Thought you only had cats. ?

Our border collie dug a great big hole in the backyard doggie fenced area a few days ago, and then came in the house (through the doggie door downstairs) with muddy feet! She never does that!! Maybe she was going after a mole? Usually she comes to the front door after she has been out roaming the neighborhood, and if she has wet, muddy or dirty feet, she will wait patiently on the front porch for us to come out with a towel/rag to wipe her down before she comes in. She is usually very polite that way!

What kind of dog do you have?
