Our Copper dog is not doing great. I am not sure if he has sat down once today and was coughing something fierce this morning although nothing came up. Concerning is that was the beginning of the end for both of my previous 2 coonhounds with their barrell-chests. Am furious with our vet right now though. Been a great customer for 8 years with 2 dogs the entire time and they told me they are too busy to see him, go to the ER vet….
