Advantus Dog Advantus Chewable Flea Treatment for Dogs 4-22 lbs. | 30 ct.

It’s inexpensive, yet effective. It’s also gentle. For dogs with lots of fleas and eggs you may need to give your dog one everyday for a few weeks. I only give my dog one every three to four weeks, but he never had fleas bad. My dog is very picky and if I break each one into pieces he eats it right up. He has never had any sort of negative reaction.

Works well, just like advertised

One of my dog had a bolding spot due to fleas and after I gave it some of this not only did it the fleas spotted she started growing hair again

All pet owners know that once summer rolls around, fleas become a bit more of a problem. I noticed my dogs had a couple of fleas on them a week ago so I decided to go ahead and order these for them. I gave them a bath first and then fed them the chewies, and the next day the fleas were gone and I haven't seen any on them since, so the product definitely did the job I wanted it to.

Seems to only work for about 8-12 hours.
