Ask a Dog Vet and Get Answers to Your Dog Health Questions
My dog's gums turned black. She is drinking a lot more water as well. She has been on antibiotics for a while for a bacteria in her bladder that would not leave her. Her last culture showed the bacteria was gone. What could this be?
I need to ask you a few questions to be well informed and give you the best advice.
1- Did you have a chance to look at her gums before and they were not black, right?2- Any other symptoms?
Not like this. It looks like someone painted them black. She was licking her paws a lot, I checked them to see if there was something there. I found nothing so I decided to look into her mouth. Her gums have never looked like this before. She is also drinking a lot more water than usual.
Black color gums can be normal pigment but when it changes from pink to black it could be a sign of poor oxygenation which is a major concern as it could be as a result of heart or lung disease, red blood cell disorders, etc. When a dog drinks more water than usual it is a sign of either an active infection, hormonal disorders (diabetes, cushing's), kidney or liver disease and even cancer to name a few causes. To determine which of the above is the underlying cause, your family veterinarian will need to do some blood work (chemistry profile, T4 & CBC), x-rays and urinalysis as initial screening test. Unfortunately, there is nothing I can recommend for you to try at home in this case. Treatment will be based on clinical and diagnostic findings. I would highly recommend you have her checked by a veterinarian as soon as possible. Hope the above helps, if you have additional questions I will be glad to answer them.
