The "too many dogs get heartworm while on it" is hearsay right now.
The other part is Googlable.
There are about 36 reported deaths from Revolution a year and only 6 with Heartgard. If there were more dogs on Revolution, those statistics would make sense, but my guess is that more dogs are on Heartgard because it is older and well known...
A good way to find out is to contact the FDA.
