Are you a single-dog household but you’re thinking you might want to get a second dog?
We are!
Here are five questions you should consider before adopting a second dog. I’ll include our answers under each tip, in case it’s helpful to see a real-life example.

So, let’s dig in:
If you’re thinking about getting a second dog, whether you’re just in the early dreaming phase or if you’re actively searching for another pup, here are 5 things to consider:
1. How do you know if you should get a second dog?
This is the million-dollar question. How do you know if getting a second dog is the right call or not? Well, the truth is, you don’t.
However, you can make an informed assessment. Ask yourself the following:
- Does my dog enjoy playing with and being around other dogs?
- Can our family’s budget make room for a second set of veterinary appointments, vaccinations, dog food, supplies, and so on? (Check out this post for budgeting tips.)
- Is everyone in my family on board?
- Do I have the time to walk, train, groom, etc. a second dog?
- Is there enough time and space in your home for two crates or for each dog to have his or her own separate rest time? And 1:1 time with you? And supervised play time?
For us, our assessment was pretty simple: Penny loves other dogs. She wants to skitter with every dog she sees and tries desperately to befriend every dog who stops to sniff.
Our whole family is on board because she constantly solicits play from the cats and from the human girls, who are all kinda tired of that behavior, so having a second dog will diffuse some of her playful energy.
And our schedules are extremely conducive to a second dog: Either John or I or we both work from home every day, so there’s an adult here at nearly all times.
2. When should you adopt a second dog?
Timing matters.
If your dog is elderly or suffering from a health condition, it’s probably not the right time to adopt another dog.
If your puppy isn’t fully house trained and your work schedules have changed and the household still needs to adjust or you just had a baby, it’s probably not the right time to add another dog.
Only you will know when the timing is right, but the answers lie within those questions posed under the first point. Everyone, other pets included, need to be on board with adding a second dog.
For us, Penny only recently overcame some of her bigger fears and apprehensions around the house. While her nervousness ruled, it wasn’t the right time to adopt a second dog even though Penny loves playing with other pups. We needed her to be fully settled and secure, plus pretty well-trained on basic cues, before we could even consider another dog. Now, Penny is those things and more!
3. Are dogs happier with a second dog?
This is SUCH an important question and also a tough one to answer directly. Why? Because all dogs are individuals.
Our beloved Cooper, who we lost in 2023, was happiest being an only dog. He didn’t love other dogs in general, and he had no interest in playing with other dogs. He just wanted his people. If we adopted a second dog during the latter half of his life, he might’ve settled into it or accepted the situation, but I’m convinced he would not have been happier than if he were a singleton.
Penny is the opposite. She can’t seem to get enough of meeting new dogs.
Think about your dog and your dog’s specific personality. Does he or she enjoy meeting new dogs on walks? Does your pup seek out opportunities to play with other dogs? That doesn’t necessarily mean your dog can’t or won’t be happier with a second dog, but it’s worth considering.
A lot rests on the personality of the second dog, too. Years ago, when we added a third dog to our original herd, I wrote about some of my multiple-dog-household failings. You can read that here.
4. What are the cons of getting a second dog?
You’ll double your pet care costs, of course.
And you’ll increase the amount of time you need each day for routine pet care, like feeding, walking, nail trimming, and–most especially–training.
Your dogs might need a lot of oversight and management before they bond–and they might not ever bond.
If the second dog is a puppy, well, you get the nightmare of dealing with a puppy.
In our house, the biggest “con” is our cats. Newt and Ripley deserve a say in how things are run around here. Newt does an amazing job setting boundaries with dogs, but she’s spent her entire life with a whole range of dogs with differing personalities. Ripley had only ever been with Cooper, who was a very cat-friendly dog. It took her a good 10 months to accept Penny as part of our little herd, so a huge con for us is the upheaval for Ripley. (Although she’ll likely appreciate another dog playing with Penny instead of Penny trying to play with her all the time!)
5. Am I ready for a second dog?
This is an often-overlooked question.
How do YOU feel about adopting a second dog? Are you ready?
This is a hard one for me because Penny is literally my perfect angel. (She is neither perfect nor an angel, but she is MY perfect angel.) Some of my worries: What if she and a new dog get into a fight and she loses some of the trust we’ve worked so hard to build with her? What if the new dog needs so much attention or training that Penny feels sad or left out? What if Penny bonds more with new dog and stops cuddling me every evening because that is my favorite time of day and I would be so sad to lose that? And so on, and so forth.
Honestly? This is arguably the question you should spend the most time on because, as the human, all of the burden of integrating multiple dogs will fall on your shoulders, and while your existing dog will be significantly impacted–it won’t be any more than you are.
How does your heart feel about adopting another dog?
You’ve decided to bring home a second dog. Congrats! Don’t forget the 3-3-3 rule.
You can read the entire post here, but the gist:
The first 3 days are for your dog to acclimate to his or her new surroundings. This is the “where the heck am I” and “am I staying here” phase. At this point, your dog isn’t showing his or her true colors because of the overwhelm.
The first 3 weeks are for your dog to learn the household rules and boundaries in a loving, kind, positive way. It starts your bonding process off on the right foot (er, paw?) and establishes the foundation of your relationship.
The first 3 months are for socialization, training, and new experiences. By the end of three months, your dog should feel settled and secure. A part of the family.
Only, instead of granting this grace to only the new dog, you need to extend it to include your existing dog, too. He or she will be going through a major adjustment, as well, so allowing lots of time and space for both dogs to acclimate while you remain calm, present, and patient is THE KEY to success.
