oh wow - her teeth must really really be bad - poor little girl -- it sounds like you're doing your best and I agree - I think the breeder should incur some of the cost OR refund the money you paid for her since it's worse than you thought. I'd be upset too if I didn't hear a word back after getting a yorkie that's this sick...you do fall in love with them quick ....it must be frustrating to be ignored by Sylvan - but from what I've read this last year or so - this isn't the 1st time she's done this to someone.
What a nightmare.... it seems she really needs to make some
major changes in her breeding 'program'.
or even better - maybe stop breeding. It sounds like she isn't in it for the dogs anymore just the $$
This is sad and it must be awful for your new yorkie. GOOD luck and I hope they can help her.
