What do you use for natural heartworm prevention? How often do you give it and how much? Is it as effective as meds like Sentinel? My breeder is against giving her dogs meds for heartworm, fleas...etc. because of the side effects. She doesn't think they need them if they're housedogs. I was told by her that if dogs get heartworm though, nothing can be done so that's why I'm currently giving Angel Sentinel once a month. I'm afraid of taking the risk of not treating her w/ meds. I do wonder if the pill is causing her skin problems. She wasn't scratching her chin/jaw when I first took her home in June, but the Sentinel pill is the only thing that's ongoing since 2 days after I brought her home when I went to the vet's for a checkup and got the meds. I read an article that heartworm meds contain an insecticide, and the more you give it to your dogs, the more effects it can have on them, such as skin allergies.
Here's the article:
