Hi Patricia,
When purchasing kibble for my own pets, I want something that is no longer than 6 months post production date. My 6 month rule isn’t written in stone and that number is based on absolutely nothing other than my own personal preference. Often times what I’m buying is ~2- 3months post production date but once the bag was a mere 10 days post production date!
Natural preservatives simply are not going to have the anti oxidant potential as synthetics and since consumer demand is for natural preservatives that is the way a lot of products are produced. Storge conditions in the manufacturer warehouse and distribution center and pet store can impact how well the preservatives “hold”. I suspect under adverse storage they may not hold up for full 12-18 months so I’m hedging my bet by using shorter cut off. But this is all conjecture on my part.
Interesting that Stella and Chewy’s states an expiration of 14-18 months post production in their FAQ and the bag is dated out 5 years. Have you contacted them for an explanation? You might want to inquire if they have held the food under adverse conditions such as high heat and humidity for 5 years and then tested it to ensure excessive oxidation did not occur
While in the FAQ section, the question on feeding large breed puppies caught my eye. Their answer makes no sense to me. They write:” Things are more limited with our kibble, as you would need to stick with the puppy-specific kibble recipe (calcium and DHA levels arenât enough for large breed puppies in non-puppy formulas)”
It seems to me they are saying there is not enough calcium or DHA in their diets that are labeled as formulated for all life stages except the growth of large breed puppies. AAFCO’s min for Ca and DHA are the same for ALL puppies. AAFCO’s profile does not require more Ca for large breed growth. The AAFCO profile places a LIMIT on how much Ca can be in a diet for large breed puppies. Diets that are labeled for growth except large breeds can only mean that the calcium level in the food EXCEEDS the maximum NOT that there is not enough calcium in the food for a large breed puppy. I’d find it very disturbing if they didn’t understand this basic nutritional concept.
