What is that?

Daddy found a spot on my body and off I went to see Dr Kenneth... he said it was nothing serious... so gave me some cream... and daddy requested for heartworm protection just in case... so I got 2 jabs.... ouch ouch.... but I was brave.... just whine on the first jab that was on my front leg.. that hurt more though it was a tiny needle.... anyway... I am ok... the rash is better and I hope no more bites....
