Final answer:
Limping is not typically associated with canine distemper; the common symptoms are coughing, seizures, and behavioral changes. Distemper is a viral disease and should not be confused with conditions like German measles, which is caused by a different virus.
Step-by-step explanation:
The clinical sign that is not associated with canine distemper is limping. Canine distemper is a serious viral illness that primarily affects dogs, but can also occur in other animals like ferrets and raccoons. The signs of distemper include coughing, seizures, and behavioral changes, among other symptoms. Limping is not a typical sign of distemper; instead, it could be indicative of an injury or another condition like arthritis. However, it's important to note that while limping is not a primary symptom of distemper, the virus can lead to neurological issues that might indirectly cause a dog to limp due to weakness or paralysis.
To provide insight into other issues, the diseases not associated with coronavirus infections include German measles. Coronavirus infections are linked to respiratory illnesses, including the common cold, severe acute respiratory syndrome (SARS), and Middle East respiratory syndrome (MERS). Contrastingly, German measles, also known as rubella, is caused by the rubella virus, not coronavirus.
