Assuming she’s had a fecal done and wormed if necessary, I would consider adding a probiotic and/or enzymes to help her gut re-adjust and settle down a bit.
One of mine would go 4-5 times a day as a puppy, but as an adult he’s a once-a-day’er.
How much are you feeding and how many times a day? Sometimes the instructions on the bag are a bit on the high side (or, WAY on the high side) which will result in a lot of poop and a fat dog in a few months time. If she’s inhaling her food, it might be going right through her. A puzzle toy might help (buster cube, etc). Most dogs love these, and most puppies easily figure it out of you move the toy a bit, let them see that movement = food appears. Plus, it’s fun to watch them!
