Pet's info: Dog | Dachshund | Male | neutered | 6 years and 9 months old | 16 lbs
Hello,my dog has had a lump on his chest for about a year now. I took him to the vet to get it checked out and she said it is a benign cyst. I just describe the to her and she didn't feel over or anything. It's soft and not a perfect shaped bump,its not growing you can pick it up and move it around. I was concerned beacuse she didn't really look at it. It has not changed in shape or color. Do you think she was right? I was wondering if you knew what it could be. I wanted advise from another vet.

Hello and thank you for reaching out to Petco Pet Education Center, formerly Petcoach. Typically, if a mass is not changing in size, and is soft and freely movable, most of these masses are benign and nothing to worry about. The only way to know for sure is for your veterinarian to sample some cells from the mass, either via a fine-needle aspirate, or with a larger biopsy and evaluate the cells under a microscope. Since it is small, soft, freely movable, and unchanged over the course of a year, your vet likely believes this mass is benign and feels comfortable having you monitor it at home. I hope this is helpful - best of luck with Oscar!
