My dog has hairless, draining lumps on leg and chest. What are they?

Question

My five year old pit mix has a large hairless growth on her leg. It doesn't seem to trouble her. It's completely solid it's about an inch raised off her leg. Sometimes, it looks like it's draining, but nothing really comes out. Now she has one on her chest that's starting to lose hair around it. She runs, plays, eats and drinks like nothing is bothering her. What could these be? Pet's info: Dog | Mixed Breed Large (61lb +) | Female | spayed

Anytime a new mass is noticed, I always recommend having it evaluated to see what it is and if anything needs to be done about it. Unfortunately, we can't tell anything about a mass by just looking at it. Your vet can perform a simple test called a fine needle aspirate where they use a small needle to collect some cells from the mass, then look at them under the microscope. They may even need to send the cells to the lab for a pathologist to examine them, so we know what the mass is. If it is benign, you might not need to do anything about the mass at all, but if they see cells that worry them, they might recommend removing the mass. So, I would recommend having your veterinarian evaluating the masses you have found on Sadie just to be safe and give you peace of mind to know that they are benign. Good luck! I hope that was helpful. Thanks for using Petco Pet Education Center, formerly Petcoach.
