Do you breed Jugs? Caninebreeder.co.uk is an independent UK directory where you can list your kennel, advertise Jug puppies for sale and promote a Jug stud dog, or the pedigree Jack Russell Terrier or Pug you breed from. People researching this cross want to see health results for both parents, especially the Pug parent's breathing grade. Your listing gives you room to show them alongside your licence number, planned litters and contact details, so the right buyers can find you.

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.

Is my listing already here?

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 Jug

The Jug is a cross between a Jack Russell Terrier and a Pug, and is sometimes advertised as a Jackpug. It is not a breed recognised by the Royal Kennel Club (RKC), so it has no breed standard, no Breed Watch category and no place on the RKC Breed Register. The two parent breeds are the best guide to what a Jug may be like. The RKC explains that a crossbreed shows a blend of its parents' traits that can come out in many ways, so littermates may not look or behave alike.

The parent breeds. The Jack Russell Terrier descends from the small working terriers of Britain and Ireland, was shaped into a show dog in Australia and was recognised by the RKC in 2016. It is a hunting terrier built to go to ground, and its breed standard asks for a bold, fearless, friendly and confident temperament. The Pug is a Toy breed believed to have come to Europe from China with Dutch traders, and it was bred only as a companion. The RKC describes Pugs as affectionate and sociable, sometimes strong-willed in training, and inclined to become anxious when left alone for long spells.

Size and build. Both parents are small. The Jack Russell standard gives a height of 25 to 30 cm, and the Pug standard an ideal weight of 6.3 to 8.1 kg. A Jug will usually be a small, sturdy dog, but no crossbreed has a fixed size.

Coat and grooming. Both parents shed, and the RKC suggests grooming each about once a week. The Pug coat is short and smooth, while a Jack Russell's may be smooth, broken or rough, so a Jug's coat can vary too.

Exercise. The RKC suggests up to an hour a day for both breeds. If a Jug has a shorter, Pug-like muzzle, keep exercise gentle in warm weather, because the RKC warns that a flat face limits a dog's tolerance of heat and hard exertion.

Temperament and suitability. Expect some mix of terrier alertness and hunting instinct with a companion dog's wish to be close to people. The RKC rates both parents as suitable for a flat, though it lists the Jack Russell as a country dog and the Pug as suited to town or country. A Jug is likely to suit a household where someone is at home for much of the day.

Jug health tests

The RKC sets no health tests for the Jug itself, so screening should follow what it recommends for each parent breed. For the Jack Russell, Good Practice is a DNA test for primary lens luxation (PLL), a painful eye condition that can lead to blindness. Best Practice adds DNA tests for two balance disorders, late onset ataxia (LOA) and spinocerebellar ataxia (SCA), plus an eye examination. For the Pug, Good Practice is a breathing assessment for brachycephalic obstructive airway syndrome (BOAS) under the RKC and University of Cambridge Respiratory Function Grading (RFG) scheme, together with an eye examination. Best Practice adds the DNA-based risk test for Pug dog encephalitis (PDE) and hip scoring.

PLL and LOA are autosomal recessive, and the RKC suggests SCA is inherited the same way, so a puppy is affected only if it inherits the faulty gene from both parents. In a first cross, a Jack Russell parent that tests clear cannot pass on the variants tested for. Where both parents are Jugs, both need testing. The RFG scheme is open only to a set list of breeds, which includes the Pug but not the Jug, while the BVA eye and hip schemes accept crossbreeds. Whatever a Jug's face shape, watch for noisy breathing or heavy panting.

  • Jack Russell parent, Good Practice: DNA test for primary lens luxation (PLL)
  • Jack Russell parent, Best Practice: DNA test for late onset ataxia (LOA)
  • Jack Russell parent, Best Practice: DNA test for spinocerebellar ataxia (SCA)
  • Jack Russell parent, Best Practice: Eye testing using the BVA/KC/ISDS Eye Scheme
  • Pug parent, Good Practice: Breathing testing for BOAS using the Respiratory Function Grading (RFG) scheme
  • Pug parent, Good Practice: Eye testing using the BVA/KC/ISDS Eye Scheme
  • Pug parent, Best Practice: DNA test for Pug dog encephalitis (PDE), which the RKC treats as a risk test
  • Pug parent, Best Practice: Hip testing using the BVA/KC Hip Dysplasia Scheme
  • Breed Watch: none for the Jug (not a recognised breed); Jack Russell Terrier Category 1; Pug Category 3 (points include signs of breathing difficulty, pinched nostrils, protruding eyes, skin-fold dermatitis and being too fat)

Choosing a Jug breeder

A good Jug breeder starts with two healthy, even-tempered parents and can show you the health results for each. For the Pug parent, that means a current RFG breathing grade (the RKC advises regrading every two years) and an eye certificate. For the Jack Russell, expect PLL, LOA and SCA DNA results and an eye certificate. Where a parent is RKC registered, you can confirm its results on the Health Test Results Finder.

The RKC advises buyers to see the mother with her puppies and to ask about the father and the breed-related tests both parents have had. A careful breeder will be frank about how much a cross can vary in size, coat and face shape, and will not promise that any puppy will breathe easily. They will raise the litter in the home, begin socialisation early and ask about your routine. Puppies must be microchipped and registered on a database by eight weeks old. In England, a breeder needs a council licence to breed three or more litters in 12 months and sell any of the puppies, or to run a business breeding and advertising dogs for sale, and must show the licence number in adverts.

  • Can I see both parents' health certificates, including the Pug's current RFG grade?
  • What are the Jack Russell parent's PLL, LOA and SCA results, and if both parents are Jugs, have both been tested?
  • Can I meet the mother, and how do both parents breathe after exercise?
  • How have the puppies been socialised, and how do they cope with short spells alone?
  • Will you take the dog back at any age if I can no longer keep it?

Jug questions

Is the Jug a Royal Kennel Club recognised breed?

No. The Jug is a crossbreed of the Jack Russell Terrier and the Pug, so it has no RKC breed standard and cannot be shown at breed shows. The RKC's Activity Register is open to crossbreeds, however, and a registered Jug can take part in agility, obedience, rally, flyball and other licensed events.

Do Jugs have breathing problems?

Some may. The Pug is a flat-faced breed, and the RKC recommends breathing assessment for BOAS for Pugs used in breeding. A Jug can inherit a longer or shorter muzzle, so there is no guarantee either way. Ask to see the Pug parent's RFG grade and watch for noisy breathing, heavy panting or tiring quickly. The RKC reports that some flat-faced dogs run over twice the heatstroke risk of other dogs.

How much exercise does a Jug need?

The RKC suggests up to an hour a day for both the Jack Russell Terrier and the Pug, so a Jug will usually need about the same, split into walks and play. Adjust to the individual dog, and keep exercise gentle in warm weather if your Jug has a shorter face.

Do Jugs shed?

Yes, they are likely to. The RKC lists both parent breeds as shedding, with grooming about once a week. A weekly brush helps manage loose hair, whether the coat is smooth or a little rougher.
