Should You Adopt Another Dog? 7 Signs Your Dog Is Lonely

Dogs are social animals by nature, and while some are perfectly happy being the only pet in the house, others may crave companionship—especially if they’re left alone for long periods. A lonely dog can develop behavioral problems, anxiety, and even depression, making life harder for both them and their owner.

If you’re wondering whether your pup could use a four-legged friend, here are 7 signs your dog is lonely—and what to consider before adopting another dog.

1. Your Dog Clings to You Excessively

If your dog follows you everywhere, constantly demands attention, or refuses to let you out of their sight, it could be a sign of loneliness and separation anxiety. While some dogs are naturally affectionate, excessive clinginess can indicate that they lack social interaction and may benefit from a canine companion.

2. Destructive Behavior When Left Alone

Does your dog chew furniture, shred pillows, or dig holes in the yard when you’re not home? Destructive behavior is often a sign of boredom and loneliness. A second dog can provide entertainment and companionship, reducing the likelihood of acting out due to stress or isolation.

3. Your Dog Sleeps Too Much (or Not Enough)

Dogs who feel lonely or depressed may sleep excessively, simply because there’s nothing else to do. On the other hand, some lonely dogs struggle to rest, becoming restless or pacing when left alone. If your dog’s sleeping patterns have changed, they may need more social interaction or mental stimulation.

4. Loss of Interest in Playtime

A dog that used to love fetch, tug-of-war, or running around the yard but now shows little interest in playing may be feeling lonely. Dogs are naturally playful, and a loss of enthusiasm can be a sign of boredom or emotional distress. A second dog can bring back their playful side by providing a constant companion for games and fun.

5. Your Dog Cries or Whines Frequently

Excessive whining, barking, or howling can indicate that your dog is longing for companionship and attention. Some lonely dogs even vocalize at night, hoping for comfort. If your dog seems unusually talkative when left alone, they may be expressing separation anxiety or loneliness—a problem that could be eased with another dog in the home.

6. Your Dog Seeks Attention from Other Dogs

If your dog immediately runs to greet other dogs at the park, plays enthusiastically, or seems happier when around other canines, it might be a sign that they’re missing daily dog-to-dog interaction. While human companionship is important, many dogs feel happiest when they have another dog to bond with.

7. They Show Signs of Anxiety or Depression

A lonely dog may develop generalized anxiety or even depression, which can manifest as:

• Pacing or restlessness
• Loss of appetite
• Lack of enthusiasm for walks or activities
• Lethargy and withdrawal

If your dog seems down or disconnected, it could be because they are missing companionship and social engagement—a role that another dog might help fulfill.

Should You Get Another Dog?

Before adopting a second dog, it’s important to evaluate whether your home, lifestyle, and current dog are ready for another furry friend. Here are some things to consider:

Is Your Dog Social?
Some dogs love having canine companions, while others prefer to be the only pet. If your dog has a history of aggression or disinterest toward other dogs, they may not enjoy having a sibling.

Do You Have the Time and Resources?
Two dogs mean double the expenses, training, and time commitment. Make sure you’re financially and emotionally ready for the added responsibility.

Is Your Home Big Enough?
Dogs need space to play, sleep, and eat comfortably. Ensure that your home can accommodate two dogs without causing territorial disputes.

Are You Ready for an Adjustment Period?
Introducing a new dog takes time. Your current dog may need weeks or even months to adjust to a new sibling. Be prepared for training, supervision, and patience during the transition.

Is Your Dog Ready for a Friend?

If your dog is showing clear signs of loneliness, adopting a second dog could provide companionship, comfort, and stimulation—but only if it’s the right fit. Not all dogs want or need another dog, so carefully assess your pet’s personality, lifestyle, and social needs before making a decision.

If you do decide to bring another dog into your home, introduce them gradually, monitor their interactions, and allow them time to bond naturally. A well-matched companion can improve your dog’s happiness and well-being, creating a loving, lifelong friendship!
