Longevity
Life expectancy
The life expectancy of the Sussex-Spaniel is most often in a good average for a dog of this size. Regular lifestyle hygiene, a stable weight, suitable exercise and attentive veterinary follow-up help to preserve its longevity.
Build
A robust breed?
Without being a fragile dog, the Sussex-Spaniel is not the most hardy breed either from an orthopedic and cardiac standpoint. Its robustness depends greatly on the quality of the selection, the monitoring of bloodlines, and the maintenance of proper physical condition.
Watch points
What to watch for
Particular attention must be paid to the eyes, joints and cardiovascular system. Choosing a reputable breeder, monitoring growth and regular veterinary follow-up are essential to detect potential problems early.
Ectropion : a malposition of the eyelid that can promote irritation, tearing, and eye infections.
Hip dysplasia : a developmental abnormality of the hip joint that can lead to pain, lameness, and osteoarthritis.
Patent ductus arteriosus : a congenital heart defect that requires early diagnosis and management.
Pulmonary stenosis : a narrowing of the pulmonary outflow tract that can tire the heart and reduce exercise tolerance.
Climate
Cold and heat tolerance
Thanks to its dense undercoat and protective coat, the Sussex Spaniel tolerates cold and humidity rather well. It also copes correctly with moderate heat, but like any active hunting dog, it must avoid intense exertion during the hottest hours.
Weight
Tendency to gain weight
Weight management is important in this breed, even if its tendency to become overweight is not marked in the reference data. Its compact build can mask a gradual weight gain, hence the value of regular weigh-ins, a measured ration and sufficient daily activity.
Daily life
Good habits to keep it healthy
- Monitor the eyes and consult promptly in case of redness or unusual tearing.
- Maintain regular activity to preserve the joints and musculature.
- Have the heart checked in case of a murmur, abnormal fatigue or exercise intolerance.
- Choose a breeder who seriously documents the health monitoring of their breeding dogs.
Vaccination
Sussex Spaniel vaccines: vaccination schedule
Which vaccines for a Sussex Spaniel? Like all cats, the Sussex Spaniel receives essential vaccines from 8 weeks old: Typhus (panleukopenia) and Coryza. The kitten primary vaccination for Sussex Spaniel 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 Sussex Spaniel 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.
