The non-annulal treatment is ludicrous in my mind. Treating only for the months they are supposedly active in your region.<---it's seriously faulty, especially with indoor animals.
I've seen and understand the "treatment map" however, how do you know a dog infected with heart worm didn't just come in the are of your dog from another location?
How you you know someone didn't step on an egg and then leave it in the grocery store and then you stepped on it and it survived in the warm groove of your shoe before falling off your shoe back in your home and infecting your dog?
In a day and age when parasites travel from region to region because we travel from region to region so much and even in an environment where something shouldn't be active, alive or survive-it will now and the risk is just too great.
We still vaccinate our children again disease we haven't had in this country in a hundred years (liberally stating that fact quite loosely) because there are corners of the Earth where it survives and someone traveled there and brought it here to 'your or our' small town from the other corner of the Earth. |
