5 Best Companion Dogs for Cavalier King Charles Spaniel

If you ask me, when it comes to dogs, the more, the merrier! Our furry fellows bring so much joy everywhere they go, so it’s easy to see why many dog owners want to keep more than one. Not only are they bright and shining stars in human lives, but they can also be great company for each other.

However, finding the perfect match to join your pet can be a bit difficult. Some breeds may be a bit territorial, while others may be too anxious. In this article, I’ll cover the best companion dogs for Cavalier King Charles Spaniels!

Are Cavalier King Charles Spaniels Good With Other Dogs?

Overall, Cavalier King Charles Spaniels are great with other pets. If you’re wondering whether your Cavvy would get along well with other dogs, you can rest assured that the answer is yes. Cavvies are very patient and dependent dogs, and they love company.

Cavalier King Charles Spaniels are known to be calm, friendly, and, most importantly – adaptable. Consequently, they quickly get used to new lifestyles. 

Combine that with their codependent tendencies, and you’ll quickly learn that your pooch would love to have a new friend around! 

Cavaliers are known to suffer from separation anxiety, which owners may find difficult to deal with. However, that makes them a perfect family dog and a good candidate for companionship. Your Cavvy will never be lonely again with another pup in the house!

Do Cavaliers Get Along With Big Dogs?

Yes, Cavalier King Charles Spaniels get along with big dogs as well. As mentioned, they are friendly, loving, and docile and tend to do well with most breeds – even with those much larger than themselves. 

However, it’s important to consider your pet’s personality if you wish to bring in a big dog. Namely, some Cavaliers may be intimidated by bigger dogs, which could cause more anxiety issues.

On top of that, let’s not forget that Cavaliers are somewhat fragile and only weigh between 13 and 18 lbs. A larger, high-energy dog may accidentally hurt your pooch during playtime.

Let’s see which dog breeds get along best with Cavalier King Charles Spaniels and why! 

Boston Terriers

Much like our Cavvies, Boston Terriers are amazing family dogs and are very attached to their owners. As such, they are the perfect companion for your puppy.

They can keep each other company while you’re away, provided both of them get a lot of pets when you get back!

The Boston Terrier is a surprisingly low-maintenance dog that can thrive even in small apartments as long as you provide a lot of affection and love. 

Like Cavaliers, these dogs have a high prey drive, so make sure you don’t have any small pets if you choose to go with the adorable Boston Terrier.

Did you know that Papillons are also called Continental Toy Spaniels? The adorable, small dogs, famous for their “butterfly” ears, are also Spaniels, and they get along well with Cavvies. 

Papillons are even smaller, making them an ideal addition to your family. 

If you opt for this charming breed, ensure the dog is socialized correctly from the beginning. The Papillon is friendly and loving but may be a bit timid around other dogs if not properly socialized. 

Similarly to King Charles Spaniels, these dogs are prone to separation anxiety and would love to have company all the time.

French Bulldogs

Perhaps you noticed a pattern in our list. Finding breeds with comparable personalities is typically your best bet when it comes to dogs that live together.

Continuing with the trend, we have the popular French Bulldog, an affectionate, caring dog who hates being alone. The French Bulldog could be the perfect companion for your Cavalier. 

Frenchies easily adapt to apartment living. They aren’t high-energy and would rather curl up on the couch with their owner. They make the perfect family dog and might become your Cavalier’s new best pal.

Next up on our list is the controversial Pug. Pugs are a unique and lovely breed, though some people mind their appearance. 

Nevertheless, if you’re a fan of this small dog, rest assured that it will get along nicely with Cavalier King Charles Spaniels. 

Caring, loving, loyal, and affectionate, they make great family dogs. Also, Pugs, like Cavaliers, are ideal for apartment living due to their medium energy levels and need for regular walks. 

They are playful and very attached to their owners, and they don’t enjoy spending time alone, making them the perfect friend. 

If you’re looking at pugs as your Cavvy’s new companions, you’re in the clear!

Shih Tzus

Last but not least, getting a Shih Tzu can be a great fit for your Cavalier. However, unlike Cavalier Spaniels, Shih Tzus are slightly more independent and tolerate being alone. 

Still, that doesn’t make them emotionless dogs, far from it. Shih Tzus are extremely affectionate and kind and get along well with kids and other pets.

With low energy and low exercise needs, the Shih Tzu is a perfect lap dog. If you’re looking for a companion dog for a Cavalier King Charles Spaniel, the adorable Shih Tzu might be a good fit. 

Just remember to say goodbye to your personal space – you’re not going to have any once you adopt another furry friend.
