Hello there, it’s Sydneyru the dog here.
Hot Spots on your dog? Try the formula; Mix 10 drops of GFX (grapefruit Extract) per each oz. of water. Tap or distilled water is fine. Put this mixture in a spray bottle and apply two or three times a day until it goes away. IF the spot becomes covered in a yellow pus you may have waited to long, but I have even had good results with these kind of hot spots. Keeping it clean and perhaps cutting the hair away to help it dry is a good idea but not always necessary. Years ago German shepherd breeders used a mild form of bleach and water which as OK but not near as good a s the GFX.
