I've put neosporin on Miya before, it was fine. I think in large amounts in can cause diarrhea if they lick it, but Chloe is so small I wouldn't worry about that. Have you thought about a mesh harness. You use park ave don't you?? I was kinda worried about using anything besides microfiber or mesh for that reason. I hope her sore heals soon
Meanwhile, I have to run because Miya is pulling out EVERY SINGLE one of her dang toys..sheesh.
