Cavalier King Charles Spaniel feeding notes

Cavaliers (5.9–8.2 kg) are easy keepers that gain weight quietly β€” a 7 kg neutered adult needs only about 480 kcal a day (RER = 70 Γ— 7^0.75 = 301, Γ— 1.6), so measured meals beat eyeballed bowls. The breed's defining disease is mitral valve disease, which affects more than half of Cavaliers over age 5, and extra weight makes an already-stressed heart work harder: keep ribs easily palpable (body condition score 4–5/9) and keep up the annual β€” later twice-yearly β€” cardiac checkups your vet recommends.

Frequently asked questions

How much should a Cavalier King Charles Spaniel eat per day?

A typical 7 kg neutered adult Cavalier needs about 480 kcal per day (RER = 70 Γ— 7^0.75 = 301, Γ— 1.6) β€” about 1ΒΌ cups of a typical 400 kcal/cup dry food, split into two meals. Cavaliers are quietly food-motivated, so calculate from your dog's actual lean weight and re-weigh monthly rather than following the bag chart.

How much should a Cavalier King Charles Spaniel weigh?

The Kennel Club/AKC breed standard gives 13–18 lb (5.9–8.2 kg) for both sexes, making it a small breed. You should feel the ribs with light finger pressure and see a waist from above β€” body condition score 4–5/9. If your Cavalier runs heavy, the standard first step is a 10% food cut and a re-weigh two weeks later.

Why does weight matter so much for a Cavalier's heart?

Mitral valve disease (MVD) is the breed's leading health problem β€” UK health surveys report it affects more than half of Cavaliers over age 5, and it was the most common single cause of insurance claims for the breed in UK data (about 20.5%). No diet prevents MVD, but obesity adds cardiac workload: keep your dog lean, skip salty table scraps, and let your vet stage the disease with regular auscultation so medication can start on time.

How much should a Cavalier puppy eat?

Feed 3 measured meals a day until 6 months. A 3-month-old (around 3.5 kg) needs roughly 360 kcal per day β€” about twice the resting energy requirement (RER 179 Γ— 2) β€” from a small-breed puppy formula. Weigh every 2 weeks and adjust portions to keep the puppy lean rather than pushing growth.

When should I switch my Cavalier to adult food?

Around 10–12 months. Cavaliers are a small breed that completes most growth by 9–10 months, and calorie-dense puppy food past that point feeds the breed's signature weight creep. Transition over 7–10 days, then recalculate portions from the adult food's calorie density β€” and keep lean-feeding habits for life: in the Purina LifeSpan Study (Kealy et al., 2002), lean-fed dogs lived a median 1.8 years longer.
