Dennis did loose weight with it - he was a kg overweight when I started feeding it and he only has a quarter kg to go now to get to breed standard. It was easier to portion control the Healthy paws as I could give him less than the recommended amount on the packet yet he is still satisfied he is getting enough food - it didn't look like I was starving him looking into the amount in the bowl. Before Healthy paws I tried the Eubekanuba light and when I reduced the portion his bowl appeared empty.
When he gets to his ideal weight I will feed him the amount recommended on the packet for his weight.
Like your GR, Dennis also had hot spots which he liked and chewed until they were red and sore, he doesn't do this now.
