  • The first and most important thing you should do when your dog kills a possum is to take your dog away from the possum to avoid further attacks and ingesting the dead animal. 
  • Then, examine your dog thoroughly to find any scratches, wounds, or bleeding. Possums attack vital places like the stomach, genitals, eyes, neck, and chest.
  • Wash the dog with warm water and hydrogen peroxide or unscented soap. Use an antibiotic ointment for minor scratches, and if there are deep wounds and cuts, take your dog to the veterinarian immediately. 
  • Ensure you wash the dog well, even if there are no wounds and scratches, as the dog’s coat might contain parasites, saliva, and urine from the possum that transmit various diseases. 
  • You must also deal with the dead possum if your dog killed a possum. Make sure to remove the carcass by wrapping it using a plastic bag and place it in an outdoor trash can. Or else, you can contact the local animal control to take care of the body. 
  • Confirm whether the possum is dead, as they play dead sometimes. If you are not sure, contact local animal control. Make sure you keep an eye on the possum in case it escapes. Besides, try to trap it without touching it until the animal control arrives.
  • Consequently, monitor your dog well because the dog is likely to contract a bacterial infection. 

How Do Possums Respond to Threats or Perceived Danger? 

Possums are usually docile animals and non-aggressive.

They try to avoid confrontations, but if cornered or feel threatened, they hiss and use their sharp teeth and claws when under a dog attack.

Unlike a baby possum, most adult possums can survive a dog attack.

The most interesting fact about possums is they have a defense mechanism called ‘playing possum,’ as in, they play dead when there is a danger.

They can carry on this act for up to four hours until the dog loses interest in attacking them.

How Does a Possum Bite Look on a Dog’s Body?

Possums have six incisor teeth: two on the lower jaw and four on the upper jaw. If your dog attacked a possum, a noticeable bite mark can be visible, as possums have sharp teeth that are 4.5-7mm wide. Yet, finding bite marks on the canines with thick coats is impossible. This is why meeting your vet is crucial. 

Symptoms of a Severe Possum Attack on Dogs

Do Dogs Get Rabies From Possums?

The main concern of a dog owner when a dog kills a possum is rabies!

The chance of a dog contracting rabies is more or less slight. Most of the time, possums do not carry rabies.

The reason is possums have a very low body temperature of 94 to 97 degrees, unlike other mammals.

Hence, the rabies virus cannot survive and thrive in such a low body temperature.

If you suspect your dog killed a possum with rabies, take a trip to the vet immediately. Also, examine closely for rabies symptoms like changes in average body temperature, drooling, aggression, and abnormal behavior.

At the same time, if your dog has had the rabies vaccine, there is a very slight possibility for it to contract rabies. So make sure your dogs get the rabies booster shots on time. 

How to Ensure the Safety of a Pet Owner? 

The safety of pet owners is crucial when a dog kills a possum. Possums are wild animals that carry parasites and diseases. Make sure you wear gloves when you check your pooch. Contact Wild Animal Control if you are unsure whether the possum is dead or playing possum. 

Wear Gloves and a face mask when you dispose of the body, and clean possum poop to avoid contacting your skin.
