jewlz,
I highly recommend the membership to Costco, on its own merits, but not dog foods. On that note, Costco guarantees that you recoup your $50 membership within 6 months plus savings, and will allow you to cancel with refund and keep merchandise if you do not or are unhappy. Ask.
I’m a huge fan of Costco, but this is not one of their stronger merchandise sections. And be wary of the treats too; they often (not always exclusively) have China made stuff. I don’t recommend the Kirkland/Nature’s Domain foods because they are Diamond manufactured, which I believe makes them overly risky, and to get those low prices they cheapen & take short cuts on many of the ingredients and overall formulations you see, such that they are not really comparable to some higher quality foods.
I know little about Boxers & Bulldogs, really not my breeds, but enough to caution PLEASE be careful about whatever nutritional and life care precautions necessary re: dilated cardiomyopathy in which available taurine and carnitine factor and bone issues from extremely high breed incidence of hip dysplasia (Bulldogs; see OFA stats) to cruciate ligature and bone wear & tear stress w/Boxers.
