Hi my dog is a chihuahua and she's had these bumps on her stomach for a long time now, it doesn't seem to grow nor bother her when we rub her stomach but I still want to look into it. Should I be worried? Do you have an idea of what it could be?

Thanks for using Petco Pet Education Center, formerly Petcoach! This looks like a mammary tumor. This could be a benign or malignant growth. This is often differentiated by a test called a fine needle aspirate (FNA) which is a pain free, inexpensive and easy procedure which in most cases will help reach a diagnosis. Sometimes a biopsy is needed for a definitive diagnosis. I recommend that you have her evaluated by your veterinarian for further assessment and treatment. I am really hoping for something benign. Good luck and have a good day!
