Hello Smudger doesn't get any human food at all, my mum has always given her yorkie human food and she has very bad teeth. She has actually had 5 teeth fall out and she is only 7
I'm not saying this happens to all yorkies I'm just saying I don't see it as essential for them to have it. He gets enough treats of his own.
Oh and also didn't want him begging at my feet like my mums yorkie does
