Hi Caitlin-
You do already have a lot of things going on with your dog. But, if you decide to use a probiotic, you need to give it a few hours after or before you give her the antibiotics because they will just cancel out the benefits of the probiotics anyway. Also you might want to add some plain canned pumpkin to her meals. Many people have success with pumpkin relieving loose stools.
Two of the three canned foods you mentioned, contain carrageenan. My dogs seem to be sensitive to that ingredient. I usually try to stick to stews to avoid it. But, I do see that you mentioned that your dog can’t chew anything so maybe you could smash it up a bit if they work better for your pup. Hopefully it is just from all the meds she is on and will be back to normal in the next few weeks. Good luck!
