To find a good veterinary opthamologist in your area, you can go to vmdb.org. Go to the CERF link and then into the ACVO Clinic List. There you can search by state for a Doctor near you.
People often complain about this in this breed because the tears will darken the fur.
Tears and saliva are both very acidic and that could be the reason that the fur is turning brown. There are a lot of different whiteners that you can buy over the counter. Your vet can probably recommend a good one but you probably benefit from checking with your groomer first. They deal with this problem on a daily basis so have a broader knowledge basis. If she is licking herself a lot, you may want to have her checked and see if allergies are a problem.
Another treatment for this is giving your dog bottled or distilled water instead of tap water. Many breeders of white colored dogs swear that 1/2 tablet of tums, 2 times daily works wonders OR teaspoon of white cider vinegar added to drinking water. (it supposedly changes the ph in the tears... yeah, right....) Check with your vet before trying this one because I have never used it myself.
Tetracycline is the drug of choice for this common tear problem with the breed and is readily available for an adult dog from your veterinarian, (it cannot be given to puppies or pregnant bitches as it will stain juvienile teeth). Let me know if you have more questions! Good luck!
Honestly, I find that most regular veterinarians are well equipped to handle tear duct problems. I only see the opthamologist if it's something that is out of their realm.
But most vets can handle a procedure like you're describing. The issue is really not the eye, it's with the ducts. So, vets are capable.
I would want to try the high dose antibiotics before I try the surgery, though. Just as a last resort.
I am sorry but I don't have any data on that. But I can tell you that you want to preserve those tear ducts if at all possible. They are necessary to lubricate the eye and without them your pet can end up with a condition called "dry eye." Dry eye results in blindness. It requires daily medication to lubricate the eye and it's pretty expensive. And, even then, many dogs just don't have enough lubrication for healthy eyes.
So, you definitely want to save those ducts.
I understand. You asked about the dog not having ducts. So, I wanted to explain about dry eye, which is the product of no ducts or blocked ducts.
You're correct. The antibiotics do not stop the tearing. So, your second task is to find out what's causing the tearing. In most dogs, it's allergies. These may be allergies to grass, pollen, cleaners, foods, etc. Your vet can perform allergy testing to tell you what she's specifically allergic to.
If the tearing is not a problem to you or her, you can live with it. But that's completely up to you.
Your question became much more than just "help me find an opthamologist." But you're still not required to accept my answer unless it is helpful to you.
You didn't tell me that you were in Texas. You just said you wanted to find one. So, I sent a directory.
