The phrase "infected dogs" refers to canines that have been affected by a disease or illness caused by pathogens such as viruses, bacteria, parasites, or fungi. These animals may show symptoms like lethargy, loss of appetite, fever, coughing, sneezing, vomiting, diarrhea, skin irritation, or other signs of illness depending on the specific pathogen involved. Infected dogs can spread their disease to other animals and humans through direct contact, respiratory droplets, saliva, feces, or contaminated surfaces. Proper veterinary care is necessary to treat infected dogs and prevent the spread of infection to others.
