Does the heartworm medicine make your babies sick? I have Nolee on Advantage multi. The day of application, he is crazy. Doesn't know what to do with himself. He just keeps walking in circles. Then just will go lay around. All of that day is spent mostly laying around. He is just not himself. Is this normal??? I have been using this for 6 months. It only is the first day. After that he is fine!
