Littermate Syndrome in Dogs? – Pet owners commonly prefer to adopt two siblings from a single puppy litter when they decide to bring home puppies. Having siblings in the same group may result in littermate syndrome as an outcome. The bonding behaviour of puppies gets impacted by this condition in their relations with other animals and humans and their surroundings. The practice of raising two puppies together creates excessive interdependence between them so they face emotional and social difficulties later in their life.
What Is Littermate Syndrome in Dogs?
The situation of two family-born puppies sharing a common risk factor for littermate syndrome develops when they remain together throughout their lifetime from birth until maturity. The arrangement of keeping two puppies seems attractive to start. From infancy until their maturity the two puppies develop their relationship through physical interaction. First-generation puppy relationships tend to develop into permanent difficulties which affect the health of affected pets.
The extended amount of time puppies spend together makes them grow up to be dependent adults. Social contact between puppies during development leads to negative social skills that result in a need for emotional attachment to family members. Uninformed separation leads dogs to form separation anxiety and also creates fear toward being alone as well as difficulties with new encounters involving humans, dogs or environments.
Specific attention levels toward certain puppies cause them to learn improper behaviours from their cohorts in the natural process of rivalry. The constant concentration with friends during their development keeps dogs unable to build self-awareness. Deep friendships based on closeness create extreme dependence between friends who lose their capability to relate to unfamiliar people while working independently.
So, what can you do?

Having plans to adopt two puppies should not worry you because you will succeed at raising them properly. Just be sure to:
- Devote separate periods of quality interaction to each puppy individually.
- Training them independently ensures better concentration during their individual learning processes.
- Allow your puppies to visit new locations while making contacts independently from each other.
- Your effort to separate training will lead puppies toward becoming confident household pets who connect peacefully with people while getting along with other pets in any situation.
