If you look around the house and feel like something is missing, perhaps you're wondering, "Should I get a second dog?" Whether the idea just came to you or you've been considering it for a while, chances are that you need some help with the decision-making. After all, bringing another dog home is a big decision that comes with incredible benefits as well as some challenges.

Getting a second dog isn't the right choice for everyone—but it might be for your household. It depends on your lifestyle, current dog, and resources, all of which should be taken into account before welcoming a new pup into your life. This guide covers all of these factors and more to help you determine if it's a good idea to get a second dog.

Getting another dog: pros and cons

There are definite upsides and some potential downsides to adding another dog to your household. Let's review the various outcomes.

Benefits of having two dogs

  • Companionship. Not only can a second dog bring you additional emotional and social support, but they can also provide your first pup with some much-needed companionship. Both dogs will have a built-in pal every day. Plus, doggy companionship may even help your pups' health. A 2023 study from the Dog Aging Project shows that dogs who lived in households with other dogs or pets had higher overall health scores than those who didn't.
  • Play and stimulation. All pups crave (and need) playtime, including both mental stimulation and physical exercise. But some are higher energy or need a lot more exercise than others, such as Siberian Huskies and Labrador Retrievers. Having two dogs can provide the energy outlet that your pups need.
  • Reduced separation anxiety. In some cases, providing your first dog with a companion may help them with separation anxiety issues, but this may only be effective for dogs that crave the companionship and comfort of other pets. If your first pup's separation anxiety is due to your absence, then a second dog's presence might not help. In these situations, it's best to first train your dog in minimizing their separation anxiety.
  • Socialization for a new puppy. Well-trained adult dogs can assist with puppy socialization and help them learn good behaviors. Now, it's important to never rely on your adult dog to "train" the puppy. Instead, your puppy can simply see good behaviors being rewarded or praised and may be more likely to emulate those behaviors.

Challenges of having two dogs

  • Double the costs. Double the dogs means double the costs of pet care, including food, medicine, toys, veterinary care, pet insurance, boarding/pet sitting, and other pet gear. For many pet parents, these extra costs are worth the companionship and joy of having two dogs, but finances are important factors to keep in mind.
  • More time and training commitment. Another challenge can be the time commitment needed to train your new dog, train both dogs together during the adjustment period, and give both pups love, attention, and care for years to come.
  • Potential behavioral conflicts. Personalities, energy needs, and level of socialization and training all affect how well two dogs get along. Adding a new pup to the mix might aggravate any emotional or behavioral issues in your first dog.

Is your current dog a good candidate for a companion?

With these pros and cons in mind, is it a good idea to get a second dog? Part of answering this question is determining whether or not your current dog is ready for a furry companion. Here are some important factors to consider.

Social vs. reactive

"Social" in this instance isn't referring to whether your dog is a little socialite, going up to whomever is nearby in hopes of a pat on the head. Instead, social vs. reactive refers to your dog's level of comfort and calm in various situations.

If your dog is socialized, that means that they are generally comfortable around new sounds, people, and places; other dogs and pets; and potentially anxiety-inducing situations, such as the groomer or a very busy outdoor area. It doesn't necessarily mean that they behave perfectly every time, but generally speaking, a socialized pup has the training and temperament to adapt to and maintain good behavior in these various situations.

A reactive dog, on the other hand, might exhibit unwanted behaviors in situations where they don't feel comfortable or safe. Perhaps they growl when other dogs get close to you, lunge at other dogs while on walks, or show other aggressive behaviors when something triggers them.

If your dog is showing consistent reactive behavior, it's likely best to wait to get a second dog, instead focusing on training your current pup to adapt to triggers, heed basic commands, and stay calm in various situations. Well-socialized dogs are often better candidates for introducing a new pup into the household.

Temperament and personality

What is your dog's overall temperament like? Are they happy-go-lucky, sociable, and easy-going with humans and pets alike? Do they tend to resource guard or be fiercely loyal and protective of you?

Answering these questions will help you decide whether to bring another dog into the mix and give you insights regarding how to know if your dog needs a companion. Some dogs may naturally be more accepting of new furry housemates, while others may not or at least need ample time to adjust to the new addition.

Age and energy level

Your dog's age and energy level should also be factors to consider before introducing a second dog. Some dog breeders recommend waiting until your current dog is at least 2 to 3 years old before introducing a second dog. This way, you won't be dealing with one or two puppies at the same time, and your current dog will have lots of training under their belt.

Some pet parents wonder if having a senior and younger dog together will work. In truth, it depends on the dogs. While having two dogs closer in age to each other will ensure that their physical capabilities are similar for a longer period of time, it doesn't mean that old and young pups won't get along swimmingly. You'll just need to consider your current senior dog's level of stamina, physical abilities, and temperament.

Finally, no matter the age of your current dog and potential dog-to-be, always think about their energy levels. For instance, if your current dog is rambunctious and needs a lot of exercise or mental stimulation, it might be best to get another pup that matches their need for speed.

Signs you’re ready for a second dog

If your own dog is ready for a companion, you still might be wondering, "Should I get a second dog? How do I know when the time is right for me?" Here are some signs that you might be ready for the additional challenge (and joy) of another pet:

  • You're financially stable.
  • You have enough time for training, bonding, and exercising with two dogs.
  • You won't be traveling for long periods of time in the coming months.
  • You have the space at home to accommodate two dogs.
  • The other people in your household are also ready for another pup.

How to introduce a second dog successfully

If you've decided that having two dogs is the best choice for your situation and household, congrats! Before you head to the adoption center or breeder, make sure to read these tips for introducing a second dog.

  1. Get your household space ready. Buy everything you need to accommodate two dogs. That means two water bowls, two food bowls, two dog beds or crates, new toys, and so on. Ideally, these items will be in separate spaces at first. Having these in place ahead of time can help to avoid future conflicts between both pups and ensure that both are comfortable.
  2. Introduce the dogs in a neutral place. A best practice is to avoid introducing your current and new dog at your home or in your yard, as these places are your current dog's safe space. Choose a public park or another calm outdoor area near your home where the dogs can meet.
  3. Keep leashes on during the first meeting. Have a friend or family member (someone that your current dog feels comfortable with) bring your pup to the neutral meeting place, while you bring the new dog. With both dogs on leashes, slowly walk up to each other, letting the pups sniff and interact. You can also try walking both dogs in the same direction, so there is less of a focus on the actual introduction. Praise and reward calm interactions. If they remain calm, you can try slowly loosening their leashes, giving them more space.
  4. At home, let them explore their spaces. Either walk home together or drive each dog separately. If you have an enclosed outdoor space, first let the dogs interact and explore there with loose leashes. When it's time to move indoors, let the new dog enter first and have time to wander and explore on their own. Then, let your current dog inside, with both dogs leashed. Calm interactions, again, should be rewarded.
  5. Always supervise. Don't leave your dogs alone while they're adjusting to each other. Supervise them when you're outdoors and inside so that you can intervene if any altercations occur or if either one starts to show signs of anxiety or aggression.
  6. Keep resources separate. In the beginning, try to keep food and water bowls, toys, and crates separate. This setup can help your current dog have continuity and comfort and let your new dog get used to eating and sleeping in their new space.

Cost of owning two dogs

To further prepare for a second dog, it may be helpful to get a big-picture look at the costs involved. No two dogs are the same, so some may be more expensive than others. But understanding at least the basic costs of owning a pet (or two) will provide the clarity you need to embark on this new journey.

  • Dog food: $600–$2,400/year
  • Prescription medications: $50–$500/year
