I will look for the Purina Salmon and give that a try. Thanks for the suggestion on charting her health, I hadn't thought of that. Will try to pick up a calendar/planner this weekend and get that started. My memory is spotty and out of sequence when I try to recall her troubles.
If she is not having a stomach episode then she will not eat the grass but very minimal. When she is having stomach/diarrhea problems then she will seek the tender grasses and graze like a cow. At this point, starting about a month ago, I will give her canned pumpkin. It seems to have an immediate improving effect. She also does not seem to eat grass as long as I feed her pumpkin but I don't want to feed her pumpkin continuously, I'm not sure if that is good for her long term. I normally give her two table spoons of pumpkin mixed with a smaller portion of kibble.
I haven't even been to bed now for 24 hrs, just got back from the grocery store where I picked up 3 more cans of pumpkin and fed her two large spoon fulls of straight pumpkin with no kibble a short time ago. Will probably end up crashing soon but wanted to start getting advice as soon as possible. Thanks everyone.
