Having fed both foods to the same dog, I can honestly say I don't think I'd ever go back to feeding commercial food, unless something changes in the coming years!
There is reduced stools that don't smell nearly as bad, his breath is much fresher and the teeth cleaning is great for him, too. I think his coat has improved too. The only negatives I can see, are remembering to defrost it and perhaps in some areas sourcing the raw food may be hard too.
I also know exactly what is going into my dog, where as I think with commercial foods there are added chemicals that I don't necessarily want to put in my dog. The other negative is perhaps freezer space! Luckily we always have loads of freezer space as we have a chest freezer and our upright fridge freezer, so I have a draw from the fridge freezer and a section of the chest freezer, just for dog things.
