My dog has a lump under skin. Is waiting for removal too long?

Updated on September 23rd, 2025

Pet's info: Dog | Mixed Breed

My Goldendoodle had a lump and I took her to the vet for an aspirate. When she looked at it she said it looked angry and had some red and white blood cells. She said she wanted to remove it and send for pathology. Appears like a lump under the skin. She said it isn't anything now, but she believes that it could turn in to something. (1) We can't get an appt. to have it removed until the 18th. Is that too long to wait? (2) What type of abnormality do you think she is leaning towards? Thanks.

Hi and thank you for using Petco Pet Education Center, formerly Petcoach. If the lum has not gotten bigger and remains stable in size and character, I think it is safe to wait until the 18th for removal. Your veterinarian is likely concerned the mass is cancerous. Therefore she is likely recommending removal for a better diagnosis. It really could be anything, from an infected cancerous mass or an infected benign mass. Removal of the mass and sending it for histopathology would be the gold standard for diagnosis and prognosis.
