What is this lump on my senior dog's leg? Should I stop walking her?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed | Female | spayed | 70 lbs

Hi I have a 13 year old dog which I rescued a few months ago and was told she was a cross between a collie and a Labrador. I have spotted a large lump on the side of her leg and was wondering if you would have any idea what it is? I have been walking her but don’t know if I should stop. Thanks in advance.

As long as she isn't lame or sensitive, you can continue to walk her. Without a physical exam or diagnostics, it is difficult to determine if the lump is a benign or malignant mass, infection or injury. Your veterinarian can perform a fine needle aspirate in the clinic to collect samples for pathology. X-rays may also be indicated to rule out bony involvement.
