Derby doesn't do the poopy circle thing. But I can tell he is getting ready to go cuz his tail goes straight out and his back legs start to get wider an wider as he walks to find the right place. This is funny.....last week we were walking from my house to downtown and my friend had ahold of his leash and all of a sudden we were crossing in the middle (of a not very busy street) and good ole Derbs copped a squat right in the middle of the street. HAHAHA! My friend started freaking out and saying....omg, what do I do....what do I do? And I wasn't sure what he was talking about and I turned around and Derby layed one out in the middle of the street. Some guys that were crossing in a car the other direction rolled down their windows and cheered for Derby. Boy was he just so happy with himself afterwards. I swear he felt a lot lighter cuz he sure did pick up the pace.
