When choosing food for a Cavalier King Charles Spaniel, there are many factors to consider: their age, lifestyle, activity level, physiological condition, and health including potential sickness or sensitivities. Food provides energy to cover a dog’s vital functions, and a complete nutritional formula should contain an adjusted balance of nutrients to avoid any deficiency or excess in their diet, both of which could have adverse effects on the dog.

Clean and fresh water should be available at all times to support your dog’s urinary health. In hot weather and especially when out exercising, bring water along for your dog’s frequent water breaks.

The following recommendations are for healthy animals. If your dog has health problems, please consult your veterinarian who will prescribe an exclusive veterinary diet.

A Cavalier King Charles Spaniel puppy’s requirements, in terms of energy, protein, minerals and vitamins, are much greater than those of an adult dog. They need energy and nutrients to maintain their body, but also to grow and build it. Until they are 10 months old, a Cavalier King Charles Spaniel puppy's immune system develops gradually. A complex of antioxidants - including vitamin E - can help support their natural defences during this time of big changes, discoveries, and new encounters. Their digestive functions are different from an adult Cavalier King Charles’ Spaniel, too: their digestive system is not mature yet so it’s important to provide highly digestible proteins that will be effectively used. Prebiotics such as fructo-oligosaccharides, support digestive health by helping balance the intestinal flora, resulting in good stool.

Similarly, a puppy’s teeth – starting with the milk teeth, or first teeth, then the permanent teeth – are an important factor that needs to be taken into account when choosing the size, form, and hardness of kibble. A formula that contains calcium chelators will help reduce tartar formation. To help support good cardiac function, look for an adjusted mineral content, EPA-DHA, taurine, L-carnitine, and antioxidants in the formula. This intense growth phase also means high energy needs, so the food must have a high energy content (expressed in Kcal/100g of food), while concentrations of all other nutrients will also be higher than normal in a specially formulated growth food. It is recommended to split the daily allowance into three meals a day until they are six months old, then to switch to two meals per day.

The main nutritional goals for adult Cavalier King Charles Spaniels are:

Helping support good cardiac function with an adjusted content of minerals, EP-DHA, taurine, L-carnitine, and antioxidants.

Maintaining an ideal body weight by using highly digestible ingredients and keeping the fat content at a sensible level.

Preserving the health and beauty of the skin and coat with the enriched addition of essential fatty acids (especially EPA-DHA) and borage oil.

At adult age, small breed dogs are exposed to oral and dental disorders, more precisely accumulation of dental plaque and tartar. The Cavalier King Charles Spaniel's teeth and jaws need a lot of protection. A special kibble shape and a texture designed to promote chewing can help in slowing down the formation of dental plaque, and a formula containing calcium chelators will help reduce tartar formation, hence helping to support daily oral hygiene. Small breed dogs are well known for being fussy eaters. Exclusive formula and flavourings, as well as a kibble size with a special texture, will stimulate their appetite. Small breed dogs can be prone to urinary stones; a diet that also helps support a healthy urinary system is recommended to prevent urinary stones.

For Cavalier King Charles Spaniels living mainly indoors, highly digestible proteins, an appropriate fibre content, and very high-quality carbohydrate sources will help reduce faecal smell and volume. Because an indoor lifestyle often means less exercise, an adapted calorie content, which meets the reduced energy needs, and a diet that contains L-carnitine, which promotes fat metabolism, can help maintain an ideal weight. It is important to avoid feeding them human foods or fatty snacks. Instead, reward your dog with kibble taken from their daily meal allowance, and strictly follow the feeding guidelines written on the package in order to prevent excessive weight gain.

After 8 years old, Cavalier King Charles Spaniels start facing the first signs of ageing. A formula enriched with antioxidants will help maintain their vitality and an adapted phosphorus content will support their renal system. Ageing is also accompanied by the modification of digestive capacities and particular nutritional requirements, so food for older Cavalier King Charles should have the following characteristics:

Higher vitamin C and E content. These nutrients have antioxidant properties, helping to protect the body’s cells against the harmful effects of the oxidative stress linked to ageing

An adjusted content of minerals, EPA-DHA, taurine, L-carnitine, and antioxidants to help support good cardiac function

High-quality protein. Contrary to a widely held misconception, lowering the protein content in food brings little benefit in limiting kidney failure because older dogs are less efficient at using dietary protein than younger dogs. Reducing the phosphorus content is a good way of slowing down the gradual deterioration of kidney function

A higher proportion of the trace elements iron, zinc and manganese to maintain good condition of the skin and coat.

A higher quantity of polyunsaturated fatty acids, like borage oil and fish oil, to help maintain the quality of the coat. Dogs normally produce these fatty acids, but ageing can affect this physiological process.

As they age, dogs increasingly suffer from teeth problems. To ensure they continue to eat in sufficient quantities, the shape, size, and hardness of their kibble needs to be tailored to their jaw.
