Yes, Amoxicilln is an antibiotic used to treat Kennel cough.

If your dog shows symptoms of kennel cough the first thing you need to do is isolate him from other pets you may have or be in contact with. Go to the vet A.S.A.P. The'll take it from here.

Kennel cough is contagious, the dogs should be kept separate until cured

No. Dogs cannot get The flu but they do get the kennel cough. Kennel cough is basiclly a doggie cold/flu. Hope this helped:)

Amoxicillin does not help with kennel cough. Go see your veterinarian.
