Longevity
Life expectancy
With a life expectancy of 12 to 14 years, the Welsh Terrier is one of the small dogs that can accompany their family for many years. This longevity depends on a suitable diet, a stable weight, regular exercise and constant health monitoring.
Constitution
Is this a robust breed?
The Welsh Terrier copes well with an active life and shows generally rather good robustness. Its sturdiness must not make one forget monitoring of the eyes, the thyroid and the locomotor system, especially in the event of a family history.
Things to watch for
What to look out for
Particular attention must be paid to orthopedic, ophthalmological, neurological, skin and endocrine disorders reported in the breed. Regular observation of gait, skin, vision and behavior helps to detect abnormalities early.
Epilepsy: A predisposition exists in the breed and justifies a prompt veterinary evaluation in case of seizure, loss of consciousness, or unusual neurological behaviors.
Glaucoma: This eye condition can threaten vision and requires early management in case of a painful, red, or cloudy eye.
Hip and elbow dysplasia: These joint disorders can cause lameness, stiffness, and discomfort during exertion, even in a small-sized dog.
Hypothyroidism: A decrease in thyroid function can promote fatigue, weight gain, skin disorders, and a decline in overall condition.
Legg-Calvé-Perthes disease: This condition affecting the femoral head causes pain and lameness and may require orthopedic management.
Allergies and dermatomyositis: Skin problems or a cutaneo-muscular inflammation may appear and deserve monitoring in case of lesions, itching, or skin sensitivity.
Climate
Tolerance to cold and heat
The Welsh Terrier is not among the breeds most comfortable in extreme climates. It is advisable to avoid sustained exertion in high heat and not to leave it motionless for too long in cold or damp weather, even if its dense coat provides it with some protection.
Weight
Prone to weight gain
Weight gain is not its main weak point, but a less active lifestyle or treats that are too frequent can quickly throw its compact silhouette off balance. Maintaining a stable weight relies on measured portions, counted treats, and daily physical activity.
Everyday care
Good habits to keep your pet healthy
- Schedule regular veterinary follow-up with eye checks.
- Monitor any limping, stiffness, or decreased ease during exertion.
- Observe the skin and coat in case of itching or lesions.
- Maintain a stable weight to protect the joints.
Vaccination
Welsh Terrier vaccinations: schedule
Which vaccines does a Welsh Terrier need? Like all dogs, Welsh Terriers should receive their core vaccines from 8 weeks of age: CHPPi (core vaccine) and Leptospirosis. Puppies receive their initial Welsh Terrier vaccinations in several shots spaced 4 weeks apart, followed by a first booster at 1 year. Depending on their lifestyle (hunting, hiking, boarding, travel, region), your veterinarian may add vaccines against Rabies, Kennel cough, Piroplasmosis, Lyme disease and Leishmaniasis.
| Vaccine | Primary vaccination | First booster | Then | For whom? |
|---|---|---|---|---|
CHPPi (core vaccine)Core Distemper, Rubarth hepatitis, parvovirosis and parainfluenza | 8 weeks · 12 weeks · 3 months | 1 year | every year | All animals |
LeptospirosisCore Leptospirosis (bacterium transmitted by rodent urine and stagnant water) | 8 weeks · 12 weeks | 1 year | every year | All animals |
RabiesDepending on lifestyle Rabies | 12 weeks | 1 year | every year | Mandatory for travel abroad, categorized dogs, most boarding kennels and shows |
Kennel coughDepending on lifestyle Bordetella bronchiseptica and parainfluenza | 8 weeks | 1 year | every year | Dogs attending boarding kennels, daycares, dog clubs and shows |
PiroplasmosisDepending on lifestyle Tick-borne babesiosis | 5 months · 6 months | 1 year | every year | Hunting dogs, dogs living in rural or wooded areas, dogs highly exposed to ticks |
Lyme diseaseDepending on lifestyle Tick-borne borreliosis | 12 weeks · 3 months | 1 year | every year | Hiking dogs, hunting dogs, forest areas of the East and the Center |
LeishmaniasisDepending on lifestyle Leishmaniasis transmitted by sandflies | 6 months | 1 year and 6 months | every year | Dogs living or staying in the South of France, Corsica and the Mediterranean basin |
Adult Welsh Terrier booster shots are given annually for leptospirosis and rabies. For distemper, hepatitis, and parvovirus, a booster every three years is often enough after the first booster. Your veterinarian will tailor the schedule to your dog's actual risk.

Choosing well
Adopting a healthy Welsh Terrier
Regular veterinary follow-up with eye examinations is recommended, as well as monitoring thyroid function if compatible signs appear. In case of lameness, stiffness or exercise intolerance, an orthopedic assessment should be considered without delay.
