Start small
A predictable meal routine can make everyday care easier to share between caregivers.
There is no need to rush. A predictable, manageable step is usually more useful than trying to solve the whole situation in one day.
Try this next
Use the food and portion guidance appropriate for your dog, keep fresh water available, and record changes worth discussing with a vet.
Notice what helps your dog stay comfortable and engaged, then repeat that version before making the situation harder.
Keep it kind and practical
Keep notes simple and current. For illness, injury, medication questions, or sudden changes in your dog, contact a veterinarian rather than relying on a general guide.