How do you choose the right second pup for your family?
Where to look? How old should the dog be? Does breed matter? Or gender?
Stay tuned. That’s the topic for next week!

Hoo-boy. Thank you for this and for the next post, which we eagerly anticipate. We’re in the throes of this decision with Rowan, and your perspective is very helpful – both the questions you pose and the answers that are right for you. We go back and forth, and in some ways are just waiting for serendipity to step in and solve it for us.
Waiting for serendipity is an absolutely perfect way to handle it. We’ve ended up with many animals that way! (:
Keep me posted on how it goes for you and your family! We actually have a meet-and-greet with a puppy this coming weekend, so who knows… this might all happen quicker than I anticipated!
We went back and forth on this question for months before we decided to go for it and get a goldendoodle puppy. It was the best decision ever. Our first dog, Maggie, has thrived on having a new puppy to play with. We got the sweetest girl, Mazie, from Southern Sunset Poodles and Doodles (www.scdoodles.com). They were the best to work with and we would definitely do it again.
I’m so, so glad it’s worked out so beautifully!
So much great info here, but I have to admit, I got a little sad to realize Ripley never met Emmit.
Gosh, I know. He would’ve been the perfect first dog for her.
I have been pondering this question for the past 2 months! Would like to foster/adopt another dog, especially when our shelters are full. Still don’t know how my current dog will react. She loves to play with other dogs but because of her size they tend to shy away from her, both dogs and owners. She is a large female am staff/pitbull with a gigantic head.
I am looking for dogs that are described as great with other dogs. But again, still undecided
It’s so hard to know when it’s right. I wonder if your local shelter or rescue might have a foster-to-adopt program where you can try out a pup and see if it works before you commit?
This is so timely! We would like another, but we want to make the right choice for our dog. Thank you for this great advice!
I’m so glad it was helpful! I’m sure you’ll find the perfect pup when the time is right!
This is a long description of one man’s dilemma (me), and his desire for a win, win, win solution.
My wife and I have had five dogs (all pomeranians) since 1990. We have had two poms at the same time since 2012. Fast forward to March 2025. We lost our precious Keisha to heart failure. It broke our hearts. But life must go on. Without allowing ourselves to complete the grieving process, a month after losing Keisha, I agreed to adding a second pom to our family (i.e., me, my wife and our 6-year old pom, Evie). On April 22, 2025, we rescued a 2-year old pom/chihuahua mix. Cute, full of energy, and loving to everyone and anyone. But Sara wants nothing to do with our 6-year old pom. Sara has no boundaries. She runs, jumps, cries when we leave the house, and she is not potty trained. She was in foster care after being abused and used by a animal horder to breed and generate more pups (income?). My wife doesn’t seen Sara’s behavior as a problem and she fell in love with her as soon as we got home (possibly before we got home. LOL). Unfortunately for me, I have always been the leader of the pack. I love them too. But as pack leader, I play with them, walk them, feed them, bathe them, brush their hair (poms require regular brushing), vacuum the house, take them outside to potty, pickup after potty time and cleanup the yard or inside if they mess in the house, Iwash their feet after being outside, take them to the vet, administer medication, even brush their teeth every night. And yes, I (gladly) pay for their care too. I didn’t mention that I do the majority of house keeping inside and outside. So, instead of getting an older pom (5 to 7 years old) we agreed to open our home and rescued Sara from her hell of a life. Now my life is a living nightmare. My wife sleeps with Sara on a sofa downstairs, while I take Evie to bed upstairs. A more concerning issue is that I’m 68 years old and Sara is 2 years old. It’s simple math. Dogs, especially small breeds (and based on our 25 years of experience) can live well into their mid to late teens (one of ours lived 17+ years). So my 70s and, possibly, my 80s, is going to be spent with dog chores. I’m in a dilemma of my own making. I don’t want an untrained “puppy,” nor do I like the chihuahua behavior of Sara’s mixed breed. I won’t allow myself to fall in love with a dog if all I can see is more work than reward. Yesterday, while walking Sara, I met a man mowing/edging the neighbor’s lawn. Sara greeted him with her usual “I love everyone” approach. It was cute. I told him that she is a hand full. Still, he mentioned that his family would enjoy having a dog like her. I would never (ever) place Sara into a foster situation. But this has me thinking about this as a win, win, but lose situation. Sara gets a new loving home (win), I’m able to move forward with life on reasonable terms (win), and my wife…(lose). Back to another dilemma…after an immediate encounter, my wife has fallen in love with Sara. Is this real love, or possibly sympathy or rebound love brought about by grieving after losing our dog Keisha (Keisha was bonded to my wife)? DOES ANYONE have any thoughts or suggestions to my dilemma, or do I need to man-up and accept this as my fate? Thanks.
I’m so sorry for the loss of Keisha. Everyone grieves so differently. From this short comment, I’m wondering if your wife just needed another pup to heal her heart while you needed time to heal yours. We had a similar situation in our house after Cooper died–my husband was not ready for another dog, but my daughter really needed one. These aren’t easy decisions. It also maybe sounds like it’s not Sara–it’s that you don’t want ANY dog at this time in your life?
I don’t have any suggestions, although I’m wondering if your wife took on some of the dog care chores you listed, you might feel a bit better about the pup. Less burdened, anyway. Sending you so much compassion for a difficult situation. Please come back and let us know how it’s going.
