Query: WOW, THIS IS THE BEST BOOK!!!!

I PURCHASED THIS BOOK BACK IN JULY' 2008. IT CAME IN SO HANDY IN HELPING ME DEAL WITH MY "SOUL MATE", LITTLE ALI, WHO HAD CUSHINGS... I AGREE WITH ALL THE FIVE STAR RATINGS THAT OTHER PEOPLE WROTE REGARDING THIS BOOK.. I ENDED UP HAVING TO PUT MY LITTLE GUY TO SLEEP IN 2008... BUT NOW I HAVE A YORKEE WHO WAS JUST DIAGNOSED WITH DIABETES, AND LET ME TELL YOU, THIS BOOK ONCE AGAIN IS MY GUIDENCE FOR TAKING CARE OF MY LITTLE GIRL, ISABELLA!! THANK-YOU CAROLINE D. LEVIN, THE WAY YOU WROTE THIS BOOK MADE IT VERY EASY TO UNDERSTAND, DOGS, DIET, AND DISEASE. WANDA...R.I.
