Need help, his tail is up and his neck is swollen

[Noegal]

I have two male (the breeder said male anyway) and they're still young enough and his tail started to stay upright and the overnight his throat started to be all puffed out and it looked like when he ate he had small black dots or lumps inside his mouth and I truly have no idea what to do

It could be fluid retention which is normaly caused by infection or failure of kidney or liver. You should take your axie to the vet as soon as possible. Do you think you could post some pictures? It would help a lot
