Mika Brzezinski has gone to the dogs -- in a good way -- after Donald Trump viciously attacked her.
The MSNBC anchor was out walking her 2 pooches Thursday in NYC ... with a curious letter emblazoned on her sweatshirt.
In case you've been under a rock all day ... Trump went on a tantrum Thursday morning, calling Mika stupid and crazy before saying she was "bleeding badly from a face-lift."
Mika was back to normal just a few hours later.
Mika: 1, Trump: less than 0.
