Hi!
Our dog was on kibble for most of his life.
He was mostly on Wagg.
Then when he was approx eleven, he unfortunately developed a cancerous tumour, and first vet could only offer amputation at best or to be put down.
Second vet sorted him out without amputation... yay!
We then decided to try him with raw food.
Unfortunately no brand name, as we bought it from a large warehouse in a rural area that supplied everything to animals small as a mouse to as large as a horse.
Point of me posting is that even an older dog such as ours was, he took to raw food with a passion.
It's not as convenient as serving kibble, but seeing the enthusiasm in our dog's behaviour when mealtime arrived, made it all worthwhile.
We gave him half a bowl of raw meat, along with grated raw carrots, swede, and any veg apart from the ones dogs aren't allowed, he loved raw red cabbage mixed in it too.
The amazing outcome of that, was when I collected his poo from the back lawn, it had a blue hue!
Bonus was, his poo was never as smelly as it was when he was on kibble, and he went on to live a further healthy three years post recovery.
So our experience of a raw diet for our dog was a positive one.
He was a mixed breed, but id say he was the size of a German Shepherd.
Hope you find a good supplier in your area.
Best wishes.
