Thanks for the well wishes everyone! Niņo seems like he now feels close to 100%. We decided not to take him to the vet because He'd most likley just say to wash it and put antibiotic cream on it. I think I'll be giving Niņo his very first ever haircut today so that I can see and clean all the little marks too. I don't think I'm going to hold the owner responsible, I don't even know where about they live.
