Patties are pressed at 8 ounces as they come through our patty machine. Please keep in mind that as the patties thaw during transit or are thawed at home and then weighed this will affect the weight as raw foods tend to be 60% or more moisture. Our products are binded in the mixer with the blood of the animal we sourced, any loss of moisture due to thawing will reduce overall weight slightly. Example: When thawing hamburger from the freezer and thawed in the fridge tends to leak, this is actually myoglobin and mostly water that is released. This is the same with your raw dog food.
