Martha our dog has a sickness called kennel cough! It is a highly contagious illness so we have to keep her inside at all times and she is always coughing when she gets exited and sometimes we even find blood that Martha had coughed up! She is just lying her bed a lot and only gets up to greet people into the house. I hope it clears up very quickly! The vet said it clears up on its own but like I said I hope it does ! It was getting better but then got much worse.please get better soon Martha!
