Vianca, I am not a pro, but from what I know, different breed puppies mature differently – a small or toy breed puppy can be considered an adult and fully-mature at 6 months of age; large and giant breed puppies can continue growing and be considered puppies for up to 2 years! So I don’t know where the 5-month mark came from. I do know that adult dogs just don’t need the extra calories from puppy food, that is why the amount should be reduced, but as with every dog, you need to watch activity levels and overall body condition and adjust accordingly – for example, reduce food if she’s getting chunky or is in general not very active, and increase food if she’s too thin and/or very active. As for the dog being spayed, I don’t know if you have to reduce her food, maybe one of the pros here will jump in on that part. For my Bruno, I only reduced his kibble 1/4 cup from his 1 cup/day allowance after being neutered, but that coincided with him being 6 months old and an “adult” now. Also, now I complement the loss of kibble with various toppers (wish I did that when he was a puppy, but oh well, he got his fair share of bully sticks, fish skins, etc.), so he hasn’t really lost the calories, but he burns them just fine.
My Bruno is 13.5lbs and he’s at moderately high activity level. He is supposed to get 1 cup at most of food, I think, for his weight group. I feed him 3/4 (heaping) cup of dry food plus The Honest Kitchen as a topper and coconut oil/yoghurt every other breakfast, and a raw egg, canned sardines, and a raw meaty bone once/week for each. He is lean, muscular, and in good body condition.
I wouldn’t worry too much about the actual amount – just observe your dog and adjust accordingly, and eventually you will find an amount that works for her.
