What my dad did was buy 2 pails, & would divide a 50 pound bag into both of them. RB Max ate Nutro Senior & there was only a few days worth that couldn't fit in the pails.

We kept the pails ontop of eachother in the kitchen & we only opened 1 at a time. & we kept the lid snapped on tight all day long.

the bigger bags r MUCH cheaper, so go buy some big strong pails & they'll do the trick
