Where is the rawhide from? Some is processed in China...a scary thought. The way rawhide is dried may contain chemicals. But I doubt thats the reason for itchy's.
I think he may be scratching due to the dry air of Winter. Do you run a humidifier in the house if you run a furnace? Most dogs are getting the winter coat in right now so are on the itchy side while it comes in/add in the dry temps and it seems all are scratching. Are you supplementing with oils, and feeding a good kibble?
I wouldn't allow any rawhide bones whatsoever! They can cause obstructions after they're swallowed and the dog drinks, poof! And onyx'girl brings up another good point- nothing from China. I know that's limiting your options but I just wouldn't risk it, the chemicals that are used in processing can be deadly. There are many reasons your dog could be itching- a food allergy would be the first guess. Are you feeding a grain-free food?
yea , young my dog was on purina . i changed for orijen puppy formula ( large breed ) but finaly found out both had chicken in it and i was suspecting a chicken allergy since he was scratching way more since he was eating orijen . so i changed to six fish formula ... hes on it since 2 week , but still scratching , and bitting himself on the back / paws . but eyes/ears/lips seems ok ... i dont know maybe cause its dry and winter coat comming in ... i might change to Nutro allergic formula if he keeps scratching hardcore .. Nutro is good food ?
I would keep him on the fish based for awhile longer. Allergies take time to get out of the system if it was food based.
Instead of Nutro(I don't think it is a good food) Natural Balance limited ingredient would be a good choice or a fish based(which you are already feeding) if you think there is a chicken allergy. Make sure you look at the ingredient list to be sure no chicken is included.
Benedryl takes the edge off as well. Dosage is 1mg for every # the dog weighs.
