You can add some gravy to your dog’s dry food to enhance the texture for better chewing provided it is free from spices, salt, and onions.
Chicken broth sauce or bone broth without spices and salt can be added to enhance the nutritional value.
However, gravy with high sodium and fat content will have a very bad effect on your dog’s health potentially causing vomiting, diarrhea, convulsions, and may end up in kidney failure.
