Hi Maximo
Thanks for coming back to me sooooo soon. Bella has a number of "difficulties. She had swelling of the brain (which caused some pressure). She also has a problem with her spine - apparently some Yorkie puppies do have this problem but outgrows it. And then, she got poisoned. She only goes out when she needs to go to the loo. And I don't have anything remotely dangerous around my apartment that she can eat. Which means that she ate something outside.
I took her to the vet and he gave her a new shampoo. It seems that her skin is very dry and it can be from the shampoo I was using.
So you probably can understand that I get very frantic when she is not her normal self.
Thanks again.
