Just got a bag of this today...Took the recalled bag of TOTW back that was half full and the petstore gave me store credit for the full amount of the bag...Got a 30lb bag of the Earthborn to try for a bit while Diamond gets their stuff together for a bit.
I dunno about making kibble lasting...honestly, if you gota purebred boxer, man the cost of the kibble is gonna be the least of your concerns in the long run....I try to feed my 18 month old dog almost 4 cups a day and hes still really thin...I sometimes will add in certain things that I am eating like burger, fish, venison, ect3 (all unseasoned)...I tried chicken but it dont agree with him...
Wet food I add sometimes at dinner, however the good stuff is not cheap either...
