What Is Littermate Syndrome? Littermate syndrome is a term used to describe a range of behavioral challenges that can arise when two puppies, often siblings, are raised together. These challenges may include separation anxiety, aggression, resource guarding, and difficulty in training. As a professional dog trainer, I discuss this topic frequently and even wrote a blog titled “The Myth of Littermate Syndrome: Fact or Fiction”
Is littermate syndrome real? While many believe it is, I personally don’t agree with this label. In my experience, any multi-dog household can experience similar issues if the dogs’ needs aren’t properly met.
While it’s possible that littermates might be at higher risk, I haven’t seen conclusive studies that account for critical factors like how the dogs are raised and the training methods used. Whether you believe in the concept or not, the key is understanding how to prevent behavioral conflicts between dogs living together.
Let’s dive into how to raise two dogs in harmony and avoid potential challenges!
1. Start Training Immediately
Begin training your puppies as soon as they come home. Early training helps prevent undesirable behaviors from developing, such as separation anxiety, jumping, aggression, and resource guarding. By establishing boundaries and teaching appropriate behaviors early, you set the foundation for a well-mannered pair of littermates.
2. Avoid Punishment-Based Training Methods
Using aversive training methods like prong collars, e-collars, spray bottles, choke chains, yelling, or physical corrections can do more harm than good. These approaches rely on fear, pain, and intimidation, which can lead to frustration and aggression—not just toward you but potentially toward one another.
When we punish behaviors without addressing the root cause, dogs may become confused or frustrated, which can result in them lashing out at their littermate. This isn’t about them being “littermates” it’s a reaction to our poor communication and stress. Instead, focus on positive reinforcement to build trust and foster a peaceful household.
3. Train & Socialize Each Puppy Separately
Individual training and socialization sessions are crucial. Each puppy needs one-on-one time to bond with you and develop independence from the other. This practice helps them see being apart as a positive experience, reducing the risk of separation anxiety.
While working with one puppy, provide the other with an engaging activity, such as a frozen Kong, a lick mat, a puzzle feeder, or a chew toy. Pairing alone time with something enjoyable reinforces the idea that being apart is okay.
4. Teach Impulse Control
Impulse control is an essential skill for any dog, especially when there are two dogs in one household. Teaching behaviors like waiting for a release cue before walking through doorways or interacting with a resource helps prevent tension between the dogs. For example, if two dogs try to squeeze through a doorway at the same time, it can create frustration or even lead to conflict. By teaching them to wait their turn, you create a calmer environment.
5. Meet Each Dog’s Needs for Mental and Physical Enrichment
Dogs thrive when their mental and physical needs are met. This is especially important in multi-dog households to prevent boredom and the unwanted behaviors that come with it, such as excessive barking, fighting with one another or destructive chewing.
Provide daily physical exercise tailored to each dog’s age, size, and breed. This could include fetch, tug, chasing a flirt pole, or long walks on a 30-foot leash in an open area where they can explore for dogs who aren't as active or are not into toys. Mental enrichment is just as important—activities like snuffle mats, puzzle feeders, or foraging games can keep their minds busy and satisfied. By meeting their needs, you reduce the likelihood of conflicts stemming from frustration or pent-up energy.
In conclusion, whether you are raising littermates or not, the principles for success are the same: start training early, avoid aversive methods, train and socialize separately, teach impulse control, and meet their physical and mental needs every day.
Raising littermates or any dog can be a challenge, but you don’t have to do it alone. With the right support and strategies, you can help your pups grow into happy, well-behaved companions.
