What is a common parasitic condition found in dogs?

Lyme disease is a common parasitic condition found in dogs, primarily caused by the bacterium Borrelia burgdorferi, which is transmitted through ticks. Ticks are external parasites that can attach themselves to various animals, including dogs, and can lead to various health issues after prolonged exposure. Lyme disease is noteworthy due to its potential severity, impacting a dog's joints, kidneys, and overall health.

In contrast, the other options listed are viral diseases: Parvovirus is a highly contagious viral infection that primarily affects puppies and can cause severe gastrointestinal disease. Rabies is a viral disease that affects the central nervous system and is typically transmitted through bites from infected animals. Canine distemper is another viral illness that can affect multiple body systems, including respiratory and neurological. These options do not fall under parasitic conditions, highlighting why Lyme disease stands out in this context as being a relevant example of a parasitic condition in dogs.
