincts call for space and secure boundaries. For its working roots, see our guide to livestock guardian dogs.

Pyrenean Mastiff health tests

The RKC Pyrenean Mastiff page currently lists no Good Practice or Best Practice pre-breeding health screening for the breed, and no breed-specific breeding restrictions. There is no RKC DNA testing package for the breed, although individual DNA tests are available. The breed is in Breed Watch Category 1, meaning no visible concerns linked to conformation have been flagged for show judges beyond the breed standard itself. The RKC is moving its breed health work into a new breeding for health framework covering genetic diversity, conformation and breed-related disease, so check the breed page from time to time for changes.

No listed screening is not the same as a clean bill of health. The BVA hip and elbow dysplasia schemes screen dogs of all breeds, so ask whether the parents have been hip scored or elbow graded, and look up any recorded results on the RKC Health Test Results Finder. With the breed still on the Imported Breed Register, also ask for the coefficient of inbreeding of the mating and where the parents' bloodlines were imported from.

Health and registration points for the Pyrenean Mastiff (RKC):

  • Recommended pre-breeding health screening (Good Practice or Best Practice): none listed at present
  • DNA testing: no breed-specific RKC package; individual DNA tests available
  • Not RKC-listed for this breed, but open to any breed if a breeder chooses: BVA/KC Hip Dysplasia Scheme; BVA/KC Elbow Dysplasia Scheme
  • Breed-specific breeding restrictions: none at present
  • Breed Watch: Category 1
  • Register status: RKC Imported Breed Register

Choosing a Pyrenean Mastiff breeder

There is no RKC-listed health screening for the Pyrenean Mastiff, and the RKC Find a Club search showed no registered breed club for it when we checked in September 2026, so a lot rests on how open the breeder is. A careful breeder will tell you about the health, age and temperament of the parents and their relatives, share any hip or elbow results, give you the coefficient of inbreeding and explain where the bloodlines came from. They should be frank about the space, fencing and handling a guardian of this size needs, and ask as many questions about your home as you ask them. See the puppies with their mother where they were raised: under Lucy's Law, puppies in England must be bought directly from the breeder or adopted from a rescue centre, not from a third-party seller. In England a council licence is needed to breed three or more litters in any 12 months and sell any of the puppies, or to run a business breeding dogs and advertising them for sale. Every puppy must be microchipped and registered on a database by eight weeks old. Our buyer safety guide covers deposits and scams.

Questions to ask a Pyrenean Mastiff breeder:

  • Can I see the puppies with their mother, and meet the father if he is nearby?
  • Have the parents been hip scored or elbow graded, and are the results recorded with the RKC?
  • What is the coefficient of inbreeding for this litter, and where were the parents' lines imported from?
  • How have the puppies been socialised with visitors, other dogs and everyday household noise?
  • Will the puppy be RKC registered and microchipped, and will you take it back if it ever needs a new home?

Pyrenean Mastiff questions

Is the Pyrenean Mastiff the same breed as the Pyrenean Mountain Dog?

No. The RKC recognises them as separate breeds. The Pyrenean Mastiff is a Molosser-type flock guardian developed between Aragon and Navarra, placed in the Working group and on the Imported Breed Register. The Pyrenean Mountain Dog is a white guardian breed in the Pastoral group with its own breed standard, which calls for strongly made double dewclaws on each hind leg.

How big is a Pyrenean Mastiff?

Very big. The breed standard sets minimum heights of 77 cm (30u00bc in) for dogs and 72 cm (28u00bc in) for bitches, with no upper limit, and the RKC breed page gives ideal heights of about 81 cm for males and 73.5 cm for females. The RKC recommends a large house and a large garden.

What health tests should Pyrenean Mastiff parents have?

The RKC currently lists no recommended pre-breeding screening for the breed, and it is in Breed Watch Category 1. The BVA/KC hip and elbow schemes are open to any breed, so ask whether the parents have been screened, check any results on the RKC Health Test Results Finder, and ask for the coefficient of inbreeding of the litter.

Why does the RKC call the breed 'Pyrenean Mastiff (Imp)'?

The breed is on the RKC Imported Breed Register. The RKC explains that breeds with Imp after their name are newly recognised and not yet well established in the UK, and they stay on this register until the RKC considers them ready to move to the main Breed Register. Under RKC policy, dogs on this register can take part straight away in obedience, agility, rally, flyball, heelwork to music, handling and working trials. At other licensed events they are restricted to companion dog shows, matches and particular classes, and only after an interim breed standard has been published.
