A little fiber everyday won't hurt. But, what would concern me more is - why are her stools loose to begin with? I think you first need to figure that out. Pumpkin is fine to be used a fiber supplement - but I wouldn't use daily to solve a daily stool problem.
So, if you're having an ongoing stool problem - I'd keep her off the pumpkin - and solve that problem first. Bc, it very well could be the chicken - as it was for my Marcel (amongst other things). Once you figure out the cause, if you still want fiber in the diet as a supplement - then add back in.
