History and origin

The Billy was created in the 19th century by Gaston Hublot du Rivault and is named after his home, the Château de Billy in Poitou. He started from three old Poitevin lines: Montemboeuf, Ceris and Larrye. Du Rivault chose the lighter-coloured dogs.

The pack was dispersed in 1927, and after the Second World War only two dogs survived. His son, Anthony, rebuilt the breed using the Poitevin, Porcelaine and Harrier.

Physical characteristics

The Billy is a well-built, strong but light hound. The front of the body is stronger than the rear.

General appearance

The eyes are lively, large and dark. The medium-sized ears are set fairly high for a French hound. The tail is long and strong. The standard calls for an easy gallop on the move.

Training and socialisation

The Billy is a pack dog, bred for hunting. It is trained in the pack, with patience and consistency.

It is not a breed for life as a city companion dog.

Tips for effective training

  • Keep it in company. It is used to living in a pack.
  • Practise the recall. On a trail, it may forget commands.
  • Use rewards. Praise and food motivate it.
  • Let it work with its nose. Tracking games use its talent.

Activity needs and lifestyle

It is a hardy hunter that needs a lot of exercise and space. A few packs are still used today to hunt roe deer and wild boar.

Activity How often Why it matters
Long walks in nature daily Its stamina calls for a lot of exercise
Scent work several times a week Uses its hound instinct
Time with other dogs daily It is a pack dog

Tips for a balanced life

  • It is best suited to hunters.
  • It needs a large, fenced garden.
  • Keep it on a lead outside the yard.

Care and health

Coat and skin care

The short, harsh coat is easy to look after, with brushing once a week.

Common health problems

There are no known hereditary diseases specific to the breed. As with any large, active dog, its joints are worth watching.

Condition Description Common symptoms
Hip dysplasia The hip joint forms incorrectly and, over time, arthritis develops Limping, difficulty getting up or jumping, hip pain

Other care

  • Check the ears after every outing.
  • Look for ticks in the white coat after hunting.
  • Trim the nails when they start to touch the floor.

Diet and nutrition

A large hound that hunts needs a lot of energy during the season. Adjust the portion to its workload and weight.

Tips for a healthy diet

The table gives a starting estimate, calculated with the formula from the Merck Veterinary Manual. The first two calorie columns show the calories per day for a healthy adult dog. The last column shows what this means in dry food with 3,500–4,000 kcal per kilogram.

Dog's weight Calories per day (neutered) Calories per day (not neutered) Dry food per day (approximate)
33 kg 1,540 kcal 1,730 kcal 380–490 g
40 kg 1,780 kcal 2,000 kcal 440–570 g
47 kg 2,010 kcal 2,260 kcal 500–650 g
  • Give it its food in two meals a day to reduce the risk of bloat.
  • Fresh water should always be available.
  • A dog is at the right weight when you can feel its ribs without pressing hard.

Foods to avoid

Some human foods are dangerous for dogs: chocolate, coffee, grapes and raisins, onions, garlic, xylitol (a sweetener used in chewing gum), macadamia nuts and alcohol.

Reproduction and development

Physical and emotional maturity

In dogs, sexual maturity usually comes between 6 and 12 months, but in large breeds it can be delayed until about two years. The body also reaches its adult form later than in small breeds.

Mating and pregnancy

Pregnancy lasts about 63 days, counted from ovulation. Mating a female on her first heat is not recommended. The FCI standard requires that only healthy dogs of typical breed appearance are used for breeding.

Caring for the puppies

In large breeds, a litter has around 7 puppies on average. Socialisation starts in the first weeks: gentle handling, everyday noises and new people.
