I used the Kirkland brand for a couple of years with my two. It seems to be a decent quality compared to others. When the whole contamination issue started, I switched them over to Wellness. The only change I have seen is they have MUCH less "houndie" smell to them. I used to have to bathe them every two weeks because of their smell. :blink: Now I can go up to 4 or 5 weeks and have to bathe them because they're dirty.
