Would you be offended if I informed you (politely!) that your dog had done a poo if I knew you hadn't noticed (and that it was definitely your dog too!?
Very often, whilst pushing the buggy round the park, I'll see a dog walking behind its owner, stop and take a poo, and then trot back to its owners side and all the while the owner is unaware and the poo is left there to be stepped in/poked at by a toddler. Not that it should make a difference but this is in a city park so not a field in the countryside.
This happened today and I really wanted to say 'excuse me, you didn't see but your dog just did a poo over there' but I wasn't sure if it was not the done thing. What would you suggest I do?
