Did you rinse her really well after the bath ? If so, then I'd have someone check her for ear mites - you can google them to see what they look like (they leave residue in the ear) and are easily treatable
It's also possible she may have a flea problem since she's scratching all over -those suckas can be really hard to spot !! Your yorkie is very very young so I wouldn't self-treat - I'd see a vet about it if you can, |
