Shiny Pokémon in Sword/Shield

Now that the games have been out a couple days, its time to start talking about one of the most important (or most inconsequential depending on your viewpoint, but if you clicked this thread than you're probably interested in it) aspects of any Pokémon games: finding shiny Pokémon.

Personally, I haven't found any shiny Pokémon yet, though I also haven't started looking yet either. If you have found a shiny (or more than one), then tell everyone about it here. Or maybe you have some advise on how to shiny hunt in these new games that you want to share with the world? Or perhaps you just want to discuss a specific new shiny Pokémon?

 

The other day I managed to breed a shiny Growlithe completely by accident. Wasn't even through the Masuda Method or anything, just pure chance. Certainly had me excited. Especially since its the new 'square sparkle' shiny variant that are ever rarer than the standard 'star sparkle' variant. I was absolutely flabbergasted when I saw him hatch and "Tiger" almost immediately became a major member of my post-game team even though I already had a couple good fire-types. Only problem is that I keep mistaking him for an electric-type because of his yellow fur (should probably teach him Thunder Fang).
That's the only shiny I've managed to get my hands on so far, but I think I'm going to start trying to actively shiny hunt now that I've completed the Pokédex.
