Pet Care Needed - Full-time / Part-time

Our 3 dogs: Izzy (Black Lab 5yr), Petey (American Bulldog), and Billie (Australian Shepherd) are all very friendly. We need them to be fed twice a day, earlier in the morning and late afternoon. After they eat they all go outside to their 1/2 acre fenced in yard. They all expect to get a small treat ;) when they come back in.
