Do you know why you aren't getting any answers to your question? It's because this post was IMPOSSIBLE to read. The only thing I got out of this was that you changed to a crap dog food, the dog had seizures, had a high sodium level and the dog was put down. Try posting this again in a way that someone can actually read something besides the dog food content.

Mislatru...How awful to have had to go through this!But...both dog foods you were feeding are HORRIBLE! You do need to know that! To explain:Purina Little Bites Dry Dog Food - The first five ingredients (and beyond) alone contain known allergens and garbage product for dogs -- little or big! Whole grain corn, meat and bone meal, corn gluten meal, soybean meal, animal fat preserved with mixed-tocopherols...whole grain wheat...brewers rice...Kibbles 'n Bits® Small Breed - The first eight ingredients alone contain known allergens and poor quality ingredients!Corn, soybean meal, beef and bone meal, ground wheat flour, animal fat (BHA used as a preservative), chicken by-product meal, corn syrup, wheat middlings...PROPYLENE GLYCOL!!!!!!! ARE YOU KIDDING ME????...pyridoxine hydrochloridePyridoxine hydrochloride, more commonly known as vitamin B6, is a water-soluble dietary supplement used to treat pyridoxine deficiencies CAUSED BY A POOR DIET, metabolism problems and drug use. Taking the supplement could result in mild side effects, and anyone planning to start a pyridoxine hydrochloride supplement should consult with their health care professional.Why should any such "additive" be needed to address "poor diet" in a dog? Possibly because the ingredients they have combined into their food is the cause of such a deficiency!Things to seriously avoid at all costs:Corn and corn glutenWheatSoyFiller grains (partial grains...cracked barley, brewer's rice, etc.)Undislosed animal fats (they should be defined...like chicken fat, etc.)Meat and bone meal (rendered products)Beet Pulp (rendered products)By-products of ANY KIND...ANYWHEREHeavy chemical additives -- these things are used to "preserve product freshness" -- in other words to protect the "shelf life" of the product...not the health of your dog -- look for natural preservativesHoney...you need to learn quickly how to read what ingredient labels tell you -- how to understand them and what to look for for the immediate and long-term health of your dogs!http://www.dog-food-aid.com/index.htmlhttp://www.dog-food-aid.com/dog-food-ingredients.htmlhttp://www.dogfoodscoop.com/dog-food-comparison.html
