Please have her checked by your vet as soon as possible. This is not normal and although any lumps are concerning, any that are painful or rapidly growing are very suspicious for underlying issues such as cancer. Early diagnosis and treatment is vital to improve outcomes and reduce undue pain and discomfort.

    Poor sadie, these signs are very concerning and indicate severe illness. Diabetes, kidney disease and cancer would all be possibilities, please arrange an urgent veterinary assessment for her immediately
