Can you change a dog's name?

For some pet parents, naming a dog can be as simple as choosing between “Bella” and “Daisy” and calling it a day. For others, it can be difficult - they’re our tailmates after all, and we want to choose a name that fits. Things can get even more challenging when your pup enters your life with an existing name assigned by a previous pet parent, breeder, or shelter.

What if the name doesn’t fit? And on the flip side, what if changing their name creates unanticipated problems? Can you change the name of a dog, or is it not worth it? Well, we wanted to find out the facts: we used consumer research platform Attest to survey more than 1,000 pet parents who adopted a dog with an existing name.

This data allowed us to explore their motivations for changing their doggos’ names (or keeping them the same), the creative inspirations they drew upon when picking a new name and how dogs adapted to this change.

Here, we discuss how to rename your dog and share some interesting data on how pet parents like you found the experience.

How many people rename their dogs?

Not many adoptive pet parents choose to change their pet’s name. Our data found that only one-third (33%) of dog parents in our survey chose to rename their pups.

This is still a significant percentage, of course. In the long run, dogs are adaptable to name changes. This flexibility opens up opportunities for pet parents to choose names that they feel are a better fit for their pet’s personalities.

Reasons why pet parents change their dogs’ names

There were two reasons that were more common, however:

• 41% said they “just liked the new name better”.

• 35% said the whole family came together to reach a consensus.

• 33% said they did so because they believed a different name would better capture the dog's unique personality or appearance.

Interestingly enough, 7% of pet parents made the change to sever negative associations linked to the previous name. It’s understandable: for many rescued dogs, their names may carry the burden of a troubled past, and a new name may symbolise a break from those hardships and a hopeful step towards a nurturing future.

Ultimately, a dog’s name is more than just a label; it's an acknowledgement of their place in a family and a marker of identity. It’s no surprise that pet parents often choose a name that complements the dog’s persona and their family's values. But sometimes, it’s just about picking a name that sounds adorable.

Where do we get our dog name ideas?

So how do dog parents decide on a new name for their canine companions?

As it turns out, the sources of inspiration can be pretty diverse. 50% of dog parents said they simply liked the sound of the new name. It’s not surprising: pet parents use their dogs’ names in everything from commands to praise, so it's important to choose a name that’s enjoyable to say (and hear).

Meanwhile, 35% cited their dog’s characteristics or personality as their biggest inspiration. (“Princess” was a top choice). Other sources of inspiration included book/movie/TV characters (18%), family/personal namesakes (13%), and even historical figures (9%).

Regardless of inspiration, changing a dog's name isn't without its complexities. Choosing a name based on a favourite character or good old-fashioned auditory appeal may provide a fresh start, but it also initiates a transition period for pets and their parents.

How dogs adapt to new names

If you were suddenly forced to change your name, you might be in for a challenging adjustment. But our canine companions boast astonishing degrees of cognitive flexibility. Of all the name-changed canines in our survey, 73% were able to adjust to their new names in just a few days.

This rapid adaptation highlights a dog's innate ability to form new associations quickly, a skill that helps them fit into new environments and bond with their new families rapidly. However, not all dogs adjust at the same pace.

About 18% took a more gradual approach, slowly coming to recognise their new names over several weeks. A further 3% needed several months, and another 3% were still struggling to make the adjustment, according to respondents.

This period of adaptation often involves a deliberate process of reinforcement from the new owners, who may use treats, praise, and affection to positively reinforce the dog’s response to the new name. Factors like a dog's age, past experiences, and training methods can influence how quickly and effectively the dog responds to the change.

How the 3-3-3 rule applies

You may have heard of the 3-3-3 rule in dogs. It’s a guideline for how and when adopted dogs settle in. The rule states that pet parents should expect:

• Three days to decompress

• Three weeks to learn a routine

• Three months to feel fully at home

So, how does this apply to renaming? Well, it shows just how long it takes for dogs to settle in with something new, so be patient. Don’t expect overnight results, and imagine if you had your name changed: it’d take you a while to get up to speed!

Strategies for successful dog name changes

Renaming a dog isn’t always easy. Your dog can benefit greatly from a strategic and empathetic approach. Dog parents need to use the new name consistently during positive interactions to help forge strong new associations.

You should call them by their new name during enjoyable activities such as feeding, playing, enrichment, or other affectionate moments. This helps build a strong, positive connection with the name, as well as quicker recognition.

Remember, positive reinforcement is a cornerstone of any effective name-change strategy. Rewarding your dog with treats, praise, or affection when they respond to their new name helps lock in their good behaviour.

For newly adopted dogs or those without strong attachments to their old names, making a complete and immediate switch to the new name can be effective. Consistently using the new name and reinforcing it with positive interactions, like treats and praise, can help the dog quickly associate the name with themselves, making for a smoother transition.

But if your dog shows a strong attachment to their old name or seems confused by a sudden change, consider a gradual transition. You might start by using both names interchangeably, or even together as a combined phrase —think “Buddy-Spike.” Then you can gradually increase the use of the new name while phasing out the old. This method can help ease your dog's stress and anxiety, which could lead to a gentler adjustment period.

