It works ! But poor dog seemed constantly hungry
So it definitely works in terms of weight loss ! My Frank has Been on Wolf of the wilderness for 5 years ( he’s 6 ) he’s gone from wild boar ( his favourite ) I kept the quantity I feed him the same & I felt like he was constantly hungry, eating paper & things he hasn’t since being a pup so I ended up giving him bigger portions . He lost about 5k ( about 36 to start ) in about 2 months , once I was happy where he was at , I now changed to endless terrain , seems to be keeping him happy
