Heather answered 4/15/2008 My Dog Has Red Sore Patches All Over Her Stomach, Her Legs And Under Joints. It Makes Her Really Itchy,she Has No Fleas. What Might Be The Problem? Benedryl, cheap and effective. Worked over night on my great danes belly rash. Its 100% safe look it up online or call a vet and ask. 1mg to 1lb of body weight if its the pill, I prefer the creme.
