Lump & diarrhea after dog's vaccines. Should I see a vet before boarding?

Hi there! I'm sorry to hear about Bruce's lump. Vaccinations can definitely leave behind a small bump at times. If this happens after I vaccinate a dog, I will have the client bring their pet in so I can examine the spot, make sure that it coincides with where I gave the vaccine for sure. If it is something new rather than a lump from the vaccine, it can be addressed accordingly. As long as it is just from the vaccine, then we monitor the spot over the course of a few weeks. If it is a localized inflammatory response to the vaccine, it usually will go away over time. If it persists, some clients will opt to have me remove the tiny lump and test it to make sure it just comes back as an inflammatory response and not something serious. I would definitely call your veterinarian and have Bruce get a quick examination to make sure all is well, and you will likely just monitor the lump going forward. I hope you find this answer helpful. Best of luck!

I wouldn't worry about the lump just yet, but I would have it checked out by the vet on Monday. This lump could be a cyst, an abscess, a lipoma, or a benign tumor. Any suspicious lumps should be examined by the vet. 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. Once the vet diagnoses the cause of the lump, they can discuss treatment with you.

It would be hard to say if the vaccine is related without knowing what vaccine was given and how Leo has reacted in the past. Sudden behavioral or health changes are always concerning, so I would definitely bring it up with your vet and have Leo come in for an exam. Accidents can sometimes indicate underlying pain or illness, so ruling out more serious issues is best. I would also let your vet know about the lump that developed so they can monitor it or change how any future vaccine are given to Leo to help minimize reactions.

I suspect that the lump may be where injections were given, but it would be best to ask your veterinarian about this when they are available Depending on how long ago the injections were given, it may indicate any infection. If the injections were given recently (within the last 1-3 days), then I would not worry too much about it and just monitor it for now. If the lump is still there two weeks after the injections were given, or continues to grow, then I would recommend having your vet evaluate it sometime soon. I hope that helps and all is well with Daisy.

Hello, thank you for using Petco Pet Education Center, formerly Petcoach! It could be any of those things: a localized vaccine reaction, a reaction to her microchip (if she has one), an insect sting.... no way for me to tell you which. Just call your vet to discuss when you can. Take some photos of the lump so that you can maybe send to them so they can decide if you need to bring her in or try some home treatment first.

Thanks for using Petco Pet Education Center, formerly Petcoach! Possible side effects after vaccines include pain at the injection site, diarrhea, lethargy, inappetence and general discomfort. This should subside within 1-2 days. If it does not improve or it worsens, have Jenny evaluated by a veterinarian for further assessment and treatment. Otherwise, Jenny will likely start feeling better shortly. Good luck and best wishes!

Hi and thanks for using Petco Pet Education Center, formerly Petcoach! Sorry to hear about Sadie. Lumps are always troubling unless they resolve over days to a few weeks. Possible causes for lumps include recent vaccinations, seroma (fluid filled space), hematoma (blood filled space), granuloma (growth consisting of inflammatory cells), cyst (fluid/sebaceous material filled sac), or a tumor which could either be benign or cancer. I would monitor the lump for signs of resolution as noted above. If the lump increases in size or the characteristics change, then I would advise that your vet see Sadie. They can perform a physical exam and then possibly a fine needle aspirate or biopsy of the lump if indicated. Hopefully this will resolve. I wish you and Sadie much luck.
