hi pit luv, Jeff,
this is a great question and not many people ask!! this is what I was told by a bio chemist. Give a full dose of heartworm med starting in March.. wait 3 months and give it again, wait 3 more months and give it a 3rd time and after the hard frost wait until March again. As for the stuff for ticks and fleas.. My experience is don’t use it. I am a professional trainer.. I saw my friend put it on his puppy and the dog got seizures. It is fairly uncommon I think but I think dogs get other sicknesses from this stuff it goes right into their nervous system. If it tells us not to touch it WHY would you give it to your dog?? It took this guy 2 years to listen to me and he stopped it and slowly his dog got much better. I would use something natural and put a lot of it on I make this up 1 cup water
2 Cups white vinegar
2 Teaspoons of a vegetable oil
2 Teaspoons, lemon or citrus oil or peppermint oil
mix it all together and use as a spray
It works well I know that the peppermint oil keeps mice absolutely out of my barn they hate it.
