                                 Dicalcium phosphate***                    2.9 grams (3/4 tsp)
                                 Salt substitute (potassium chloride)   1.9 grams (1/3 tsp)
                                 Balanced vitamin/trace mineral supplement

* Note:  Owners are encouraged to feed
the highest fish oil dose tolerated by the dog.

** Calcium carbonate is available as oyster shell calcium
tablets or Tums tablets (0.5 g in regular Tums, 0.75 g in
Tums Extra and 1.0 g in Tums Ultra).

*** Bone meal can be used in place of dicalcium phosphate.

Directions:
Cook the rice with salt substitute added to the water. Cook
the ground beef and drain the fat. Cook the liver and dice
or finely chop into small pieces. Pulverize the calcium
carbonate and vitamin/mineral tablets. Mix the vegetable
oil, fish oil (break open capsules) and supplements with
the rice and then add the cooked ground beef and liver. Mix
well, cover and refrigerate. Feed approximately one-third of
this mixture each day to a 25-30 pound dog. Palatability
will be increased if the daily portion is heated to
approximately body temperature (Caution: when using
microwave, avoid hot spots, which can burn the mouth).
