She was standing on our porch shaking. I eased over to her and she ran off. I left her some dog food and water and came back 2 hours later and found her again on the porch. She looks like a little terrier and weighs about 20 lbs. She knows how to sit and shake, so somebody spent a little time with her. She has no collar, so What would you all recommend? Found her in the McDonald area.
