It is great to research & learn about ingredients. Sometimes I get a headache from searching for long periods of time, but my girls are worth it

lol
Over many years, in the past, I have used Eukanuba without realizing how the main company operated & how low the quality of ingredients was, as well as Science Diet & Purina brands. Once you start researching, you'll know which foods are really crap!!
I have experienced recently that some brands often change the mill where they make their food & by doing this, their ingredients/quality changes. I was using Timber Wolf & this has happened with them. Some places here in Vegas have stopped carrying their food because T.W. is not up front with what is happening.
I have researched & looked, and am in process of changing the girls food. I doubt I will ever stop researching.......
