That is when my puppy started to do it. He will run laps and stop and hack hack. Sometimes one quick hack and others times 3 quick hacks. In the summer he did it a few times a day. In the winter every few weeks. I am still trying to figure it out because I have only had him for 9 months now. No rhyme or reason. Sometimes when running, Sometimes when chewing his toys or sometimes when just walking across the room but mostly when playing. |
