Here's why:
* Different species: Dogs and possums are different species with different immune systems and blood compositions. This makes it very difficult for diseases to transfer between them.
* Transmission methods: Most diseases are transmitted through bites, scratches, or contact with bodily fluids. While possums can carry diseases, the risk of transmission to dogs is relatively low unless there is direct contact, like a bite.
* Parasites: Some parasites can be transmitted through contact with possum feces, but these are not blood diseases. For example, roundworms are a common parasite that can be transmitted from possums to dogs, but they don't affect the blood directly.
However, it's important to note that:
* Possums can carry diseases that can affect dogs: Although there are no blood diseases, possums can carry other diseases like ringworm, salmonella, and leptospirosis, which can be transmitted to dogs through contact with their feces or urine.
* Preventative measures: It's always best to keep dogs away from possums and to avoid letting them eat possum carcasses. If your dog does come into contact with a possum, it's important to wash your dog thoroughly and consult a veterinarian if you notice any signs of illness.
If you have concerns about your dog's health, it's always best to consult your veterinarian for advice and diagnosis.
