Just see what your vet recommends.
A prescription or bland diet, soft food instead of kibble may be a good idea.
Always have fresh water available 24/7.
You said you feed 30 minutes before you leave in the am, in my experience most dogs have a bowel movement about 1 to 3 hours after a meal.
If you could feed smaller meals and have someone come in mid day to let her out for a bathroom break it might help.
Those plastic automatic feeders are useless, most dogs are able to destroy them within 20 minutes.
