I am the Free Feeding Floosie :D
and while we just had Kailee it worked very very well. I measured her daily portion of kibble out into her bowl in the am. and by night time it was usually gone. If I needed to know what her daily intake was I just measured the am't at the end of the day and subtracted. As well, if in the next am. there was still one cup of food left, then I only added 2 cups giving her the 3 cup portion daily.
However....enter Clyde to our family on March 9th. I continued for about 2 weeks using the Free Feeding Floosie method (I am not being rude towards anyone, I was dubbed this name once in gest, and I found it quite funny, in fact I quite liked the title) Within that 2 week span, I put 3 cups in each of their bowls. Clyde was not gaining, but Kailee sure as heck was. Hmmmm...I observed more closely one evening when I was home (I am rarely here in the evenings due to work) that Kailee was eating ALL of her kibble, then chomping on Clydes as well. Seems she was allowing Clyde to have just over 1 cup of kibble per day, just enough to keep him walking

So now I had no control over the intake she was getting, nor Clyde. Poor Clyde was inching out to the kitchen after the

was done and ate what was left, all the while watching for Kailee to reappear.
I have had to restructure my feeding practices. Kailee was definatly becoming Alpha, and we were losing our status with her as well, not to mention Clyde was most likely hungry. They now get fed 2 times a day, and the bowls are taken up when they walk away from the bowl. Don't tell Kailee but, she is getting less food per day as she now needs to reduce drastically. Clyde on the other hand has gained some much needed weight and is looking good.
Free feeding does work in some situations but not all, and I do believe for sure in multi dog homes it does not work at all. I have never yet found Tulsa Dan to be negative in his opinion, he states facts and advises accordingly. Although he and many others did not agree with my Free Feeding practices, I was never told I was really doing something wrong, they just pointed out it can cause issues in behaviour. I do believe strongly, if you are dealing with a dog that has some behavioural issues that you need to correct, than yes, Free Feeding is not the way to go.
