fleas?

Reuben mine are on concrete and I can bet u the world that when it comes to fleas on my dogs I go crazy I hate to watch a dog in the woods run ten feet scratch his NUTTZ then go 50 yards and do the same over and over can't stand a owner that don't change there water clean there pens every day and I don't know what the heck has changed but when I first used it it freakin killed every flea that even thought about biting them and now it seems like there is always that 1-5 that can do what ever a flea dose and nothen bothers them and I can go
Get Adams flea spray and kill the number 2 out the for a few months and same thing happens there but hell maybe it's just cuz I'm anal about fleas so I see little stuff idk
