Well, I am not taking any chances anymore either!!! I am glad my two Shih Tzu's tested negative and I have started them on their 6month supply of Heartgard, but I am going to go back in and purchase for year round. Is there a difference in the pill? I keep hearing about the (PILL) for Heart Worms and we are given Heartgard which is a chunk of ? not a pill, but maybe this is what everyone refers to as a Pill. |
