Dog parks all around the state are warning of a highly infectious and deadly strain of dog flu. The Indiana State Department of Health says there have been at least a dozen cases reported in northwest Indiana in the past week. This illness is spreading from state-to-state. There are multiple dog parks in the Indianapolis metro area, also known as “Bark Parks,” ranging from Eagle Creek on the west side to Broad Ripple on the northeast side. As this dog flu is spreading, veterinarians say to look for symptoms in your pooch like a runny nose where the discharge progresses from clear to thick yellow-green mucus, trouble breathing, sneezing, coughing, fever, loss of appetite, and sluggishness. Know that this canine flu is contagious and can be passed from pet to pet and from humans to pets.
