Hmmm, vinegar eh? I have tried the "cornstarch + hydrogen pyroxide", and it worked well, but only for a bulldog who did not have allergies. If they have runny eyes all the time there is probably no way to get rid of the staining, which is ok too since almost all bulldogs have tear stains.
For those of you that don't have a problem with this, TELL US YOUR SECRET!!!!
Also, clean the wrinkles and face daily with a warm, clean washcloth or baby wipes work good too.
Inside wrinkles I have heard of --and tried ---baby powder. This helps dry it out if you have too much moisture and inflammation. Of course, then you have to clean out the dried up chunks of powder.
Also a new one I have yet to try, recommended by two people, is generic brand acne pads. (only if the wrinkled area is NOT inflamed!!!!)
Another has told me recently to look into "angel eyes", curious if anyone has tried that and if it works?
