How To Avoid Littermate Syndrome
Littermate Syndrome is a behavioral issue that can occur when two sibling puppies (especially of the same age and breed) are raised together. They may form an intense bond with each other and struggle to develop social skills with humans or other dogs. This can lead to anxiety, aggression, poor training, and fearfulness.
While not guaranteed in every pair of puppies, littermate syndrome is a real risk, and most dog behaviorists advise against raising sibling puppies together unless you’re highly experienced.
✅ How to Avoid Littermate Syndrome
1. Consider Adopting One Puppy at a Time
- The best way to prevent littermate syndrome is to only bring one puppy home at a time.
- If you want two dogs, adopt the second after the first is trained and socialized (usually after 6–12 months).
If you already have two puppies:
2. Train Each Puppy Separately
- Conduct separate training sessions so each dog learns to listen to you, not just follow its sibling.
- Teach basic commands and behavior individually.
3. Feed Them in Separate Areas
- Prevent resource guarding and dependence by giving them individual meal spaces.
4. Crate Them Separately
- Use individual crates in different areas of the house.
- This helps build independence and self-soothing skills.
5. Socialize Them Separately
- Take each puppy on individual walks, vet visits, and outings to expose them to new people, sounds, and dogs on their own.
6. Play with Them Individually
- Give each dog one-on-one attention to build individual bonds and reduce over-dependence on the sibling.
7. Watch for Red Flags
- Be alert for signs of:
- Anxiety when separated
- Aggression or excessive fighting
- One puppy becoming overly dominant or withdrawn
Why Littermate Syndrome Is a Problem
| Issue | Result |
|---|---|
| Over-bonding with sibling | Puppies rely on each other, not humans |
| Poor social development | May fear other dogs or people |
| Training difficulties | Less responsive to commands when separated |
| Separation anxiety | Distress when not near the sibling |
| Behavioral issues | Fighting, dominance, or submissive behaviors |
🐾 Final Tip:
If you already have a bonded pair and are struggling, work with a certified professional dog trainer or behaviorist who has experience with littermate syndrome.
