My dog w/kidney stone issues doesnt like Hills U/D

Question
Hello.  2 years ago our Lhasa Apso had kidney stones.  One
was so severe, she became very ill, was hospitalized and
nearly died.  Thankfully, they were able to break up the
stone and she made a full recovery.  Because of this,
however, we had to put her on Hill's U/D.  She ate it fine
for a while but over time became less and less interested in
it.  We have a strict list of other foods she is allowed to
have (chicken, rye bread, carrots, and a few other things
but those are the most successful) in small amounts and have
tried adding these to her food with only some success.  
Feeding her is ALWAYS a huge challenge as she just isn't
interested in the food.  We want to keep her on a diet that
is best for her and not just feed her regular dog food.  The
vet has no further suggestions.  We've also tried the Royal
Canin and she doesn't like that at all.  She eats most but
not all of her food but not without us adding things to it
and not without HUGE effort.  Is there some sort of
flavoring that is made to make the food more appealing or
something else you might suggest trying?  Thank you.

Hi Karen,

Sorry I have to keep doing this, but a dog like yours should either be on a prescription diet or a professionally formulated home made programme, designed to mimic the U/D but using better ingredients. I do this for a living, and have developed hundreds of such diets now with outstanding results. If you'd like to discuss this option please visit my homepage at www.thepossiblecanine.com and check under Services.  If you don't have someone with training and experience formulate the diet, using precise nutrient levels,  you may succeed at making it palatable but eventually exacerbate the stone problem. I'd like to help more, but I feel unethical handng out a generic diet for a dog I know so little about. My nutritional philosophy is holistic, meaning I feed the whole dog, not *just* a condition.
Please feel free to contact me if you'd like to discuss this further, or I have to say - manage the condition and stick with the diet.

All the best, Catherine
