Welcome to DFA! It can be overwhelming, yes, but sometimes the best way to learn is just by trying some of the different ideas people post that appeal to you, see how it works with your dogs, and tweak the thing or choose something else.
I just posted the below info for someone else, lol, but it is altered to fit your questions. I am not a professional or anything, I can just tell you what I think and do:
I think that no single dog food is perfect, and different foods have varying amounts of protein, carbs, and fat, but Victor is a high-quality food and all the flavors within it seem pretty good to me. If you want, you can also rotate both within a brand (basically switch up the Victor flavors), or rotate the Victor brand with other good foods, like Dr. Timās, Earthborn Holistic, and Annamaet, among others ā this will offer your dogs a variety in the formulas, tastes, vitamins, etc. The kibble sizes in most of these foods are pretty viable for a Chihuahua to handle, but I am not sure about Dr. Timās ā the kibbles may be a bit big for a 4-lb dog.
If you choose to rotate brands, give it at least 10-14 days, adding a little bit of new food to the old at a time, and watching the stool ā if stool is good for 2 days or so, add more new food, take more old food out, and so on. If stool is not good, back down the amount of new food, up the old food. When they get used to rotating, you can switch brands with every big bag (what I do, but with small bags, lol). For now, you can switch to a brand, then exhaust most of the flavors within the brand just so they donāt have too many changes at once, then go to another brand. Also, you can add canned plain pumpkin to aid their digestion in the process, or a supplement called Perfect Form by The Honest Kitchen (THK). I swear up and down by it ā anytime my Bruno has an upset tummy, it tightens him back up in a snap! But donāt overuse the Perfect Form ā use it only as needed, and the amounts to feed are on the package, as well as on THKās website. Which leads me toā¦
ā¦ if feeding Perfect Form with kibble, you will need to add some water to it. It will look like a greenish soup of kibble, lol. But, with that said, extra moisture added to dry kibble is always good for the dog. You can add plain lukewarm water, yoghurt/kefir, coconut oil and water, or canned food (and water). Any mix of kibble and canned is fine as long as the dogās tummy is ok with it and as long as you adjust the amount you add and remove the appropriate amount of kibble so that the caloric intake stays about the same. So introduce the canned slowly, and not while transitioning between brands. You can also add dehydrated/freeze-dried/air-dried foods and water to kibble as toppers too, canned sardines (no salt added, in water only), fresh vegetables and meats, some fruits, and the above suggestions. Make sure you add NO onions or any grape products (grapes, raisins), some mushrooms.
For my 15-lb terrier mix I feed 1/4 cup of dry kibble twice/day, each time with some different topper from the ones mentioned above. I use coconut oil (twice/week), raw egg (once/week), The Honest Kitchen dehydrated foods (4 recipes, each one once/week), Big Dog Natural air-dried food (once/week), yoghurt/kefir (twice/week), 1/2 of a 3.5-oz can of sardines (once/week), 1/2 of a small can of dog food (right now either Weruva or Wellness, twice/week, no kibble at said meal), and a raw meaty bone once/week. All toppers minus the egg, sardines, can of dog food and the RMB I give a teaspoon of. And I add warm water to the mix in all meals. The dehydrated/air-dried foods kind of require it, lol. Bruno loves his āsoupsā (thatās what kibble and water and toppers look like) and he is slim, but muscular ā his body condition is great, his coat is great, and he loves meal time.
So you can implement some, all, or none of the suggestions, or tweak them to fit your dogsā needs. Good luck, keep us posted, and let us know if you have any more questions. š
