My dog has bumps or flaps on her lip. Are they normal or serious?

It's still a little hard to see these things well, but I did not say they look normal. They could be thickening from chronic inflammation, something like a wart or something more worrisome. A vet should take a look at those and check then further.

No need to worry too much yet. In such a young dog it is highly improbable that anything too terrible is wrong. In all honestly, it is very hard to make a diagnosis of dermatologic issues without actually feel the lesion, and / or collecting some diagnostic samples. At first glance, they look like eosinophilic plaques (otherwise known as rodent ulcers), which are actually much more commonly seen in cats. Since you are seeing these lesions on both sides of the mouth, it's also possible that this is something anomalous but normal in your dog. Another possibility is that your pup could have bit onto something that cause some irritation, and it is now causing something wrong symmetrically. If the areas aren't getting large and are not bothering your dog, my advise would be to leave things alone for the time being to see if there is any change. However, it wouldn't be wrong to take your dog to the vet now to have him checked over. Hope this makes sense!

Thanks for using Petco Pet Education Center, formerly Petcoach! This could be a benign or malignant growth. There is no way of knowing for sure without an examination though this represents a reason to seek veterinary care. This is usually determined with an examination and a fine needle aspirate (FNA) or a biopsy. Treatment depends on the findings up to that point. I recommend you have Panda evaluated by a veterinarian for further assessment and treatment. Good luck and have a good day!

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.

It's not normal. it is probably a viral tumor called papilloma, it is not considered to be life threatening and it usually takes several months to a year to resolve without treatment, a treatment with a special antibiotic called Zhitromax helps in some cases. i would recommend taking Langley to the vet ASAP in order to get it checked.

This is quite a strange looking growth. I feel it is likely a papilloma which has become devitilised and died off hence the pale colour. However it is impossible to know the origin of a mass just by visual inspection alone. To be safe I would have this lump removed and submitted for testing at the lab to know exactly what it is.

Unfortunately this picture is just too blurry to speculate on what this is. However it is in the general vicinity of where the dogs anatomical incisive papilla is located. The incisive papilla is abnormal anatomical finding that is sort of bumpy (not ulcerated as you described) and aids the dog in smell. Here is a link to one in another dog http://www.dailydogdiscoveries.com/mysterious-bump-in-the-dogs-mouth/ If this is not similar to what you are seeing then it's best to get a second opinion from another vet who can look at this area in person. Best wishes.
