Babe now has a victory patch on his back where he was shaved to receive his very deep tissue (mega-painful) injection for the initial kill-off of the heartworms. His heart is enlarged from the worms and they are also in his lungs. His victory patch is an indication that he is on the way to recovery. For two days he was very sore in those muscles where the injection occurred and he was tired. The first 72 hours is critical and he has had no problems.
The possibility always exists that a worm die-off will cause an embolism or clot if his blood courses through his veins because he is too active. But if he attempts to have fun I just speak to him quietly and he calms right down. He’s a very good patient.
