Anyone dealt with it before? I think my older dog has it I have no idea how she got it though! Unless our neighbor's dogs have it (lots of dogs in a small trailer). She started a few days hacking up mucous, I thought she had something caught in her throat (which is actually how it's described), but it's not getting any better. The couple vet videos I watched recommended letting it run it's course... but at what point do I need to take her in? We have a second dog as well. The one that has it is a medium size (48 lb) 10 year old dog, the other dog is a smaller (21 lb) not-quite-1-year-old pup. ODS is in tears, worried his dog is going to die (the younger one). He came in at that part of the video...
