I didn't reply to this thread at the time it was posted because I had only just started to feed Molly home-cooked food. We are now almost 4 weeks in and I'm very pleased with how it's going - although it's more expensive than kibble, not cheaper!
I have struggled to keep Molly at an acceptable weight for several years. She was always ravenous on the amount of kibble she was supposed to have and made her feelings known by howling and hitting the fridge! Consequently my OH had taken to giving her an increasing amount of titbits which had also started to become less and less healthy options such as turkey balls and cocktail sausages. In December she really didn't seem well - she went on her walks as a duty rather than a pleasure and had several bouts of sickness. Anyway, I decided to make a complete change in food and joined the 'Home cooked diets for dogs' Facebook group, which has very comprehensive files.
So good news - Molly is losing weight, has miles more energy, has stopped being sick and isn't hungry all the time.
Because she is having lots of good quality ingredients (pollock, chicken, lambs' liver, vegetables, ground eggshells) my OH is not feeding her any additional snacks. At the moment I am weighing absolutely everything and give her 2% of her ideal weight (which the vet has said is 40kg - she is tall and long), which is 800g. She has 75% of her allowance as animal protein and 25% vegetables.
I think she is not hungry because with 800g of food I can feed her small amounts numerous times a day. She always had 2 hours of walks a day but now she is more active on the walks I hope we are into a positive spiral.
Molly loves the food and I hope that, in the same way I've been able to change my own eating habits and lose weight without feeling hungry, the same will be true for her.
