Thanks for your query.
In case of dog bites the general recommendation is to get a tetanus
shot, if ten years have elapsed from your previous shot. Thus visit your physician so that he can assess your immunity levels for tetanus.
Next thing to evaluate is if the wound is showing some kind of infection. For this examination of the wound by a physician is required.
Also nerve damage
needs to be evaluated in your case. Minor nerve damages are left to heal by themselves. In case of major nerve damage, some surgery may be required.
Lastly, you also need to observe the dog for ten days for symptoms of rabies
. Since the dog is a pet, I will not be so concerned about it.
Try to look for doctors in your area that provide services in low cash.
I hope I addressed your concerns
