What I Wish I Knew Before Getting a Second Dog

Getting a second dog sounds like a dream—twice the love, twice the fun, and a ready-made playmate for your current pup. But in reality, adding another dog to your household can come with a few surprises. While it can absolutely be a rewarding decision, it also brings new challenges that are easy to underestimate.

Here’s what many dog owners wish they knew before bringing home dog number two.

It Changes the Dynamic

Your current dog has their routine, their favourite spots, and their rhythm with you. Adding a second dog shifts that balance. Even if they get along well, it takes time for both dogs to adjust to living together. You might see temporary jealousy, guarding behaviours, or competition for your attention.

You’re not just building a relationship with the new dog—you’re managing the relationship between the two of them. It’s a whole new social setup that needs supervision, patience and sometimes separate space while they figure each other out.

Twice the Love, Twice the Work

Two dogs means double the feeding, walking, training, and cleaning. It’s easy to assume they’ll just entertain each other—and while they might sometimes, they still need one-on-one time with you. Walks can be more complicated if they have different paces, and training often needs to be done separately at first.

Some dogs feed off each other’s energy in great ways—but also in not-so-great ones. One anxious dog can influence the other, and bad habits can spread if you’re not careful.

The Cost Adds Up Quickly

Vet bills, insurance, food, grooming, and boarding—all of it doubles. Even small things like leads, toys and flea treatments add up. Unexpected costs, like emergency care or behavioural support, are also more likely with two dogs.

Before getting a second dog, it’s worth reviewing your budget to be sure you can comfortably afford both dogs’ long-term care, not just the initial adoption or purchase.

Matching Dogs Takes Thought

Not every dog will welcome a new sibling. It helps to match energy levels, ages and personalities. A calm older dog may find a hyper puppy overwhelming, while two dominant dogs might clash. Choosing a dog with a compatible temperament can make the adjustment period much smoother.

Rescues and breeders can often offer advice on the best match for your current dog—so it’s worth involving them in the process.

One-on-One Time Is Still Important

It’s easy to fall into treating the dogs as a pair, but each still needs their own attention. Training sessions, cuddles, and solo walks help maintain your bond and reduce potential rivalry. It also gives you the chance to work on individual needs—because no two dogs are exactly the same.

Summary

Getting a second dog can be wonderful, but it’s not always easy. It changes your daily routine, your dog’s world, and your household dynamic. It takes patience, time and flexibility—but with the right planning and mindset, it can also bring a new level of joy to your life. The key is going in with open eyes, a realistic view, and a heart ready for the chaos and the love.
