She's probably on the other side of the house. The big dogs only mess with Sasha (the smallest chiweenie). Sasha I think is also the Alpha as she looks like she's fussing the big dogs all the time. Tasha on the other hand, will play with her sister when the big guys aren't around otherwise, she'd rather be napping in the flower beds. But let someone come near the fence and she's up and barking with the rest of the pack in full attack mode!
