My Yorkie is a strange little thing.
She loves toast, like totally obsessed with it. She would choose toast over meat any day.
She HAS to bring my mam a present every single morning, they are usually either socks, toys, or anything else lying on the floor that she can pick up. She gets really distressed if she can't find something to give to her.
When my other dog does a wee or poop in the garden, my yorkie with run round and round her in circles.. kinda like a lap of honour.
She likes it when you blow on her tummy, and she will lie across your face until you do so.
She also stands/sits on her back legs like a meerkat a lot.
