I too was concerned over the size of the Heartgard because I had always used Interceptor. My vet told me not to break or half the Heartgard because it did not have that much in them to hurt them and it would not distrubute the meds correctly. I do break up little Rocky's because he is so little. I don't want him to get choked. As long as they take all of it, I can't see it would hurt. |
