I feel more safe using Heartgard because it's been around longer. My yorkie is 3 pounds and I give her the 1-25 lbs tablet but I do think Sentinel is probably better for little dog dosages. I just don't give Sentinel because it also has de-worming and I rather not give extra things that I don't need. You probably shouldn't split the Iverhart because the piece you leave can actually have the medication but you wouldn't be able to know. If you want the smaller dosage you can try Sentinel.
As lovetodream said, PLEASE don't use Trifexis. It's more expensive but that doesn't mean it's good.. it has caused a lot of deaths. |
