LMAO!!! That was just too funny.... God luck....LOL! :-)
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.
God luck!
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.
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
