My puppy is a mixed Bighon and Poodle. 10 weeks, Once in a while she will start to breath in and out very hard and her entire body lurges forward and back. Her heart rate also goes way up. It doesn't seem to happen at any given time, She runs and plays with no problem. Sometimes she'll be sitting and it starts. Lasts about 10 to 15 seconds. shes alert when this happens and shows no after affects. I have seen it happen after she eats. Any Idea?
