Pet Care Needed - Full-time / Part-time

My dogs are ages 2yrs (Boerboel Mastiff), 3yrs (Yorkie Poo), 4yrs (German Shepherd mix), & 5yrs (Italian Greyhound mix). They like to go outside for short periods of time in a fenced in area and stay in the house for rest of the time. They are house broken. They are very affectionate loving fur babies that love lots of belly rubs, doggie snacks, and their toys.
