Guinea pigs have a lot of bacteria in their mouths and the risk for infection with a bite wound is high. If the wound is small and shallow, you can use antibiotic ointment (like Neosporin) to keep infection away. If you do use antibiotic ointment, use as small an amount as possible. If the guinea pig licks and eats it while cleaning itself, it can hurt their digestion and cause diarrhea.
If the wound is too large then you may need a veterinarian to prescribe antibiotics for it to fully heal. If a deep wound gets infected and then closes up on top of the infection, an abscess will grow which will require surgery plus antibiotics to fix. It is much easier and less expensive to take the guinea pig to a veterinarian for antibiotics now than to wait and have to see the veterinarian for antibiotics plus surgery later.
How do you get them to stop biting? I have had no problems with guinea pigs biting before. I really don't think she like us (mostly me) she's better to my mom but chomped on her good today. I know when it happens, sometimes it has to do with food, but last weekend all I did was reposition her a tiny, tiny bit on my lap and she whipped around like a cat and bit me so hard. I started crying, and I'm 26 haha. But I'm getting frustrated with her doing this.
