Vitamin B tablets will not cause any harm, but I would not expect them to help heal sores or boils in the mouth either. It's quite unusual for dogs to get a sore or boil like this under the tongue, so I would definitely want to find out what is causing the problem first - it could be a wound, a bacterial infection, or even a tumor of some kind. Treatment will depend on what the underlying problem is, so it's important to get a diagnosis in order to know what treatments might be helpful. I would recommend taking Bruno to the vet for an exam - your vet can do some additional testing if needed to help determine what is causing the sore and get him started on appropriate medication to treat it.

My dog has a tongue blister. Are vitamins safe and effective?

Without knowing the cause of the blister on your dogs tongue, it is difficult to determine if a vitamin tablet will help. If the blister persists than your vet may need to do a biopsy to diagnose the problem and determine the best treatment. If the blister is caused by a viral infection than it should resolve within 7-10 days.A vitamin that is formulated for dogs is safe to use.

My dog has painful mouth sores after grooming. Why won't they heal?

Thank you for submitting your question regarding Bobo. I recommend that he sees his veterinarian if his mouth is not healing. It is odd that a groomer could cause such significant wounds from brushing his teeth. I worry that there is an underlying disease present making his mouth more sensitive. For example, his breed is prone to dental diease. If his gums are sensitive due to gingivitis, this can make them bleed. Based on his exam findings, his veterinarian will make treatment recommendations. He may need to go under anesthesia to have his teeth cleaned. I hope this information helps!

My dog has red bumps on his lips and mouth. How can I help him?

Poor guy! Your can try this: It won’t hurt him if he licks it off. However, if it’s not improving in 5 days or so, I would recommend that you schedule a recheck with your vet. I’m worried he may need antibiotics, as he may have a deep skin infection. If it continues to be a problem , a skin biopsy may be recommended. Thanks for asking PetCoach!

My dog has a red sore on mouth roof near throat. What should I do?

I am sorry to hear about Duke. If he is eating normally I would monitor the sore daily. It is possible if he is a chewer of sticks and things he could have traumatized the roof of his mouth leading to this sore. If the sore is not getting smaller in a few days or more sores appear, the sore appears raised like a mass, he has decreased appetite or energy level, then a vet exam is recommended.

Why does my dog have blisters or sores around his mouth?

It could be local infection or allergic reaction. Have Mylo examined by your veterinarian to diagnose and treat infection. If Mylo eats or drinks from a plastic bowl, switch to ceramic or stainless steel to see if that makes a difference. Some dogs can be allergic to plastic bowls.

As long as it does not seem to be worsening and he is still happy and not showing any signs of pain the sore should heal over the next few days. however, if by chance it is not gutting better on its own, veterinary attention ay be needed

My dog has fever, no appetite, low blood cells, and mouth sores. What's wrong?

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Poor Luana! I have seen viruses attack the oral mucosa and also hit the bone marrow causing low white and red blood cells. The ulcers could also be from electric chord chewing or licking something caustic. Other possibilities are cancer and immune mediated. If it is a virus her blood values should improve over several days. I would have her hospitalized on IV fluids and IV antibiotics, oral sucralfate for the ulcers and an oral chlorhexidine rinse. She should also be on pain medications. She should have CBC's to check the progression of her white count at least every other day. I wish you both the best!
