Is OTHER wrong in the post ? POST : My friends got a puppy. She was infested with fleas from day 1. I don't want fleas in my home or my pets to be infected with something,  so I said 'can you wait until the all clear from the vet'? No problem. They got the all clear and started leaving the puppy with me to babysit or to hang out.

I start to notice that sometimes my animals are showing signs of bugs, even though they're treated. I am also covered in bites. The itching happens only after the puppy is over and lasts a few days.  I check the dog, and she's covered in bugs. I ended up finding out that she's never been tested or treated for any parasites! I've now said the dog is no longer allowed over at all. They think i'm over reacting and have stopped coming over.  A neighbor sided with them saying "if your pets are medicated and vaccinated, what's the problem?" Am I being an asshole about this?
