Poor Hooch! I understand your concerns. Her tumor is quite pronounced and is suspicious for a mammary gland tumor given the location. Fortunately for dogs, 50% of these tumors are benign. However, it is concerning that it has gotten this large over a few months. Hooch should go to the vet sooner rather than later and will likely need to have this mass surgically removed and biopsied to determine if it is benign or malignant. Your vet will also discuss if chest x-rays are indicated to determine if cancer has spread to the lungs (if this mass is malignant). I hope that all goes well!
