Yes, that's right, one of my dogs lifted his leg and peed on a poor innocent man at the park! I was talking to this man (he is a park regular) and by the time I noticed what the dog was doing I couldn't move/get the words out fast enough to stop him! This dog is one of my best behaved and oldest clients - I have no idea what got into him! So, besides the fact this poor man had to walk around with pee on his leg, and it was an extremely awkward experience for all, it was pretty damn funny!
