Which NB Formulas are you all using?????
If I can find out any info I will post it. My guess also is it was when all the recalls were going on. Now NB seems to have a better handle on things.
If you are worried about your bag you can enter the numbers off the bag at their site and see the tests they did on that batch.
I tried to feed Max NB Ultra but he did not like it.
He is eatting Wellness Small Breed and LOVES it.
I got tired of all the warnings (true or not) about the high protein in EVO.
