I've been looking on All About Dog Food for the holy grail of food that's both cheap and nutritious.
I've noticed that the ones that fall into this category seem to be cold pressed e.g. Markus Mühle and Guru. However, they seem to achieve their low estimated daily costs by saying you require less - about 72g / day for a 6kg terrier that's currently eating almost double that weight of pricey Canagan!
Is this realistic, or would I actually have to significantly increase the quantity / end up with a perpetually hungry dog because there isn't the volume to physically fill his stomach?
