Lump after vaccines.

Species: Dog
Breed: Chihuahua
Age: 6-12 months
...Hello! My name is Jessie and I have a Teacup Chihuhua named Zeep. He is about 10 months old and his next shots after baby shots last week. They gave him five shots. He had one of them in his scruff area and just a couples ago I noticed a small lump in the scruff area while I was petting him. I do remember that during his shots he didn't express much discomfort until the scruff shot- and he was really in pain it seemed. There was definitely not a knot there before the shots. I also noticed some skin discoloration where his fur meets the skin on his belly. He has been acting normal and peppy as usual but I am still worried. I love my pup very much and I would like some advice please. Thanks.

Dr. Marie replied:

This certainly can be something called a vaccine granuloma. A vaccine granuloma is a lump that appears after a vaccination.

In most cases they are nothing to worry about and go away in a few weeks. But, it is still a good idea to have your vet take a look just to be sure.
