Looking for info about millies wolfheart plz

Hello,

Looking for some feeding guidance for millies wolfheart please. I've been scouring the internet for a food that would be suitable to feed both my senior and puppy, and stumbled across millies wolfheart.

I've decided i'm going to give the countryside mix a try for the both of them. However, i'm unsure which size bag i will need (i'll order a taster bag for now) in the long term.

If anyone uses millies wolfheart could you please forward on the feeding guide, specifically looking for the feeding suggestions for a senior dog of 25kg and puppy whos adult weight will be approx 5kg, she is about half that at present.

Thank you for any help
