Vary brand and type of premade for puppy?
I finally got my puppy home yesterday, and her breeder fed her a mix of a specific kibble and mush vaisto ice blue. When I got her home, I switched to mush vaisto light purple because of availability close to me (and because you guys said it would be eaiser to feed premade raw compared to homemade when I asked about feeding requirements for puppies a few weeks ago). There's no signs that she struggled with the change. I'll do about 70/30 raw/kibble until the kibble bag is empty, but I'm wondering if I should stick to that specific raw brand and type throughout puppyhood, or if it would be alright to change between brands as long as they're balanced for puppies?
The kibble industry is very much "no variation, change is bad," which is obviously not right, but how much variation is good, and can there be too much? To me, it seems that varying brands and proteins will make the puppy's gut more robust and healthier, but how often should I rotate proteins and/or brands? She's a standard poodle, so she's got a fair bit of growing left.
I'm also curious what the difference between raw for active/working dogs and puppies is, as I've seen some brands have premade marked for both puppies and active adult dogs. It would obviously depend on the brand, but since she'll probably be growing until she's past one year old, and most places recommend sticking to puppy food until then, would it be possible to add active adult dog food into the rotation when she's getting close to the one year mark?
(I'll post a photo of her in the comments because I might be biased, but she's an unfairly cute puppy)
