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

Hi there! A small lump at the area of a vaccine is fairly common. It may take a couple weeks to go away and is usually nothing to worry about. Do keep an eye on it for any redness, heat, soreness, or discharge - these are reasons to re-visit the vet. The diarrhea is probably unrelated to the vaccine, and can be caused by dietary indiscretions (e.g. too many new treats). If he is acting normal and not experiencing any vomiting, you could try giving his stomach a rest for 6-8 hours by not feeding him, then reintroducing small meals of boiled chicken and rice. If the diarrhea continues after this or any other symptoms develop, it's time to see the vet. I do worry about dehydration in young dogs that have severe diarrhea, so please bring him in if he starts acting lethargic. Good luck, and I hope Jack gets well soon! :)

Sometimes after vaccinations dogs can be sore from them. They can also get a localized reaction which can feel like a lump where the vaccination was given. I would call your veterinarian and explain your concern. They can prescribe an anti-inflammatory for him and can evaluate the lump to see if it is a localized reaction. This is not an emergency unless he is in a severe amount of pain so you can wait until your regular veterinarian opens tomorrow. Thank you for using Boop by Petco.

Hello and welcome to Boop by Petco. Lumps and bumps can be many different things, including inflammation (reaction to vaccine is possible), infections (this could be a small pocket of pus), tumors that are both cancerous and not-cancerous, foreign objects stuck inside the body causing inflammation/infection, etc. I recommend you have your boy back to your vet where you had the vaccine and have them check to make sure it's nothing serious. They will likely put a needle in the mass and see what type of material is present inside, and this will lead their treatment plan. This doesn't present like a bee sting. Best of luck with your boy!

Hi, thanks for using Boop by Petco! Yes, Luna should be fine. It isn't uncommon for a pyogranulomatous reaction to occur at the site of vaccination. This forms a painless lump in the subcutaneous tissue. It should resolve on it's own in a few months. I most commonly see if with the Rabies vaccine. Have a great day!

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.

Hi, thanks for using Boop by Petco! Yes! Injection site granulomas can be seen at the site of vaccination. They are non-painful, moveable but firm and are about the size of a marble at the location of the vaccine. To confirm call your Vet and tell them where it is and ask if a vaccine was given in that location. I have ti most commonly happen with the Rabies vaccine. They do go away on their own with time. Have a great day!

Hello and thank you for reaching out to Boop by Petco. I'm sorry to hear that Apollo had some diarrhea after receiving his vaccines. It is not unusual for puppies to experience mild vaccine reactions, which can manifest as a small amount of vomiting and/or diarrhea. Apollo may be more lethargic/sleepy after his vaccines too. As long as he is otherwise acting normally and is not vomiting repeatedly or experiencing any other abnormal clinical signs (itchy skin, redness, etc) he will likely be OK. If you are ever concerned that he is not acting right or seems very dumpy, he should be seen by a veterinarian right away. I recommend still letting your veterinarian know that Apollo had this reaction so they are aware of it for next time. I hope this is helpful!

Hello, sorry to hear about your pup. Yes indeed, vaccines can cause local reactions and lead to lump formations that can be painful to non-painful, firm to soft, and of varying sizes. Most of the time, the masses are self limiting and will resolve. Occasionally, the masses will remain and need to be removed, in even more rare instances vaccines can lead to tumors. I would recommend contacting your veterinarian to inform them of this bump and have them evaluated to ensure it is not getting worse. Hope this helps and best of luck.

A lump may develop at the site of injection. It typically resolves on its own. See your veterinarian if the lump grows, becomes painful or if the pup develops a fever, becomes lethargic, begins vomiting or has diarrhea or loss of appetite.
