I pay the neighborhood girl about $12/day to feed my dogs. She rides her bike to my house and feeds all 3 dogs- which takes about 20 min. total. She's a former student of mine, and I feel quite comfortable with her in my house. I was wondering myself if that's an OK amount to pay her, and judging from your responses- it's not too bad.
Now I have a new neighbor next door who offers to feed them for free when we're gone. I just buy him a bottle of wine and he's paid in full.
