Natural Trainer Sensitive No Gluten Adult Medium/Maxi with pork - dog dry food

We bought this product for our shi tzu dog (who’s extremely allergic to almost everything). We were happy with it, but with our last order, the product’s composition changed somehow (there was no indication of this). The food itself now has a much stronger smell than before (it used to be completely natural), and unfortunately, our dog became terribly smelly because of it. Sadly, it’s not clear whether this is a manufacturing error or a permanent change, because if it’s the latter, we’ll have to look for another alternative, but our options are getting more limited.
