A few days ago while I was out of town my sister took my Russian Tortoise outside and played on her phone for 20 minutes and he walked away. I came home yesterday and was told what happened. A dog tracked his scent to the creek in my backyard last night but couldn't find him. I went out this morning and looked for him in the creek and put up signs but I'm really worried. I live in Columbia, Maryland and my number is 4438892980. If anyone knows anything or has any tips please let me know.
