Enema Procedure
When administering a dog enema, start with two to three tablespoons of warm water for small breeds, and about one pint of warm water for medium to large breeds. The water should be warm, but not hot. Add to this water a few drops of lemon juice, a few grains of sea salt, and a pinch of potassium chloride; these electrolytes help restore your dog's fluid balance. If you are administering the enema to treat constipation, these additives won't be necessary.
