I bought the 30lb bag because when I did fosters I had two 9lb dogs once, then a 70lb dog, and then once a 10lb dog.
So it's always just been nice to have the bulk bag around. We keep it in our storage room, so it's not really in the way, and I've never had a dog refuse to eat as far as it not being fresh, but I always make sure it is either sealed or rolled and clipped and air pressed out as much as possible and time to time we put a li'l gravy on it depending on the dog.
Now that it's just Maci I may downgrade to the 10lb? bag. I don't think you can earn a free bag with the 2.5lb bags? Maybe you can? Our pet store in town doesn't sell Royal Canin and I am not in the city like...ever. Acana is more readily available I find especially in small towns because it is a "local" canadian made food. However I guess I see no problems with RC... it's just pricier, but still a good quality.
Now about this eye drainage... what is normal lol! |
