Interesting facts: Onion’s a bit of a local celebrity along Portobello Road and there’s nothing he loves more than having a little poke around. At the ripe old age of eleven years, like most, Onion loves a good feed. If you’re going on a road trip, then he’s your perfect companion in the passenger seat but be warned, don’t scratch his ears or belly. If you’re another dog you’d better stay clear because he’s not a fan. One last thing, never ever ignore him, that’s one way to fast-track into his bad books.
