Every dog has its own personality and quirks, and the Cavalier King Charles spaniel is no exception.

While some owners may find their dog to be the perfect size, others might be surprised at how big their cavalier can get.

So why is my Cavalier King Charles spaniel so big? Let’s take a closer look.

One of the main reasons for the large size of many Cavalier King Charles spaniels is a lack of exercise combined with excessive eating which results in weight gain. There can also be genetic reasons why your Cavalier is larger than others.

Why are some Cavaliers bigger than others

When you think of a Cavalier King Charles Spaniel, the first thing that comes to mind is usually its small size.

But what many people don’t know is that Cavaliers can actually get quite large – some as big as 30 pounds.

If your Cavalier has been putting on some extra weight lately, here are a few reasons why.

One possibility is that your dog may be getting too much food. Cavaliers are prone to overeating and will quickly put on the pounds if they’re not kept in check.

Make sure you’re only feeding your dog the recommended amount of food, and try to avoid giving them scraps or leftovers.

Another possibility is that your Cavalier is not getting enough exercise. Like humans, dogs need regular exercise to maintain their health and stay in shape.

If your Cavalier isn’t getting enough activity, he may be turning to food for entertainment instead.

Try taking him for a walk or playing with him in the yard every day to help burn off some excess calories.

A third possibility is that there may be something wrong with your dog’s metabolism. Some Cavaliers simply have faster metabolisms than others.

This means they require more calories to maintain their weight.

If you’re concerned about your dog’s weight gain, it’s best to consult with your veterinarian to see if there may be an underlying medical issue at play.

If you’re interested in owning one of these big dogs, be prepared for a bit more exercise and feeding than you would need with a standard Cavalier.

Cavaliers come in different sizes

While all Cavaliers are small dogs, there is some variation in size among individual dogs.

Some Cavaliers may only weigh 10 pounds while others may tip the scales at 30 pounds.

This variation is due to a number of factors, including the dog’s diet, exercise routine, metabolism and the breeding profile that has been adopted for this particular example of Cavaliers.
