Hello & welcome, I am Dr. B, a licensed veterinarian and I would like to help you today.

How long has this been present?

Is it firm, soft, fluidy, or sore to the touch?

Has she had any injections in this site recently?

Any rough housing with other dogs or injury at this site?

Can you take a photo of this to let me see what you are seeing? To post a photo, you can use the paper clip button on the tool bar above the text box. Or if you cannot see that on your phone/computer, then you can post them on any site (ie Flickr, Photobucket, Imgr etc) and paste the web link here for me to have a peek

It has only just come, yes she has had injections in this site recently, and it is soft and fluidy, it does not appear to hurt her at all

Thank you,

Now as I am sure you can appreciate when we see any lump on our pups, we do have to consider a range of issues. If she had an injection recently, we could have a mild allergic reaction, hematoma, or infection (abscess). Of course,we can also see this with non-related trauma induced hematomas, soft tissue swelling, abscesses, and insect sting induced allergic reactions.

Now with these in mind, we can start some supportive care to try and rule out some of these. To start, since we may have an allergic reaction here with Tyler, we can try to counter that with an antihistamines. Commonly we will use Benadryl (Diphenhydramine). A low dose (ie. 0.5mg per pound of body weight twice daily) is often enough to reduce these signs over a few days. We do usually like to keep the dose low, as they can have drowsiness with this medication (just like people). As well, of course, this medication shouldn't be used if your wee one has any pre-existing conditions or is on any other medication without speaking to your vet first.

Furthermore, to reduce swelling with any of these sudden appearing concerns, you can also start warm compressing this lump. This can reduce inflammation as well as encourage hematomas and allergic reactions to settle. Just to note, you can make a safe warmer for use as a warm compress by filling a clean sock 2/3rds full with uncooked white rice. Tie it closed and microwave (approx 1-1.5 min). Before use, do make sure to shake to allow the heat to distribute before using as a compress. (If it cools, you can re-warm as required).

Now if you use the above, but the lump doesn't settle within 24 hours, then it does mean that we need to consider those other issues. In that case, we'd want Tyler's vet to evaluate the lump via fine needle aspiration (FNA). This is where the vet uses a needle to harvest cells from the lump. If the remove pus, then this tells us that there is infection present and antibiotics can be dispensed. If blood or blood stained fluid is removed, then trauma was most likely and pain relief/pet-safe anti-inflammatories can be used to settle the swelling.

Overall, if this lump is sudden in appearance, we would consider those initial sudden onset concerns for Tyler. Therefore, as long as it’s not painful or obviously draining pus, then you can try the above to rule out those aforementioned concerns. Otherwise, if this doesn’t settle over the weekend; then we’d want to have your vet sample this lump to identify its cause so that appropriate treatment can be initiated to address it for her.

All the best,

Dr. B.
