$30 · PC brand Large Breed dog food, nearly full

We got this food for our dog but he is not adjusting well to it so we are switching him to a sensitive skin and stomach option. The bag is nearly full and I really don't want the throw out so much perfectly good dog food, never mind it costs about $45. This is the 18kg bag and he probably ate about 1.5kg out of it. If your dog is on this food already or you plan to switch to it hit me up. 6o4-69o-7359 Cheers
