It's actually quite shallow, but I am keeping a close eye on it.
Yeah, it stings, but other than that, it's minor.
As soon as I got home I gave it a good wash with soap and water and applied antibacterial ointment.
Not one of the neighbour's dog, but a dog on my route today. It was my first stop. They guy was out playing fetch with his dog, I delivered the package, took my picture and was leaving when the dog barreled up to me and nipped me.
People, if you're expecting a package, lock. your. dogs. up. They can be the friendliest beasts on the planet, but if a stranger comes up to your porch, they may bite.
