Longevity
Life expectancy
The life expectancy of the Harrier is generally between 12 and 14 years, which is decent for a scenthound of this size. A balanced diet, a stable weight, regular physical activity and serious veterinary follow-up help preserve its longevity.
Build
A robust breed?
The Harrier is considered a rather robust breed. It tolerates exertion well when it is properly conditioned, but its good natural endurance does not exempt it from monitoring its weight, joints and the condition of its ears.
Watch points
What to watch for
As with many active scent hounds, prevention involves good overall care, monitoring locomotion, clean ears and a diet suited to its level of exertion. You must also remain attentive to unusual digestive signs after a meal or intense effort.
Hip dysplasia : A joint malformation that can cause pain, stiffness and locomotor discomfort, especially if the dog gains weight or ages.
Elbow dysplasia : An orthopedic condition that can cause lameness and discomfort, with severity varying depending on the individual.
Hypothyroidism : A hormonal dysfunction that can result in fatigue, weight gain, dull coat or a decline in overall condition.
Ear infections : The ears must be monitored and cleaned regularly to limit moisture, irritation and ear infections.
Gastric torsion : Although not specific to this breed, this digestive emergency requires splitting meals and avoiding intense exertion just before or after eating.
Climate
Cold and heat tolerance
The Harrier tolerates temperate conditions fairly well, but it is not made to endure strong heat or intense cold for long periods. In summer, sporting outings should be shifted to the coolest hours. In winter, extra vigilance is useful during long periods of standing still or harsh spells.
Weight
Tendency to gain weight
As the Harrier is active but readily greedy, monitoring body condition remains important. A ration adjusted to its actual activity, combined with sufficient outings, helps to limit weight gain and joint overload.
Daily life
Good habits to keep it healthy
- Monitor locomotion and consult in case of lameness, stiffness or decreased endurance.
- Examine and clean the ears regularly to limit ear infections.
- Maintain a stable weight to preserve the joints.
- Have regular veterinary follow-up with attention to the hips, elbows and thyroid.
Vaccination
Harrier vaccines: vaccination schedule
Which vaccines for a Harrier? Like all cats, the Harrier receives essential vaccines from 8 weeks old: Typhus (panleukopenia) and Coryza. The kitten primary vaccination for Harrier is given in several injections 4 weeks apart, followed by a first booster at 1 year, even if it lives in an apartment. Depending on its lifestyle (outdoor access, multi-cat household, shows, travel), your veterinarian may complete the protocol with vaccines against Feline leukemia (FeLV), Rabies and Chlamydiosis.
| Vaccine | Primary series | First booster | Then | Who for? |
|---|---|---|---|---|
Typhus (panleukopenia)Core Feline panleukopenia (cat parvovirus) | 8 weeks · 12 weeks · 3 months | 1 year | every year | All pets |
CoryzaCore Feline herpesvirus and calicivirus | 8 weeks · 12 weeks · 3 months | 1 year | every year | All pets |
Feline leukemia (FeLV)Lifestyle-based Feline leukemia virus | 8 weeks · 12 weeks | 1 year | every year | Outdoor cats, cats living in a group or in a cattery |
RabiesLifestyle-based Rabies | 12 weeks | 1 year | every year | Mandatory for travel abroad, cat shows and most boarding kennels |
ChlamydiosisLifestyle-based Chlamydia felis (contagious conjunctivitis) | 8 weeks · 12 weeks | 1 year | every year | Cats living in groups, catteries, show cats |
Adult Harrier vaccine boosters are annual for cat flu and leukemia if it goes outdoors; for panleukopenia, a booster every three years is often sufficient after the first booster. Your veterinarian will adjust the schedule to your cat’s lifestyle.

Adopting well
Adopting a healthy Harrier
Regular veterinary follow-up with particular attention paid to the hips, elbows and thyroid function is relevant in this breed. In the case of sustained sporting activity or a hunting life, a check of the general condition and locomotion is also useful.
