Hello. Thanks for writing in. My name is***** and I would be happy to help you. I am not set up to do phone calls but would be happy to answer any questions you do have online. That brownish/reddish color that forms on the hair is due to the enzymes in the saliva. It is common to see in white haired breeds (I am assuming she is has a white hair coat). You often see it around the eyes because the enzymes in the tears do the same thing. Many of these breed, including Maltese and Poodles, tend to over tear, so you will see it often there. Some may have a little excessive salivation, but there could still be a medical reason behind it. In many cases, their teeth and gums are not in the best condition. If she has chronic issues with vomiting, diarrhea or lack of appetite; it may be related to nausea. Either way, I would have your vet do a full oral exam on her. The licking of the paws may be due to an allergy or it could be an OCD thing with some dogs. But, if the paws are white, they will often turn brown as well. Your vet can evaluate her for a potential allergy. Unfortunately, there isn't anything good that eliminates the brown color. If related to the eyes, Angel Eyes may help. A topical antibiotic for the eyes, called Terramycin, can also help. It is harder to control around the mouth. I have recommended giving a teaspoon of plain yogurt daily (actually heard that from a groomer friend of mine, and it has worked in some cases) to eliminate the color change. I have had mixed results with that, and it has even given some dogs a bad upset stomach. She may just need a teeth cleaning by your vet at this point. Please let me know if you have any other questions or concerns. Hope this helps.
