Thinking of adopting two puppies at once? We need to talk.
We get asked all the time about adopting two puppies together—either as playmates or because they’re thought to be a “bonded pair.” While it sounds sweet in theory, there are serious behavioral risks that come with raising two young puppies at the same time, whether they’re littermates or not.
Because of these risks, our rescue does not adopt out two puppies to the same home.

🚫 What Is Littermate Syndrome?
“Littermate syndrome” refers to a range of behavioral issues that can occur when two puppies are raised together. It doesn’t just affect littermates—it can happen with any two puppies.
Puppies with littermate syndrome may:
• Become overly bonded and codependent
• Struggle to function independently
• Show anxiety, whining, or destructive behavior when separated
• Experience delayed training and poor social skills
• Become reactive or fearful of people, places, or other animals
These issues are tough and expensive to manage—and sadly, they often lead to dogs being returned or rehomed.

💔 The “Bonded Pair” Myth
Two inseparable puppies may seem like a “bonded pair,” but it’s usually codependence. One pup often becomes the confident leader, while the other grows insecure and overly reliant. Neither dog learns to thrive on their own, and the timid pup is more likely to develop fear or reactivity.

🎯 Our Priority: Long-Term Success
Our goal is to set every dog—and adopter—up for success. That means adopting one puppy at a time, so they can become confident, well-adjusted adults.
When your first puppy is thriving, a second dog may be a wonderful addition! But it’s a decision that should come with time, experience, and planning.

We know it’s hard to say no to two adorable faces, but adopting one now and waiting until they’re ready is the best thing you can do—for both dogs and for your future self.
And if you see a rescue or breeder allowing two-puppy adoptions, ask why. Sadly, money can be a big motivator.
