stray pup outside 7-11

Found a little stray pup sitting outside the 7-11 by my soi last night. Maybe 3 months old, very skinny, ticks all over his ear. I could not just leave him there so I put a towel on the car seat and he slept the whole way home. Tuna went crazy barking when I came in, he did not like the new smell at first lol. Next morning I took him to the vet near Rama 9 road. They gave him deworming and flea stuff and said to watch his appetite. He eats well now. Still not sure if we will keep him or find a family. The owner might have put up posters, I am going to check the lamp posts this weekend.
