We have three small dogs & in the last couple of days they have been making this odd coughing sound. The puppy does it more often then the older dogs too. We're a little worried about the little one but everyone is still eating, drinking & seems to be healthy. If it is Kennel cough do I have to go to the vet or do we wait it out? I keep reading different things on google but know you yorkie moms will have the right answer!
