Had to laugh the other day when walking my 6 month old BC pup.  She played fetch with her ball - which was an achievement because she would not play when out for walks - only at home.  After a while she just weed on her ball - it did look deliberate - and then walked off.  Maybe she was leaving it there until next time?  Anyway I had to pick it up and carry it home!!!!!  Lucky I had spare bags.

Lol...My two went through a stage where they stole each other's toys and then peed on their booty! :-)
