Seriously Carlos can’t tell the difference it’s easy to know canines and humans have different set of teeth just look for the indentations and he’s a doctor!
I guess he just doesn't want more kids in the group to potentially distract Sarah and decided to kill Clem without the whole group freaking out by making up that condition to wait until the morning. If you got bitten like that by a dog and didn't get a proper cleaning, you will be infected and has a high fever in the morning regardless.
I'm gonna be honest, cant blame them, they went thru something similiar arleady and its been some time into the apocalypse. Plus like everyone else said, they haven't seen a dog in a long fucking time, most of animals are either eaten by walkers or stay the fuck away from humans no matter what
The dog bit her several times in the same area. That wound is all kinds of messed up, it would make sense he couldnt say for sure since walkers do the exact same thing.
