Should I Get My Dog a Friend? A Dog Trainer’s Honest Take

It’s a question we hear all the time as dog trainers:
“Should I get a second dog to keep my current dog company?”

It’s a sweet thought—and sometimes the answer is yes. But it’s important to make that decision based on more than just emotion or the hope that a new pup will “fix” your current one’s issues.

Let’s take a look at when adding another dog might be a great idea—and when it might cause more stress than companionship.

When Getting a Second Dog Can Be a Good Idea

Your Dog Is Well-Adjusted and Social

If your current dog is confident, friendly, and enjoys the company of other dogs without getting overexcited or overwhelmed, they might truly enjoy a canine companion.

You Have Time, Space, and Resources for Two

Two dogs means double the food, double the vet bills, and often double the training. If you’re ready and able to commit to both dogs equally, it can be a rewarding experience.

You Want Another Dog (Not Just for Your Dog)

It’s important to be honest: do you want another dog? Because even if your current dog benefits, you’ll be the one doing most of the work. If your heart is in it, that’s a great sign.

You’ve Done Proper Introductions

Bringing a new dog into the home should be done slowly and thoughtfully. Neutral ground introductions, trial visits, and matched energy levels are all key for long-term harmony.

When a Second Dog May Not Be the Right Move

You’re Hoping a New Dog Will “Fix” Your Current One

If your dog is anxious, destructive, or reactive, a second dog won’t solve those problems—and could even make them worse. In fact, your current dog may teach the new one those same behaviors. It’s better to address existing issues first.

You’re Not Prepared for the Possibility That They Might Not Get Along

Even with the best intentions and careful planning, sometimes dogs simply aren’t compatible. Differences in energy levels, personalities, or past experiences can lead to tension—or even fights. If that happens, are you prepared to:

• Keep the dogs separated long-term?

• Train and manage both dogs safely with structure and boundaries?

• Rehome the new dog ethically and responsibly if it’s not working out?

This isn’t to scare you—but it’s important to go into this decision with a plan for the worst-case scenario, not just the ideal outcome. Hoping they'll “work it out eventually” often leads to stress and even injury. Responsible pet ownership means being ready to advocate for both dogs, even if it’s not the outcome you hoped for.

Your Dog Is Aggressive or Uncomfortable Around Other Dogs

A second dog isn’t likely to “teach them to be social.” Forcing an antisocial or fearful dog to live with another dog can create constant stress for both animals.

You’re Short on Time or Energy

Training, walking, feeding, and playing with two dogs takes more time than people expect. Puppies especially need separate training and supervision. If your schedule is already packed, it might be worth waiting.

You’re Not Ready for the Transition Period

Even two friendly dogs will need time to adjust. Expect temporary tension, regression in housetraining or behavior, and a need to supervise more closely than usual for the first few weeks or even months.

A Trainer’s Insight: More Dogs ≠ Less Work

Some people think getting a second dog will give their current dog a playmate to burn off energy or keep them company while home alone. While that can happen, dogs aren’t babysitters. In many cases, two under-stimulated dogs will get into twice the trouble!

Dogs need structure, boundaries, and individual attention—even when they’re part of a pack.

Questions to Ask Yourself Before Adding a Second Dog:

• Is my current dog friendly and stable around other dogs?

• Do I have time to train and care for two dogs—individually and together?

• Am I financially prepared for twice the food, vet care, and emergencies?

• Do I want another dog for me, not just for my current dog?

• Have I researched breeds, energy levels, and temperaments that would complement my current dog?

If you answered “yes” to most of these, you’re probably in a good position to start exploring!

Final Thoughts

Getting your dog a “friend” can be a wonderful thing—but only if it’s the right fit for your dog, your home, and your lifestyle. The goal is to enhance the life of both dogs, not stress them out or stretch yourself thin.

Take your time, do your research, and don’t be afraid to consult a professional trainer or behaviorist before making the leap. A thoughtful decision now can mean a lifetime of harmony later.
