Problem: Will an opossum attack my pets? Solution: In general, opossums are docile, non-aggressive animals and will not attack your pets. They prefer to avoid confrontations. If escape is not possible then the threatened opossum may “play 'possum”, show its teeth, or bite in self-defense, as any animal would.
What happens if a possum bites my dog?
The real threat your dog faces from an opossum bite wound is the chance of infection. An uncleaned, untreated bite wound can contain plenty of dirt and bacteria. Without treatment, the bite wound may become infected and cause complications including fever, vomiting and diarrhea.
What do you do if your dog comes in contact with a possum?
Do not attempt to engage with the possum or scare it away. Just focus on getting you and your dog away from it. Then check your dog for injuries, and call the vet. It is very rare that a possum will carry rabies, but not impossible.
