UPDATE
We are on our second bag of Earthborn Coastal Catch. 1 & 1/4 cups twice per day. Raine is 50-ish pounds (haven't weighed her in a while but that seems about right).
FINALLY.....her stool is better. Probably the best and most consistent since bringing her home at nearly 9 weeks of age. She turned 2 July 1st. For sure the best it has been since I started the transition (and various foods) months ago. This has been a LONG process. Even during the first bag of this food only I was still wondering if it would work.
Ran out of yogurt a couple of weeks ago which she has always eaten after dinner (about a tablespoon) and kept forgetting to get some more. That is when I started to notice her stool was firming up. I do not know if the yogurt contributed to the issues or if was just a coincidence with finally being on one food for a longer stretch of time and getting the feeding amount correct. At this point I don't want to add the yogurt back into the mix for fear it was adding to the problem. She has been given ricotta cheese in the interim, although not as frequent as the yogurt with no issues. I don't suspect she has a problem with dairy so much as she has a problem with how much DH gives her. I give the ricotta at various times and not with meals so I can control how much she gets.
Obnoxious gas is no longer an issue either. That is a huge plus.

I'm sure she feels better and I know my house is a more pleasant place to be. She still has gas on occasion but not easily noticeable as it should be!
Had an occurrence of vomiting white foam yesterday morning before breakfast but nothing to be concerned about. She ate normally right after. Don't know what that was about. She had her normal two biscuits before bedtime and two as soon as she woke up. Just a fluke I suppose.
Been eating the heck out of the garden tomatoes, zucchini and lettuce (we give her). She loves her veggies.
She seems a bit thinner to me so I might consider adding another 1/4 cup or so as treats in the afternoon but need to weigh her first to confirm.
I hope this is the end of her stool issues if not forever at least for a long time! For those going through a transition.....don't give up! The right food is out there. If I who have little to zero patience can get through this so can others!!
