Yes, kennel cough in dogs is highly contagious to other dogs.
Well you can not cure a dogs cough but if it is really real then you need to see a vet and they can help you.
yes, bigger dogs need more water to stay hydrated than smaller dogs.
Sometimes they will get a bit of water in their air way if the drink quickly and this will cause them to cough as they clear the water out. If it is happening every time a dog drinks it could be something more and the dog should be taken to the vet.
Yes
No. Dogs cannot get The flu but they do get the kennel cough. Kennel cough is basiclly a doggie cold/flu. Hope this helped:)
Dogs puff out their cheeks when they need to cough but it doesn't come out right or when they "burp" or "hiccup", except it's a little different when they do it. I don't know how they do it. Like we do?
Yes, kennel cough is highly contagious to other dogs. It is typically spread through the air or direct contact with infected dogs.
