We ran into PetSmart to get a night time heating light for Ameila because she's been sleeping in weird places to try and keep warm, and when we went to check out they had bags of Wellness Core for 50% off at the register!! We got the ocean fish one. I checked it over for chicken or chicken fat, ect, and decided to go a head and buy it. For 8 bucks, you might as well, right? LOL So anyways, Bentley is about 3 months and 3 weeks, close to, if not already, 6 pounds. I was going to put him on Taste of the Wild (one of the two available here that was all life stages. Can't remember which two flavors they are ATM), but since I just bought this bag of Wellness Core, I won't do that just yet, I don't think. I'll see what you guys have to say So, my question is, is there a difference between adult foods and All Life Stages foods? I wouldn't really think so, but I'm not the food expert. I just know what to look for ingredient wise.
