My dog has a strange cauliflower-like growth on his gums. What is it?

Thank you for the picture of the growth in Tucker's mouth, it's really helpful. That appears to be an oral papilloma, which are small, benign tumors of the mouth caused by the papilloma virus. These usually affect dogs under two years of age, and are transmitted from other dogs by direct contact, such as eating and drinking out of the same water bowl or greeting each other. Since canine oral papillomas are usually asymptomatic, treatment is often not indicated unless they become infected or become symptomatic. Infected papillomas require a course of antibiotics, and if a dog ends up having a lot of oral papillomas in their mouth, they can be surgically excised or treated with cryotherapy (freezing). I do recommend having him checked out by a vet for this to make sure it is an oral papilloma, as I cannot make a definitive diagnosis without seeing him person, so give his vet a call to make him an appointment. I hope this helps!

It appears to be a papilloma, or wart. These are typically benign growths that resolve on their own in weeks to months. You would need to have Sharon physically examined by your veterinarian for confirmation. Surgical removal is an option, but does not guarantee another will not grow in the same spot or a different one.

While odds are good that Monty's lesion is likely a viral papilloma, the only definitive way to determine what's causing the lesion is through removal and biopsy. Viral papillomas are most common in young dogs (like Monty), as well as those that are immunosuppressed. While viral papillomas are contagious between dogs, in young dogs they typically resolve without treatment. That said, some do dramatically worsen or become infected, which is a bit more complicated to manage. Topical treatment won't do any good, particularly for any lesion in the mouth. It would be best to have this lesion evaluated by your vet, who may recommend diagnostic testing to confirm their diagnosis. With that said, it's also not wrong to continue monitoring it to see if more lesions develop or if this one changes at all before pursuing further investigation. Until you know for sure what is causing this lesion, keep Monty away from other dogs at doggy daycares, dog parks, or kennels. I hope that everything goes well!

Indeed it looks like oral papilloma, fortunately this is a benign tumor that in most cases resolve without treatment within several months. There is a specific antibiotic called zithromax that is believed to speed up the healing process, you can ask your vet to prescribe it for her.

This looks like a growth of some sorts, like an oral papilloma. These are benign tumors of the mouth, lips, and gums. I would have Dakota seen by a vet for it. The vet can confirm if it is an oral papilloma, and can discuss methods to remove it if necessary. Best of luck.

This looks like an epulis, a fairly common benign tumor in dogs. It occurs more often in short faced dog breeds. I recommend getting it checked by your vet to determine what kind of growth it is and what needs to be done about it. Your vet will do an exam, lab work, possibly imaging depending on if you vet believes they need it. Based on these results your vet will be better able to tell you what is going on and the best course of treatment.

These look like juvenile warts (oral papilloma). Such warts are caused by a virus, they are self-limiting and and will go away by themselves eventually within a few months. They will need veterinary attention if they increase significantly in size or amount or start bleeding, get infected, or cause other problems.
