Longevity
Life expectancy
Its life expectancy is generally around 10 to 12 years. A well-adjusted diet, maintaining a stable weight, regular hygiene care and preventive veterinary follow-up help preserve its quality of life.
Build
A robust breed?
Despite its sturdy appearance, the King Charles Spaniel is not considered a particularly robust breed. Its small size does not protect it from ocular, ear, respiratory and cardiac predispositions that require real day-to-day vigilance.
Watch points
What to watch for
Preventive monitoring must focus primarily on the eyes, ears, breathing and cardiac function. Choosing a rigorous breeding program, observing early symptoms and regular check-ups are essential to limit the impact of the breed’s frequent problems.
Microphthalmia : An abnormally reduced size of the eyeball may be observed and can be associated with other visual impairments such as cataracts.
Cataract : Clouding of the lens can progressively impair vision and requires appropriate ophthalmological follow-up.
Otitis and ear irritations : Its long, fringed ears promote moisture and require regular checks to prevent inflammation.
Respiratory disorders : Its short muzzle can promote less easy breathing, especially in hot weather or in cases of overweight.
Cardiac conditions : Regular cardiac monitoring is recommended due to a known sensitivity of the breed in this regard.
Climate
Cold and heat tolerance
Like many small dogs with a short muzzle, the King Charles Spaniel does not tolerate intense heat and exertion in hot weather well. Its small size also requires protecting it from damp cold and prolonged drafts.
Weight
Tendency to gain weight
This breed tends to gain weight if portions are too generous or activity is insufficient. Strict portion control, limited treats and regular weigh-ins are useful to prevent overweight, which notably worsens respiratory and cardiac difficulties.
Daily life
Good habits to keep it healthy
- Clean and check the ears regularly to limit irritation and ear infections.
- Monitor the eyes and consult promptly in case of redness, tearing, or visual discomfort.
- Avoid intense exertion in high heat and maintain a strict healthy weight.
- Plan regular cardiac and general follow-up with the veterinarian.
Vaccination
King Charles Spaniel vaccines: vaccination schedule
Which vaccines for a King Charles Spaniel? Like all cats, the King Charles Spaniel receives essential vaccines from 8 weeks old: Typhus (panleukopenia) and Coryza. The kitten primary vaccination for King Charles 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 King Charles 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.
