About 3 months ago, I got a puppy. Shortly after that, I began experiencing a sore throat off and on for about 2 weeks (I think); then I had a daily dry cough. About 1 week after having the daily dry cough, I went to my doctor and he said that it was allergic bronchitis and I should take Claritin. Within about 1 week after that, I began coughing up phlegm;which has continued ever since. The coughing/phlegm is not constant. But every day, usually about the same time of day, I cough/cough up phlegm (sometimes) and experience the need to constantly clear my throat. This last for about a couple hours and then I am fine for the rest of the day. (For a couple weeks, I did also have a coughing session for a couple hours in the late evening - this was not associated with the need to cough up phlegm; it was just a dry cough which seemed to make me wheeze slightly. I have had asthma since I was 3 years old; but it is usually never a problem. I have never had to be hospitalized for it and I do not need to have an inhaler with me. Some wheezing usually occurs when I am sick with something else; otherwise, my asthma is not a problem.
My question: is it possible that a dog allergy can cause these type of symptoms which I only experience for a short period of every day? (Note: when I experience the daily coughing and phlegm, it usually occurs in late morning hours when I am not around the puppy.)
