I use something like frontline on my dogs at the first of every month but I'll put some seven on em toward the end of the month if the other stuff is wearing off and they need something to get them through. That rarely happens.
Thanks for all y'all help, it looks like it is working.......
get you some bayer tree and shrub from lowes or home depot...or you can buy the ortho max tree and shrub...make sure it doesn't have the fertilizer in it and then pour 15 cc's over your dogs top line and rub it in onto the skin...the amount I am talking about works for a 40-60 pound dog...just make sure you buy the one that has the 1.47% active ingredient...should be right under 20 bucks but will last you a long time...you can use it on your dogs once a month but my dogs go at least 6 months without fleas...make sure to wear rubber gloves...
