I did not know that Heartgard had been changed. My girls have been on it for quite awhile with no difficulties.
A couple of years ago my Vivi got into two packs of Heartgard and I about had a heart attack when I got home and found the boxes opened. She ate nine of them. I called the emergency vet and they had me call the dog poison control. Turns out that she would have had to have eaten 12 to have any poor effects. If Heartgard had been changed, of course this could all be different now. |
