Should You Adopt a Second Dog? Vet-Verified Pros, Cons & Considerations

Those who have had a single dog living in their home for a while may, at some point, consider adopting a second dog. Adopting a second dog comes with many pros, such as your current dog having a doggie companion, as well as some cons, like the cost of caring for two dogs. It’s a lot to consider!

Whether or not you should adopt a second dog will depend on how much the pros outweigh the cons for you, so you should have a good idea of what those are before making a decision. Here’s a closer look at everything you should consider before bringing another dog into your home and heart!

The 5 Pros of Adopting a Second Dog

There are several pros to adopting a second dog, both for yourself and your current dog.

1. Added Fun

The obvious benefit to adding a second dog to your home is all the added fun! Having more than one dog in the house means you and your current dog get to have twice as much fun as you used to. As much fun as you’ll have, though, your current dog will be able to have more, as they can play and run around with another pup who can keep up with them (which has the added benefit of helping your canine companions stay healthy).

2. Dogs Feel Secure

Canines are pack animals, so the more of them around, the more secure they can feel (which is not an invitation to go out and adopt a dozen dogs!). Having more than one dog in your home, though, can help reinforce this idea of a pack. Between having your family and each other, your pets will have an added layer of security.

3. Companionship

Companionship is a significant pro to adopting a second dog, especially for your current dog. While you and your family get to reap the benefits of companionship, too, another dog may be even better for your current one. If everyone in the home is out at school or work for most of the day, then your current dog may be lonely and bored at home alone. With another pup in the house, they have another presence to help keep them entertained.

4. Can Improve Health

A 2023 study from the Dog Aging Project looking at social environmental factors affecting health and disease in pet dogs, found that regular social interaction and support, such as living with other dogs, was associated with better health.1

5. Lives Saved

If you’re adopting dogs from a shelter, you have the extra pro of saving lives by providing a good home to dogs in need. And what’s better than that?

The 5 Cons of Adopting a Second Dog

Despite all the pros of adopting a second dog, there are also several cons you need to factor in.

1. Twice the Work

Probably the most obvious con of owning two dogs is that it means you’re doing twice the work. Two canines in the home means picking up more poop, extra grooming, more trips to the vet, ensuring each dog gets enough exercise, and more. It can be a lot, especially if it’s only you who is caring for them. It may also take a second dog time to fit into an already established routine (or they may not fit into it at all, making their own instead), leading to more challenges.

2. Twice the Cost

And don’t forget the extra costs of having a second dog! Two dogs mean you’re purchasing twice the amount of food, supplies, toys, and medications. Plus, all those newly added visits to the vet can add up, and if you need to utilize a boarding facility, it will be twice the cost. Ensure you’re financially prepared to cover all these extra costs before getting another dog.

3. Double the Training

Training goes along with the extra work created by having twice the number of pets, but you should know that training more than one dog can be tricky. There’s no guarantee that your dogs’ temperaments will match up so that they respond equally well to the same training. You may end up having to train your dogs separately. You also want to be sure that if you have a confident dog and a less confident dog on your hands, the confident one isn’t trying to lead the way with the less confident one. Otherwise, you could see behavioral issues down the road.

4. Personality Clashes

Canines have individual personalities, and sometimes, those personalities simply clash. That means there’s no guarantee that your current dog and a new one will get along, and there are times when not even training and socialization will make them friends, which can cause issues in the home. It’s normal for things to be tense when dogs are first introduced to each other, but that tension might not go away.

5. Challenging Travel

Do you travel a lot? Do you usually take your dog along with you? Then, be prepared to have that travel become more of a challenge. Having two dogs on your hands means you need to find places to stay that allow more than one dog to a room, as well as the likelihood of paying more for accommodations. It also means you have to pack up twice the amount of stuff you used to bring on trips. Taking two dogs on trips can prove challenging, so if you have a love of traveling with your pet, consider this.

Other Considerations

There are a few other things you should consider before adopting a second dog.

First, do you really want a second dog, or does someone else in the home want another pup? Adding another pet to your home is a big life decision, so if everyone in your house isn’t on board with it, you probably shouldn’t go through with adopting a second dog. If another member of your family is super excited about another pup, but you’re far less enthused, then the answer probably isn’t getting a dog. It could lead to tension and hurt feelings if you go through with it.

Another consideration is whether you’re bringing in a second dog for yourself or for your current dog. If your current pup is dealing with separation anxiety, it might seem like an excellent idea to add another dog to your home, but in reality, it might not go the way you think. Sometimes, dogs with anxiety can make other dogs more anxious, instead of the calmer dog making the anxious one less so. Or perhaps your current canine companion is reactive or even a bit aggressive. Socializing them with another dog in your home could seem wise, but there’s no guarantee a reactive or aggressive dog will be comfortable with or trust another canine in their space, which could lead to even more issues. Work with your vet or a behaviorist to deal with your current pup’s issues before thinking about a second dog.

Finally, do you have a backup plan if you are going to adopt another dog? As much as we always want things to work out, sometimes they simply don’t, and if a second adoption doesn’t work out for you for some reason, you need to have an idea of what you’ll do. Many shelters allow for a trial period before an adoption goes through, so consider that. If yours doesn’t, think ahead about what you’ll do if you need to rehome a canine.

Final Thoughts

Adopting a second dog is a significant life decision, so you should think long and hard about it. There are plenty of pros to adopting another pup, but you should consider whether they outweigh any cons or vice versa. Also, think about why you want another canine; do you want more companionship, or do you think a second dog will help your first in some way? Essentially, you should consider all the aspects of owning another dog very seriously before committing to adoption.
