Brit Care Dog Sustainable Sensitive Fish & Insects - dog dry food

It used to be the perfect dog food. A few months ago, its colour changed and became lighter. At first, there was no problem. But in the past few months, my dog has been scratching noticeably more. There’s no actual inflammation or hair loss, but the scratching has increased a lot, and for me, the two things seem to be connected in time. Maybe it’s since the food became insect protein-based. I’m not sure. It’s a shame, because it worked really well for years. Now I don’t know what to switch to.
