Have you ever heard about the littermate syndrome?
Littermate Syndrome is a common behavioral issue that often goes unnoticed until it becomes a serious problem. At our shelter, we see it frequently, particularly with sibling dogs around 8-10 months old, and often when they haven’t been spayed or neutered.
Many people don’t realize how prevalent Littermate Syndrome is, but it can affect any breed. It occurs when littermates become overly dependent on each other, leading to a lack of independence. This can result in a variety of behavioral issues, including:
🐾Separation anxiety when apart
🐾Fearfulness or difficulty with new experiences
🐾Aggression toward each other or other animals, as they struggle to establish individual identities
🐾Over-dependence on each other for comfort and support
🐾Training difficulties, as they may focus on each other rather than on learning from their owners
One of the more concerning aspects of Littermate Syndrome is the aggression that can develop between siblings. As they reach maturity, their dependence on each other can lead to territorial disputes, resource guarding, or even physical confrontations. This can be especially problematic when they have never learned to navigate relationships with other dogs outside of their litter.
To help prevent Littermate Syndrome at home, here are some important tips:
✅ Spay/neuter early to reduce the hormonal influences that can amplify the bond
✅ Separate training sessions for each dog to build individual confidence
✅ Socialize each puppy individually with people and other dogs to encourage independence
✅ Give them time apart to help them become comfortable being alone and learning how to navigate the world independently
Because of these challenges, we do not adopt out sibling puppies together. By adopting separately, we ensure they have the best chance for healthy development and become well-adjusted, confident adults.
If you’re adopting, remember: encouraging independence early on is key to helping your puppy grow into a happy, balanced dog. 🐕💕
