I'm posting because I've heard some varied opinions on the importance of preventative heartworm medication. Our breeder warned us about vets' tendency to over-medicate/vaccinate dogs and I'm wondering how many of you give your Vs heartworm medication, or have heard dissenting opinions about it. I guess the prevalence of heartworm also depends on the region you're in, and I'm under the impression that it's actually very rare up in my neck of the woods (Toronto), so I'm on the fence about whether I should start Luna on the monthly dose.
Any insight would be appreciated
