[BabieChloe]

I was going to use frontline for fleas but there isn't much of a flea problem where I am.. and I researched some very bad things about frontline ( and other topical flea preventatives) - so that's out. Heartworm, however, I think I rather prevent because I personally get bit by many mosquitos in the summer which means Chloe has the same chance of getting bit as I do.

The problem is I can't decide between heartgard and sentinel. I don't really want to apply a topical so that leaves these 2. Which has been around longest? Chloe is under 3lbs so I'm having difficulty making myself give her heartgard which can be used for a 25lb dog vs sentinel which is much closer to her weight 2-5lbs. What I don't like about sentinel though is that it has a dewormer and I feel that's unnecessary.. or is it?

My main concern is the the huge weight difference in heartgard which is why I haven't given it. On the other hand, sentinel is a "combined" med but it isn't really any good for fleas? If I'm going to give a combined med I want it to at least work well.. so I can't decide how to weigh the pros and cons here. I need some opinions and what your babies are using. I'm scared if I give the 25lb dosage to my 2.5lb baby that she might get upset stomach.

Advice?
