We currently have 3 corsos (11 mos and 5 mos brother/sister) with the intention of adding another in the future... None the less, I have been feeding Diamond large breed puppy to the younger 2 and Diamond sporting dog (high energy?) To the older female. The older girl seems to do pretty good on it but were on our 2nd bag of the puppy and while they're gaining weight, they never seem to have a solid bowel movement. Not watery, diarreah like but just not solid. More so soft ice cream like movements (sorry for the graphicness) so I'm curious what would be better to switch them too. I'm not opposed to switching them all to the same food as no food seems to impact the older girl. Any help would be appreciated.
