All we had to do was ask, "Who's that? Who's outside?" Tia would jump on the chair, Tiger as well, and Tia would bark and wag her tail. Company? Who's there? She always barked at the doorbell, bounded toward me when I came home and licked my kneecaps.
The photo of Tia and Tiger outside was taken before our Florida room was rebuilt. Tia always sniffed around outside, snooped, investigated while Tiger is more sedate and an indoor dog. She was such a happy dog.
