first of all i thank you for your advice and concerns. so to clarify this, i was to a regular vet who told me to use this anbitiocits that in my country is called fortum . in my country i dont have vets with reptile experience(so i dont know if i should trust them or not since they cant treat properly a dog,,,anyway). he told me to do the shots , so i came here to be sure i was doing the right thing.
i dont have any medical experience with reptiles . and ofc i made the right dosage. dont judge so harsh people who want help . i just want to help my snake and find out how he got sick. and yes i dont know english at high level but i dont think that i write so poorly. this been said i will do my best to treat him and again i apreciate your concerns and help . i hope he will be ok soon. i will come with updates.
