Dog Breeds that Start with O

Unfortunately, dog breed names that start with O are uncommon, especially purebreds.

In fact, there are only two of them that are officially registered in major kennel clubs like the American Kennel Club.

These two dog breeds that start with O are Old English Sheepdog and Otterhound.

Let’s get to know these wonderful dog breeds below.

Old English Sheepdog

The Old English Sheepdog is a medium-sized dog prized for its shaggy white and black fur coat.

Old English Sheepdog is a high-spirited dog breed that’s dedicated to its pastoral duties and devoted to its owner.

These dogs are intelligent creatures that require stimulation from either nature or their training.


The Otterhound is an intelligent hound dog with an exceptional sense of smell and swimming abilities to hunt otters in England.

Like the Old English Sheepdogs, Otterhounds have a shaggy and dense fawn fur coat, and this keeps them waterproof as they swim

Otterhounds can get along with people and their families, but they are known barkers to new faces.

Tips on Making Meaningful Dog Names

Meaningful dog names are important in fostering bonds with your dog. Here’s why.

Dog names should be sentimental, not random.

You want a name that resonates well with your dog’s traits, not a name that’s irrelevant to it.

Its name helps humanize them and treats them like a true member of your household.

So how do you craft a meaningful name for your dearest pet?

Here are five tips to help you create your worthwhile name for them!

1. Get Inspiration from its Physical Traits

Take a look at what makes your dog physically unique.

From their floppy ears and fur coats down to their long muzzle, you can base their name on these dogs’ distinct features alone.

2. Note Your Dog’s Behaviors

Dogs would often showcase noticeable behaviors that you can take into inspiration for dog names.

The behavior doesn’t need to be a quirky one; it just needs to be easily spotted.

In fact, a friend of mine, Zack, named his mixed-breed “Scooter.”

It's because Scooter used to scoot his butt across the floor back when it was a pup.

3. Make its Personality a Reference

Would you name a sturdy and bulky male dog Katie?

Probably not.

Personality itself can be a great inspiration for dog names.

Dog personalities can vary from proud and dominant dogs to people-pleasing canine pals.

An affectionate and adorable pooch deserves a cute-sounding name, while proud dogs can have an aristocratic name.

4. Name It After a Person

Ever noticed that a lot of the dog names in the list are mostly human names too?

That’s right; it’s that easy to name your dogs after human names.

Dog owners would often name their dogs after a person because they have traits that they can easily associate with and relate to their dogs.

That someone could be anything, ranging from families, relatives, celebrities, and even historical figures.

5. Explore and Have Fun

Who says naming dogs is boring?

If you want an enjoyable name to call your dog, then you need to enjoy the process of creating one too!

Inject puns, craft word plays, or experiment with goofy-sounding names.

The possibilities are endless when it comes to naming your dogs, so feel free to explore fun ideas for the dog name.
