Hello! I am planning on switching our Ruby (just turned 4 months) to an better quality kibble. I have been trying to research (reading other threads, looking at various manufacturer's websites) and think I have it narrowed down to Merrick or Wellness. (I can buy either of these at several different locations without much hassle.) I can't decide which one to go with. I realize that all dogs are different and some react differently to foods than others, but is one more recommended than the other for puppies? Is one richer than the other, in general? Also, as far as these two brands go, is it recommended to go with the adult or the puppy formula at this point? Should I start her on the puppy with the smaller kibbles (I am assuming the puppy is smaller) until she gets more adult teeth in? We generally add a small amount of boiled ground chicken or beef, brown rice, chopped veggies, and a dollop of yogurt to her kibble, so it's a bit more moist anyway (it was the only way to get her to really eat well), but I was just wondering if the adult size kibble would be hard for her to chew with such tiny little teeth. Anyway, just looking for a general consensus here to help in my decision making process. Any input will be much appreciated! Thanx!
