Calorie Requirements For Your Cavalier King Charles Spaniel

An adult CKCS at an average weight of between 15 pounds typically requires a diet containing around 500 calories per day. Of course, this requirement can change for a host of different reasons; your veterinarian should be able to tell you when to make adjustments.

A growing puppy, on the other hand, needs larger portions of food in order to develop properly. Puppies weighing about 10 pounds need closer to 1,000 calories per day.

Wet vs Dry Dog Food for Cavalier King Charles Spaniels

Dry Food: If you’ve decided on dry food for your dog, make sure to follow specific feeding requirements for their size and activity level.

Remember, this dog is a toy breed, and typically grows no larger than 13-18 pounds; buy the proper food for your dog’s size. Once you’ve checked that off the list, consulting your veterinarian and checking the bag’s instructions will be your next step. Typically this breed should consume about 1-1.5 cups of dry dog food per day (spread between 2 meals). Of course, every dog is different, so take the necessary steps to ensure feeding the proper amount.

Wet Food: Wet food is beneficial for a number of reasons, and if deemed appropriate for your dog, 1-1.5 cans per day, spread over two meals, is generally appropriate. Of course, consulting your vet is paramount to simply generalizing. It’s also important to read the information on the food can carefully, as many brands differ in serving sizes and nutrient density.

When To Make Adjustments to your Cavaliers Diet

Occasionally, your dog may need their diet adjusted. If your CKCS is putting on or losing a noticeable amount of weight, it might be time to switch foods or change serving sizes.

Ideally, you should be able to feel your dog’s ribs when touching them, but they shouldn’t stick out prominently. They should also have a noticeable and defined waist, but not one that’s too narrow or thin.

If you notice any changes in your dog’s appearance or weight, consult your vet; be sure to discuss nutrition and possible dietary alterations.

Macronutrients and Other Essentials for a Healthy Cavalier King Charles Spaniel diet

Cavalier King Charles Spaniel are prone to a range of health conditions. It is therefore important that they maintain a healthy diet containing a mixture of the below to keep them in the best shape possible;

Protein: This macronutrient is responsible for building and maintaining strong muscles. Especially in growing puppies, protein cannot be overlooked and needs to come from high-quality sources like meat. Vegetable sources of protein do not have the same nutrient profile, and thus might leave your dog’s nutrition lacking. The average size adult Cavalier King Charles Spaniel typically needs about 20% of their diet to come from protein. Run this number by your vet to verify your dog’s needs.

Fat: Another important element in your dog’s diet, fat should also come from high-quality sources – not fillers. This macronutrient helps your dog’s body absorb vitamins and other vital elements that keep them healthy. Of course, fat also has over twice the calories per gram compared to protein or carbohydrates, so make sure to portion correctly. The average size adult CKCS should receive about 5% of their calories from high-quality fat sources. Again, consult with your vet to make sure this is right for your dog.

Carbohydrates: This last macronutrient is another important aspect of your dog’s health, as their bodies use carbohydrates for energy. Carbs should come from vegetables, fruit, or whole grains in their food (think sweet potatoes, apples, or oatmeal) and not filler ingredients like corn meal, corn syrup, or sugar. The remaining percentage of your dog’s diet will come from carbohydrate sources. Check with your vet to confirm.

Fiber: While fiber doesn’t fall into the macronutrient group, it is another vital piece of your dog’s nutrition profile. Fiber is especially important for digestion and absorption of necessary vitamins and minerals. Your dog’s carbohydrate intake should be partially made of up fiber.

Vitamins: Just as humans need vitamins, so does your CKCS. With a well-rounded diet, your dog will receive most or all of its required vitamins already. However (especially when making your own dog food), you may need to add additional supplements to keep them healthy. Vitamins play an important role in your dog’s life by allowing their digestive systems and bodies to function properly. You should discuss your dog’s needs with a veterinarian to make sure they’re not lacking in any area.

Treats and Bones

Dogs have a natural instinct to chew, which is where bones come into play. However, many human companions fail to realize the safety concerns regarding bones, whether manufactured or natural.

One concern involved with giving your Cavalier King a bone is their body’s ability to handle the treat. Contamination or allergies are a real risk, and should not be taken lightly.

More common concerns associated with bones is their ability to break apart into small pieces and end up swallowed whole by your dog. These bone fragments (which are especially easy to detach from natural bones) can end up lodged in your dog’s digestive system, which can require surgery to remove.

While not typically as dangerous as bones splintering, treats should also be chosen and used with care. Generic bone-shaped treats that come in a rainbow of colors should not have a place in your dog’s diet. These bite-sized pieces are packed with filler ingredients that are of no benefit to your CKCS.

Like their food, choose treats that are all natural, with real, single word, ingredients. Another alternative is to make your own treats. For a list of appropriate “human food” to feed your Cavalier King, check out our nutrition guide.

Lastly, never resort to feeding your dog “table scraps” as a treat. Food that is not prepared specifically for your dog should never be eaten by him or her. The salt, seasonings, and oils that go into the food we make for ourselves can wreak havoc on your Cavalier King Charles Spaniel’s digestive system. Always be careful not to reward or accidentally give your dog scraps.
