we are on the best brand we can get
i also had that problem when layla was on Purina... that's what the breeder fed her.. and all was well... i think i'll have to try cutting out her wet food in the morning.. which she waits for.. but i'll try phasing it out... the vet had her on metamucil.. but that just made it worse.. which i figured since it is for constipation.. not our problem!
