Before I used to give them about 8 a day I think. That's too much, so now I give them about 2,3,or 4 a day. But depends on their behavior. On the bag of treats that I have, it says to give 14 to 18 pieces a day. I just think that's too much, and they'll be finished the bag very soon. Also, if we give that much, they won't think of it as a reward anymore.
