Daisy's currently on Royal Canin Junior Lab dry food which she's getting on well with. However I've been told on here it's not particuarly good really, and from Googling it appears it's also too high in protein (30%) - so I'm thinking of changing to Burns.
Anyway, the fosterer was feeding 120g a day, the Royal Canin pack suggests 265g a day for Daisy's age. Which is the right amount? Do I need to increase the 120g given that she's now doing a 15 min walk a day and is obviously getting bigger as well? I'm assuming I do, but am unsure exactly how much to give?
