We took on my parents Jack Russell terrier Toby when my parents became too frail.
He was a bit “whiffy” so I shampooed him with a pleasant herbal shampoo designed (supposedly) for dogs.
At the time, we lived near Battersea Park which was home to large numbers of Canada geese. We headed there for our evening stroll. Within minutes of entering the park he’d rolled in goose poo and came marching back to us, tail wagging, with a smile on his face saying - “There, I smell MUCH better”.
I threw the shampoo away.
