Hi Amelia-
Boy, can I feel your frustration. I have two golden labs that had/have similar issues. They are now four years old. I switched foods several times only to finally find out that they had parasites, both giardiasis and coccidia. Have you had fecal tests done to rule out both parasites and/or worms? Sometimes they are hard to detect and need to test a couple of times. After four or five treatments to rid of the pesky bugs, they were left with bad digestive issues. A lot of loose stools and also the walking around and dropping soft plops a little at a time like you described.
I turned to http://www.dogaware.com for a lot of great information on digestive disorders and diarrhea along with recommendations from several on this site. Pumpkin did not work for my dogs either. The Honest Kitchen’s Perfect Form worked great until my difficult dog decided he didn’t like the smell of it anymore. I also used and rotated Gastriplex made by Thorne, Vetri Pro BD by Vetri Science, and Phytomucil with success. I have fed Victor which contains clay that I think is beneficial with success. Now, I have been slowly weaning them off supplements and am feeding Whole Earth Farms with only probiotics now and then and they have for the first time have consistently firm poops!
It took a while for their tummies to heal, but it finally happened! You also might want to try feeding a little less food. Sometimes over feeding can cause loose stools as well.
Good luck! Please write back with any questions.
