Tough situation with my female boxer?

[Rob]

I have a female boxer 1.5 years old. May of last year, she had an en-strangulated colon, and a big portion of her large intestines was removed. She has always had digestive issues, but since the operation, is has been very hard for her to gain weight. The issue is if I feed her to much, she has diarrhea, and if I don't feed her enough, she's not gaining weight. She has always been fed high premium food (Canine Caviar), until recently. Canine Caviar decided to use dark meat chicken and it's been giving her diarrhea. I switched to Solid Gold "Barking at the moon", and it's been one week, and she still is having diarrhea. I just realized that Baring over the moon is a high protein, low carb dry food which is not what she needs to gain weight. I have to soften her dry food or else she gets diarrhea. I can't seem to find the right combo to get her to gain weight & curb the diarrhea. My girl looks sickly, but energetic and playful. I have tried Canidea, Evo, Prescription I/D, Wellness, etc. I don't know what else to do. I feed her 1 cup, wait an hour, and then feed her a second cup Morning / Night (total of 4 cups per day). Since she has digestive issues, I figured to not shock her system with 2 cups all at once with each feeding.

Things she never could digest: Rice (goes right through her), Hard dry food, hard carrots, basically anything hard.

I have spoken to my vet and he's basically out of answers. I want my girl to gain weight, but I can't seem to find the right food for her that will stop the diarrhea, and have her gain weight.

Really need help here, please! I love her so much, and she has been though such a rough puppy hood.

that was a good answer, you can also give her some nutri-cal which will stimulate her appetite
