Hi there.. 
I'm new to the forums but have had my tea cup yorkie for 10 years.. she's an old girl but i adore her.. 
over the last year an 1/2 my girl has gone blind (cataracts) and while I know she can have surgery she does not do well under anesthia..we almost lost her when she was younger while getting fixed.  
anyways.. while she gets around well, eats ...her skin is always an issue.. we've medicated, i bath her, groom her, everything.. she's not got a patch of hair missing on her back.. there is also missing teeth again because we can not put her under to have that handled.  
the last 2 nights she is up all night pacing, whining, barking to get my attention.. it fries me as I have to work in the am.. but I don't know what to do.. she just whines to get on the bed, whines a few mins later to get down and then paces and barks at me.. then wants back up and the process starts all over again.. last night she final settled in about 3am till about7.. and it started again.. 
does anyone have any advice, or clues as to why this might be happening? 
any and all advice would be helpful... 
thank you 
me and Miss D
