[Dailydrool] Picky aged eater

[Riche Churchill]

Am looking for suggestions to get a picky eater to eat. She's 15 and 
healthy, but IMO spoiled rotten and the DP gets frantic when she won't 
finish her meals. Granted, one's appetite often decreases with age, BUT 
this rotten dog would eat Ol' Roy "rounds" or biscuits till your arm 
fell off handing them to her -- just not the 10 or so various expensive 
kibbles we've tried. She won't touch raw meat or cottage cheese or 
yogurt. Mixing her kibble with cooked ground beef did not work (although 
she probably would have eaten it if not mixed in with the nasty kibble). 
Personally, I would just let her eat the Ol' Roy rounds, but I am not 
the boss around here.

Since there are 8 other eager-eaters around here, there is a limit as to 
how far I'm willing to go cost-wise to get her to eat "good" food.

Suggestions?
