Are some dogs more prone to kennel cough than others? Hoosier woke up this morning with a little snot, mostly clear. When I came home at lunch and this evening, I noticed he was a little sluggish. Then in happened. I was running around the yard him , then HACK HACK HACK! I can't tell you how pissed I am! This will be the third time in the 5 months that we've had him. He's been vaccinated and just don't understand why this keeps happening. What's the point of vaccinations? We have some words for the day care we've taken him too and their "screening", but this is rediculous. Is there something else I should know about succeptibility to kennel cough?
