Pet's info: Dog | Beagle | Female | spayed | 7 years and 3 months old | 48 lbs

Good day. My pet has a formed a red bump it doesn’t seem to pain her when I press it. It irritates her every so often I will see her licking it or nibbling at it. It does not move. It is extremely Red, it looks like it has a entrance spot on it. It is hard, and bloody looking. I tried to shave the hair for a better picture. What can this be? Is it cancerous?

Unfortunately, growths like this can't be determined if they're cancerous or not without an actual biopsy or sample of the spot to check what cells it is made of. That said, many other things can cause growths like this, such as cysts, blisters, infections of the skin, benign tumors, etc. I would have it checked out by your vet in person so they can take a sample if needed, and can also help clean or remove the spot if needed. If the spot is bothersome, an Elizabethan (cone) collar can be used to keep Princess from licking and chewing at it, as letting her lick at it can lead to irritation and secondary infection taking hold (which can make it even redder and more irritated). Keeping the area clean and dry and monitoring it for any changes in size, shape, color, or discharge can also be useful in helping your vet determine what is going on.
