My dog has a lump near her nipple. Should I see a vet before our trip?

Poor Daisy! A lump in the breast can be a cancerous tumor, a benign tumor or can be an infection. I recommend to have Daisy examined by her veterinarian today if possible. Best of luck and please feel free to post any additional questions.

Thanks for using Petco Pet Education Center, formerly Petcoach! I think it would be worthwhile having her evaluated to make sure that it does indeed look like a nipple and to ensure it is not something else like a mass or nodule. Based on an examination, your veterinarian would be able to tell you if this should be biopsied or not. Good luck!

You can apply a warm compress to it to help with pain and swelling. She will need to go to a vet to have it checked as it may be an infection or a growth. If she is nervous or anxious then i would call and see what arrangements can be made to minimize her stress. Such as medication for anxiety prior to travel or not waiting in the lobby with other dogs and people but maybe and exam room or the car until they are ready for you.

I do not see anything immediately concerning on the pictures but it is recommended to get all lumps checked by your vet to rule out sinister causes, especially if there is any change in size, colour or texture. Some changes will occur with puberty and this may be what you can feel

As long as she is otherwise acting ok, it is not growing rapidly, and/or has a discharge then you could wait and take her this weekend. Your vet can do a needle aspirate to help determine the cause and determine if the lump needs to be removed or treated.

It seems a little far off to the side be associated with her mammary gland. Since it just came up, you can monitor it for any changes m. It is gets larger than have her checked. If it does not change it maybe a cyst or fatty deposit and not an emergency problem.

I see that Jessabell isn't spayed. Unfortunately in unspayed females, mammary tumors are common and that is what could be causing her nipple to look weird. Mammary tumors in dogs have a 50% chance of being malignant, so I would recommend having her seen by a vet for it. The vet can perform a test called a fine needle aspirate on it. To do this, the vet sticks a small needle into the lump to get a sample of it's cells, and examines the cells on a slide under a microscope. It's usually painless to the animal, and relatively quick to perform. Should she have a mammary tumor and it's malignant, it will need to be removed surgically and local lymph nodes should be checked to see if it has been spread. I would have Jessabell seen by a vet tomorrow to have her nipple looked at so it can be treated as needed.
