Hi Sanne,
I would give “Farmina Ancestral Grain” a try it’s made in Italy, it looks like a very good quality dog food, then I’d try “Victor Select” I think the Victor Select Chicken looked really good when I was looking.
I also feed “Canidae Pure Meadow” Senior formula it has all the supplements for aging dogs joints/bones, skin & coat, it’s high Omega 3 fatty acids & Glucosamine..

Rotate between a few different brands thats what I do, so if something is wrong with 1 brand then my dog isnt eating it for too long to have any bad side effects..
