Why is my dog's mouth spot changing color and what should I do?

This presentation could be due to a trauma or localized spot of skin infection (likely to be caused by bacteria). A check up, appropriate disinfection and possibly antibiotics (oral, topical or in a shampoo formulation) are needed to solve the problem. Disinfection may be started at home with very diluted hibiscrub or betadine or salted water baths. Buster collar may be useful as well to avoid any scratching.

Any topical product you apply will promptly be licked off. This could be localized infection or inflammation. An allergic reaction or mass cannot be ruled out by image alone. Legally, we are prohibited from telling to medicate the spot in the absence of a physical exam. Ideally, Lana should be physically examined by your veterinarian for a firm diagnosis. She may need systemic treatment as opposed to topical. In the meantime, place an e-collar (cone) on her to prevent pawing or rubbing. Keep the area as clean and dry as possible. Wipe her mouth after she drinks or eats.

Thank you for submitting your question regarding Lucy. She may have a mild skin infection around her muzzle. If she has had any new treats or dog food she may be reacting to the diet change. This will be more common if she is experiencing irritated skin around her anus as well or if she has had any vomiting or diarrhea. If not, check her eyelid margins, ears and footpads for any lesions. These are commonly affected areas for autoimmune skin disease. If her skin does not heal or spreads, she will need to see her veterinarian. In the meantime, keep her muzzle clean and dry. I hope this information helps!

Hello and welcome to Petco Pet Education Center, formerly Petcoach. Discoloration around the mouth can be due to saliva staining. If Brownie has bad teeth, then she might drool more on that side causing more saliva staining. I recommend you have her seen by your vet to check if there is a wound present under the fur, or if she has dental disease that requires fixing. Best of luck with Brownie!

Hi there and thank you for using Petco Pet Education Center, formerly Petcoach to address your concern. Without seeing a picture of what you are describing it is difficult to say for sure what this could be. I suspect, due to Blue's age, that this could be a viral papilloma, histiocytoma or pimple-like growth. In all 3 cases, it should resolve on its own. It could be something other than these 3 possibilities. If the spot does not resolve or it worsens, I would recommend having a veterinarian examine Blue to that the most appropriate diagnostic and treatment recommendations can be made. I hope this helps guide you in the right direction! Please let me know if you have any other questions or concerns and I would be more than happy to help you further.

Hello. Without a clear picture, it is impossible to assess what might be the problem. Since cleaning the area has not helped ( have you been using a mild skin cleanser such as one with chlorhexidine? ), this might be some kind of allergic irritation. These can especially show up if the feed &/or water bowels are made of any type of plastic. Always use stainless steel or ceramic dishes. If this does not seem to be the case, then the best thing is to have your veterinarian take a good look at the skin. Your vet can assess the area, do some rather simple skin scrapes or hair analysis to see if this is an allergic, inflammatory or infectious process. Good luck & thanks for using Petco Pet Education Center, formerly Petcoach.
