Training
Border Terrier
- **: Positive reinforcement with high-value food rewards is essential. Harsh methods cause them to shut down or become defensive.
Miniature American Shepherd
- Use clicker/marker training - highly effective
- Never use harsh corrections - can cause shutdown or fearfulness
- Teach 'Leave It' early for cat/small animal safety
- Channel herding drive into appropriate activities (agility, disc)
Miniature American Shepherd Considerations
Strong genetic drive to control movement, often nipping at heels of running children, chasing bicycles, or herding pets. Not aggression, but alarming for unprepared families.
These are 'Velcro dogs' that bond intensely with their handlers. Can suffer severe distress when left alone for long periods, leading to destructive chewing and excessive vocalization.
Naturally observant and protective. Without proper socialization, can escalate into reactivity toward strangers or other dogs. Vocal watchdogs that alert to any environmental change.
Need activity Tuesday morning just as much as Saturday afternoon. Under-exercised MAS become destructive and develop behavioral issues.
Multi-Species Compatibility
| Species | Border Terrier | Miniature American Shepherd |
|---|---|---|
| With Cats | Caution - may chase | Generally safe if raised together, but will chase if the cat runs |
| Small Mammals | Supervision required | Moderate risk - high prey drive means hamsters/rabbits should be kept secure |
| Birds / Reptiles | Caution advised | Caution advised due to chase instinct |
Advanced Behavior
| Trait | Border Terrier | Miniature American Shepherd |
|---|---|---|
| Predatory Sequence Risk | Medium | Arrested |
| Biddability | Low | High |
| Noise Sensitivity | Low | Low |
| Territorial Barking | ||
| Same-Sex Aggression Onset | 18 months | N/A |
Miniature American Shepherd: Predatory sequence: Eye -> Stalk -> Chase -> Grab/Nip (kill inhibited). Will chase cars and kids - the nip is a herding correction, not aggression. Very high biddability - finds social reward highly reinforcing.
