Behavior: Everything You Need to Know About Littermate Syndrome

You might have come across the term "Littermate Syndrome" or littermate dependency in the context of raising two puppies from the same litter together. This phenomenon entails certain behaviors that emerge when these littermates are raised side by side. Such behaviors can include a strong attachment to each other, difficulty in forming bonds with humans and other pets, instances of aggression, separation anxiety, and a decreased willingness to respond independently to training cues. Interestingly, these behaviors can manifest between any pair of puppies or dogs who are raised concurrently, irrespective of their actual sibling relationship.

The Controversy: Is Littermate Syndrome Real?

The concept of littermate syndrome sparks discussions among dog trainers, breeders, shelter staff, and animal professionals. However, it's important to note that this "syndrome" isn't officially recognized by leading veterinary behaviorists or experts in the field. Instead, the behaviors often linked to this notion likely stem from the challenges that arise when raising two puppies simultaneously.

Why Do These Behaviors Arise?

Raising a single puppy is already a demanding task. Teaching social skills, house manners, socialization, training, and management is no small feat when focused on one pup – now imagine juggling these responsibilities with two furry bundles of joy. When handling two puppies, it becomes a challenge to ensure that each one has unique experiences separate from their sibling.

Unpacking Key Aspects

  1. Socialization: Puppies learn extensively during their socialization phase, getting accustomed to their environment, humans, other animals, and more. The quality of each encounter matters. Every puppy should feel secure, given the time to explore and form positive associations at their own pace within a controlled yet positive setting.
  2. Housetraining: Teaching puppies proper elimination habits is a critical part of puppy rearing. This involves guiding them to eliminate in designated areas and building healthy bathroom routines. While most puppies catch on swiftly with consistent training, not all progress at the same rate. Handling two puppies in this phase can be both taxing and challenging.
  3. Guiding Behavior: Puppies will exhibit chewing, nipping, jumping, and other behaviors that might not align with your household rules. Redirecting these behaviors is crucial, and ensuring the environment is "puppy-proof" is a must. Providing mental stimulation through puzzle toys, exercise, rest, and positive reinforcement helps curtail these behaviors. However, managing this with two puppies can inadvertently reinforce undesirable habits.
  4. Training: Training is a vital learning process for both the pup and the human. It provides mental enrichment and imparts essential social skills. Basic cues like "touch," recall ("come"), and settling on a mat are valuable for all puppies. While training presents opportunities for growth, working with two puppies simultaneously doubles the challenge.

Are There Instances When Two Puppies Are Better?

Indeed, there are cases where raising two puppies together can yield positive outcomes. Some littermates may develop strong, healthy bonds and well-adjusted behaviors. If you opt for raising two puppies, ensure they receive individual training, socialization experiences, and personal attention. This approach fosters their overall well-being and ensures balanced development.

In essence, the idea of littermate syndrome isn't solely about bonding issues or behavioral troubles arising due to sibling relationships. It's more about the complexities encountered when raising two canine companions concurrently.
