So, how much should to feed a Cavalier puppy exactly?

If you have a 1 month Cavalier King Charles Spaniel, he’s likely around a half of a pound, so you’re going to want to feed my about 30 calories (that includes treats) every day that month.

Typically speaking, a good pounds to calorie ratio would be 1:58. So, for every 1 pound they weigh, you’re going to want to feed them 58 calories.

For an example, if your puppy weighs 5 pounds, you’re going to want to feed him approximately 183 calories. If your puppy weighs 10 pounds, you’re going to want to feed them 580 calories.

I recommend that you weigh your puppy yourself so you know exactly how much to feed them. But, before you do that, you can look at this table to get a good idea of what to expect.

Factors That Change How Much They Eat

Okay, we now know that for every 1 pound, a Cavalier should eat about 58 calories a day, but this can change depending on some factors like the sex and age of your dog, the activity of your dog, and whether or not your dog has been spayed or neutered.

Let’s look at each one.

Your Dog’s Sex

The first factor that can change how much your dog should eat is the sex.

Typically speaking, females are smaller than males, thus they will need less food than the males.

Your Dog’s Age

The age, as I mentioned before, plays a very important role into figuring out how much to feed your Cavalier.

As you saw, the older the puppy, the more food they need. Their growth levels off after about a year and a half, however, so they won’t need to keep eating more food.

They will need a better diet when they become seniors. though. Why? Just like when we get old, senior dogs often get health conditions like arthritis which affects the bones. Because of this, they will need a better diet that will meet their needs.

If Your Dog Has Been Spayed or Neutered

Another factor that comes to play when you’re trying to determine how much you should feed your Cavalier is whether or not they have been spayed or neutered.

Dogs that have not been will generally have more muscle and tendon mass. If they have been, they will typically lose a lot of it as an result as the reproductive hormones have been reduced.

Your Dog’s Activity Level

The last factor we will be talking about in this article is their activity level.

As you probably know already, the more a dog is active, the more nutrition that dog will need.

While Cavaliers aren’t overly active dogs, they are very active, typically speaking. If your dog is very active, make sure you are using a dog food that is high in the nutrients they need like protein, health fats, and vitamins.

You may also want to just feed your Cavalier more in general to give them the proper amount of nutrients.

Best Dog Foods For Adult Cavaliers

Alright, now what’s the best dog food for adult Cavaliers?

Generally speaking, good dog food contains the proper amount of protein, healthy fats (i.e. omega 3’s & 6’s), and vitamins (i.e. vitamins A, B, C, D, E, & K).

Personally, for your adult Cavalier, I recommend Iams. I actually use this brand for my dogs

Best Dog Food For Senior Cavaliers

Unfortunately, I cannot recommend any product for seniors, but in general, you’re going to want to get a dog food that has the proper nutrients they need like omega-3 fatty acids such as eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) and proteins.

Also, a dog’s brain after around the age of 7, begins to lose it’s ability to produce glucose. and a good way to help with that is supplementing your dog’s diet with medium chain triglyceride oils (aka MCT oils).

Considerations Before Buying Dog Food 

Lastly, before you buy any dog food, take all of these considerations in mind.

The last thing you want to do is end up buying a dog food that is not right for you or your dog. So, what are the considerations?

Does It Contain Enough Nutrients?

Like I said many times in this article, no matter what dog food you buy, always be certain it contains the right amount of nutrients for your dog.

In general, a dog will need healthy fats, proteins, and vitamins A, B, C, D, E, K, and choline.

In general, vitamin A is known as a vitamin that is good for vision and the eyes and is often found in carrots, spinach, and collard greens.

Can I Afford To Buy This Dog Food When I Need It? 

The next consideration you must make is if you can actually afford the dog food you buy.

The fact is, dog food can get really expensive, especially if you buy dog food that is actually healthy for your dog.

Make sure that you can actually afford the dog food you buy. The last thing you want to do is buy dog food that you won’t be able to afford when you need it and have to get a dog food that is of lower-quality.

Will My Cavalier King Charles Spaniel Eat It? 

Finally, the last main consideration you have to make is whether or not your Cavalier will actually eat it.

While not all dogs are picky, I know that my dogs are very picky and I’m sure there are picky dogs in every breed.

They should eat the dog food you buy if they get hungry enough, however. You may just have to wait for them to get hungry and then they should eat it.


So, how much should you feed your Cavalier? Well it depends on a lot of factors like age, sex, the activity level of your dog, and whether or not it has been spayed or neutered.

Do you have a Cavalier? If so, how much food do you give it every day?
