Tapeworms commonly infect dogs who hunt and eat rodents, or clean up rodent kills provided by an accommodating cat. The other source of infection is ingestion of infected fleas. This most often occurs when the dog travels out of Central Oregon to an area that supports a more robust flea population or a dog visiting from one of these areas provides an infestation.
Venomous rattlesnakes are present in certain areas of Central Oregon, particularly along streams and rivers. They tend to be timid snakes but do pose a threat to inquisitive or aggressive dogs. Most strikes from the common Pacific Rattlesnake are dry, that is without venom injection. Venom, even in small quantities, can potentially cause acute allergic reactions, tissue damage, or infections. Rattlesnake vaccines are available but are of questionable advisability.
Both does and bucks will aggressively attack dogs, particularly when fawns are present and during the rut (Fall breeding season). These attacks can result in fractures, internal injuries and death.
