This was one of the harder lessons I learned after switching to RAW. On the bag food i could take off the chain and they would dump within a few feet of the fence. Most under the same cedar tree. Then I switched. The first dog I worked (while being on RAW prior to the start of work) passed right by the tree and the Qtip thing did not work either.I put him on and empty spot, still nothing. After a couple of days I figured he just did not have one in him. On RAW I was just happy with the smaller and fewer dumps to clean up. But I learned I had to start counting them on a regular basis to get a feel for how many and how long after they needed to dump. I had to figure out how much I was putting in and how much they were putting out and gauge if a dump was needed. It took some time to get the dogs patterns down and then sync our schedules together.
