Hello! Our vet recommended we give a monthly dose of Sentinel to our 13-week puppy for preventative care. We live in Seattle and cases of heartworm in this region are low, as are ticks/mosquitos. However, being in a city with a high dog population, fleas are not uncommon. We also intend to hike and swim with her quite a bit, so she'll likely encounter mosquitos, although our mosquitos aren't nearly as bad as they are in the Midwest or East Coast. We're on the fence about whether Sentinel is the right medication for her, or if we should consider other options. Recommendations are welcome. Thank you!
