Rated 5 out of 5by Sentinel Works for FleasI have been using Sentinel for years for my pugs and have not had any problems with fleas. Two years ago I switched to Seresto flea collar that was suppose to work for 8 months and within 5 months all my dogs had fleas. I have switched back to Sentinel and also use Frontline Plus during the summer months. 06/08/2018
