I can't really answer your q bc I mix the Acana w/NB SP&Venison. Mimi weighs 7#'s, Momo & Turbo 6#'s, lastly Princess is 5.5#'s. I feed them all the same amount, 3/4 cup split into 2 meals. The boys always want to eat more, but I can't feel their ribs...they're so heavy & chubby for their size. They also make widdle piggie grunting snorting sounds lol. The girls are nice & slender tho.
They all get daily walks & gets the zoomies couple of times a day. I guess the amount would depend on their energy level?
@Zhoie's mommy, sorry she was having problems w/Acana. I actually use a cough syrup cup. I give them 1 cup of Natural Balance Sweet Potato & Venison & 1/2 cup of Acana Grasslands. Princess has a very sensitive digestive system, her #2 will have little bit of blood in it or be on the soft side if she's stressed or eats something that doesn't agree w/her. When I made the slow switch completely to Acana, she couldn't handle it, so I'm mixing. Plus, I had 2 HUGE bags of NB left lol, so it actually worked out well. Hope you'll find a good solution for Zhoie.