Step-by-step: how to teach your dog a new name

The process of teaching a dog a new name can be a delicate one, especially if the dog has already responded to a previous name for years.

Here’s a quick step-by-step guide:

• “Train” the new name in quiet, calm spaces - Training in quieter, calmer spaces is better for dogs.

• Use positive reinforcement - Positive reinforcement training is always the way to go, so make sure you reward your dog when they respond to their new name with a treat or some praise.

• Don’t use their name too much if they ignore you - Your dog won’t respond to their new name, so it’s something you’ll need to build up over time. Try to get more animated when using their new name, but don’t use it so much that they become anxious or confused.

• Be consistent - Things can take a while to change, so be patient and consistent. Don’t rush things, and never express impatience or negativity while your dog adapts to their new name.

What should you do if your dog is struggling with their name change?

Some dogs, particularly those with longstanding attachments to their previous names or those who have had significant experiences associated with them, may continue to respond better to their old names. In such cases, it may be wise to seek professional guidance.

Dog trainers and behaviourists can provide customised advice and techniques tailored to the individual needs of the dog. Their expertise can be invaluable, offering structured approaches and modifications to standard practices that better suit specific situations.

Among survey respondents who said their dogs had been struggling with the adjustment, 36% said they planned to continue working on name recognition training, and another 36% said they planned to consult a behaviourist. A handful of these brave souls—9%, to be exact—said they planned to try yet another new name.

Ultimately, you may simply find that your best bet is to retain your dog’s original name. Of the survey respondents who said they were struggling, 18% said they were thinking of doing just this. And remember, two-thirds of respondents didn’t bother switching in the first place.

Challenges of renaming your dog

Renaming a dog isn't always smooth sailing. Of the survey respondents who were encountering difficulties with the adjustment process, 36% reported that their dogs appeared confused at times, and another 36% said their dogs didn’t always respond to their new names. This confusion can disrupt training routines, basic recall, and everyday socialising, making it difficult for dogs to understand what’s expected of them.

Perhaps more intriguingly, 27% of pet parents observed that their dogs seemed to respond more readily to their previous names. This phenomenon is most common in dogs whose previous names were used during significant periods of their lives, such as during early training or while forming initial bonds.

Despite their adaptability, dogs do have strong memories.

Picking the right name: what works best

There are a few key rules when you’re picking out a new name for your dog:

• Choose names that sound clear and crisp, not complex.

• Don’t pick names that sound like common commands.

• Don’t use negative reinforcement, especially with the new name - that doesn’t build positive associations, and you should always use positive reinforcement principles.

• Pick a name that matches your pet’s personality or perhaps their physical characteristics (e.g. Patch, Spot, Tiny, or Red).

• Say the name out loud and see if it fits.

• Try not to use too many syllables.

Reasons why you may not want to change names

Now, we’re not here to tell you what to do or how to be the great pet parent you are. But here are some reasons why you may want to hold off on that name change:

• Confusion: Changing a dog’s well-established name can lead to disorientation for dogs, leading to stress.

• Discomfort: A dog finds their name comforting, especially from their pet parent, so changing it can lead to feelings of instability and discomfort.

• Previous training: A dog with a significant training background, like working dogs, has associated their name with critical commands. Changing it can impact how well they follow commands, train and settle in.

Moving on with a fresh start

If you're considering a name change for your dog, remember that patience and consistency are your best tools. Use the new name positively and frequently, and reward your dog for their responsiveness. For those whose pets continue to struggle, keep in mind that resources like professional trainers are available to help guide you through the process.

Finally, remember that protecting your pet’s health is just as crucial as nurturing their identity. Dog insurance can help you stay prepared for every aspect of your pet's care, no matter what new adventures (or monikers) lie ahead.

Frequently asked questions

Is it cruel to change a rescue dog's name?

It depends on the history behind your rescue. In most cases, you can change their name, especially if they have negative associations with their old one. It’s really important to learn about a rescue dog’s history, as this will impact training, settling in and behaviour.

How long does it take for a dog to learn a new name?

It depends on how old the dog is, how long they’ve had their current name, their training history and how you introduce the new name. Sometimes, it can take as little as three to seven days with consistent, diligent positive reinforcement in younger dogs. But we’d expect it to take a few weeks or even longer; patience and consistency are key here.

Should I keep the shelter's name for my dog?

Again, it depends on the name’s history. If the shelter has given them a new name, then you may want to keep it - there’ll be plenty of other training and settling in to get on with as you introduce them into your home. But you can change it if you like.

What are the best types of names for dog training?

Short, simple names with one or two syllables work best,

What names should I avoid for my dog?

We’d avoid names that sound too similar to common commands, like:

• Joe, which sounds like no

• Kit, which sounds like sit

• Ray, which sounds like stay

Can I change an older dog's name?

You can, but it will be harder. Older pets can still learn and have new experiences, but it won’t be as quick as renaming a puppy, for example.
