Dog bites can range from mild to severe, but the initial injury may not always indicate where in the range your injury will fall. One of the biggest risks with any bite from an animal that breaks the skin is infection.
According to Forbes, there are some dangerous infections that can result from a dog bite even if that bite does not initially seem serious.
This infection is usually worse with deeper bites. It can be fatal if you do not get treatment quickly. The most common treatment is antibiotics, but you must ensure the doctor uses the right antibiotics because there are some that will not affect it. Penicillin is the most common treatment.
This infection is usually not too bad for most people, but if you have a weakened immune system, then you are most at risk for complications. There is a 30% chance of death from this type of infection, which is rather high. One issue is that it is a rapidly progressing infection. Treatment is typically antibiotics.
This infection will cause diarrhea, which can be severe and require hospitalization. If you can avoid complications associated with the diarrhea, then recovery is good. The biggest issue is that, again, doctors typically treat this with antibiotics, but it is quite resistant to most options.
The best-known infection is rabies, but this is actually the least likely. Most dogs will have gotten rabies vaccinations, so you will not risk exposure. However, in unknown dogs, there can be a risk. You will require a quick diagnosis and treatment to avoid complications if the dog was positive.
