Yorkies start changing teeth at about 4 months (like little Maggie
) And usually in a few months most of her baby teeth will fall...i think the remedies would be the same we have with a teething baby, you can put her toys in the fridge, even give her doggie ice cream...also chew toys are great to help speed up the process.
Oops, forgot to say, i used to give Mojo frozen apple and baby carrots...he loves it (specially carrots...he may even think he is a rabbit..heheh)
