I ordered this food after seeing it advertised in my monthly dog magazine, having struggled for 2 years to keep my allergic bulldogs weight down. She normally ate the normal jwb due to her intolerances. She has had to endure a small daily ration weighed every morning on the digital scales to ensure she wasnt getting too much but was still topping the scales at 30kgs! a few months later winnie has lost an amazing 4 kgs! Cant recommend this food highly enough, it is a 12kg bag but fills the 15kg bin as the kibbles are lighter the dogs can have more in their bowl for same weight. Winnie is happy and so is mommy! Brilliant product, our 10 yr old basset hound also eats this quite happpily even tho she has no weight issues and is maintaining her normal weight!
