He was never vaccinated since in my country (Georgia, East Europe) even vets think guinea pigs are not supposed to be vaccinated or even taken to the vets, usually none of them specializes in rodents or exotic vets and people do not take good care of them. However I take a good care of him, he always has clean food, hay and wood shavings of a brand (not like I bring them from nature like some owners prefer). Also, I do not let him on the floor (because we walk on them with shoes so I have been considering hygienic reasons always).
These are photos of my bite. I am very allergic so if I decide to get a shot, I have to be first tested on that and take a consult from my allergy doctor, etc. It will be exhausting and I am just recovering from some serious flu with bronchitis. I would really not like to have any shots right now if it is not actually necessary.
Please advise should I get vaccinated and which one rabies, tetanus, anything else? I will be very grateful for every comment
If your guinea pig has been out in the wild and could have come into contact with a rabid animal, then you should go to a doctor and inquire about shots. But if your guinea pig has been kept indoors and you've had him for longer than a week or so, then I don't think you need to worry about it. You should, however, wash the wound and bandage it as per what others have said, because it can get infected.
The only one that you might be at risk for specifically from a bite is Pasturella, which is still very rare in guinea pigs. It causes painful wound infections that are serious and fast-progressing, but if you don't see symptoms yet you probably won't. Other than that, there shouldn't be any diseases a bit would put you at increased risk of (at least, no common ones) so just treat it like you would any other wound - bandage, antibiotic ointment, etc.
