I am reluctantly replying because I sense you are really distressed and could use a few simple suggestions. I am making these purely non-professional suggestions going on these statements in the post: You annually take your pets to vet. Your vet has not found a reason for the dog’s accidents/soft stools. You spent all you had on a pet you loved who sadly, you lost. I am very sorry.
Assuming you will at least be going back for rabies this year, I would consider doing some investigation in the meantime. Keep notes. Does your dog get into stuff you don’t know about? Eat his own or other animals feces? Drink enough water? How much? How often? Does he gobble his food? How often does he poop? Particular times of day?
Perhaps gating him to an easy clean area, when you are not around, would be useful. Taking him for walks at times he seems to naturally need to go out. If he is not on a sensitive food diet, slowly get him on it and give him plenty of time to adjust. Is something causing him stress? Does he hate his crate?
When you schedule that annual, (you will obviously need a rabies at some point this year) take all of your findings with you and try to get a fecal exam done at that time. Probably about $30 or so extra dollars, but you will only have the 1 exam fee then. If there is another vet in that office, see if you can get a second opinion from that one. Or switch entirely. Of course, if things get worse, you will need to do something sooner. But you knew that.
Good luck. I know everyone here, including you, believes vet care is important. I’m sorry you are struggling right now.
