Josera Medi/Maxi Adult Chicken & Rice - dog dry food

I fed Josera for years, both my dog and I were always happy with it. My dog just can't tolerate this food at all, he got really bad diarrhoea. Such a shame, for my dog and for the money. Now I have to switch brands after all. The packaging used to be better too, it was paper with a zip. Now it's plastic and you have to cut it open at the top.
