Sophie spent the entire night gagging or coughing and trying to throw up, but nothing came out. I gave her some honey in case her throat was irritated which she really liked and it seems to have calmed the hacking cough for the time being. She was given kennel cough vaccine up her nose when she got her shots last week. So I was wondering if this is a case of kennel cough, allergies or something serious I should take her back to the vet for. Thought at first she had swallowed something she shouldn't have. She isn't running a temp and I am at a loss what to do. Thanks
