He even avoided the grazing Pink and Grey Cockies by walking around them.
A pink-n-grey I had a few years back used to do the rounds of our dogs [rottie, lab, and kelpie] and pluck prickles out of their fur.
Even caught her searching for grass seeds in the rotties ears a couple of times

My last p-n-g loved preening my beard and removing the grey whiskers.
The rottie and lab used to live in our little supermarket / hardware / stockfeed shop in the country, and "share" the tennis balls with marauding customers, however, it was pretty common for our checkout chick to find soggy tennis balls mixed in with peoples shopping.
The main giveaway that a tennis ball was hidden in a trolley was the whimpering rottie standing with her toes juuuuusssst outside the door, while she leaned in as far as possible without falling over.
Usually the shop cat was standing about 2mm out of reach - nose to nose with the rottie - daring her to come in any further.
A blue heeler on the farm in Williams was magic at removing grass seeds from your socks -entirely self taught.
But you had to be quick to pay him with a biscuit or crust, or your boots were soon on the far side of the paddock.
Always had a damn good run with our pets, although I am tempted to turn the sandwichmakers ragdoll cat into a hat when it wakes me at 3am to tell me there is evil residing in her litter tray.

Doesn't matter what the animal is, train it right and its not a pet - more of a mate.
