Dog was acting weird for a moment (not a health issue)..?

Some dogs go a little nuts when a wild or domestic animal uses the bathroom on their property.. they can pick up on human smells to! Anything really.. It could have just been excited and wanted to play.. perhaps it burried something there and just wanted you to know? Also, if you live in the United States, there is no real worry with rabies.. especially if they have their shots! Now that the dog is calm, and as long as it's eating.. There is nothing to worry about! :)
