Maddie had a reaction to her shots this year. She didn't have a reaction the year before.
This year she got her round of shots. A couple of days later she had this golf ball size lump between her shoulder blades. I asssume the worse - she has a tumor or something and she's going to die. I called the vet in a panic and they said some dogs have reactions and it will go away in a few days and next year we will have to do something different.
So, I know how you feel. They are tender for a few day. Imagine if you got that many shots all at once. You'd be tender too! Just pamper your baby - they will feel better soon.
