Alright, so I've had my dog for what seems like forever (10 years), and I cannot even remember a time without her. Well, lately things have gotten a little scary. I have discovered a well-sized oddly shaped bump on her stomach by one of her nipples. As normal, I am worried. Could it be cancer? She has gashed this n****e open in the past, so could it be an infection? I will be taking her to the vet soon, but I just wanted to know what you guys think. Thank you for any responses.
UPDATE: She is a miniature toy poodle. Reason why I am stating this is because the poodle breed has been found to have an increase in the likeliness of cancer. She has never been spayed. She has never had a surgery before, and no complications until now. She shows no signs of discomfort, although I am still worried for her well-being.
