Heartworm wasn't big in CA for years, so most people did't test or have their dogs on prevention. It's unfortunately becoming much more common, so we're now having to include that in normal checkups like a lot of other states, but to be honest most don't even think about it hear.

Well it's still not the same one I've seen before (but it was a couple/few years ago, maybe it doesn't even exist anymore???) but it's better than the other ones I can find. Thanks a bunch!!
It is very similar to the one I'm looking for but it's not as defined. The one I am looking for has all that info but it also displays more detail about how many cases are found in different sections of each state, not just the whole state in general.
