Tear Stains/Saliva Stains - One of the most common questions I get asked is how to get rid of tear stains. Daily washing this area will help get rid or it and regular grooming to remove the hair that gets stains will help. Their are also products such as Angel eyes that you add to the food to prevent it. Or you can change to a dog food that does not contain food dyes. Not only is tear staining unsightly it can really irritate your dogs skin and can make the hair mat under the eyes.
