[quote=cawkazn]so would a full grown dog, that is about 100 lbs, need 1 rabbit a day or what? 2 guinea pigs a day?[/quote] 2% of Body Weight of the Dog is a gennerally accepted starting point. So, a 100 dog would eat 2# a food a day. From there you look at age, amount of excersize, if the dog is indoors or outside, dog's metabolisim. I'd tell you to start at 2#s and after a week look at the dog's condition and energy. I pay more attention to that than the scales. BTW - Those western Jack Rabbits are twice as big as our eastern bunnys. :lol:
