This is definitely for the vet. Your dog may have been bitten by some wild critter like a snake. If you see ANY abnormal behaviors before Thursday, go to the vet right away. - Blu
She's acting normal. The only time she acts like its bothering her is when I touch it and she just pulls her face away. Theres no snakes around these parts either.
One of my dogs had something similar come up on his flank. It was a little larger than a nickel. The vet aspirated it to make sure it wasn't cancerous and prescribed a combo of oral and topical antibiotics to clear it up. It's been well over a year and no recurrence.
I agree with Blu. Keep a close watch and if anything changes, go.
LMAO!!! That was just too funny.... God luck....LOL! :-)
