If we would follow the directions on the regular Frontline, it would cost us $10+ each month per dog. It really adds up if you have several dogs. I know that many of us though do spend $10 a month on toys, clothes, or treats though, so I guess we really don't have our priorities straight.
The health of our "babies" should come first. I guess we figure the clothes and toys will last longer than a month. But. . . I am one for trying to save where I can SAFELY so I can afford to buy the crew the fun things too. Actually my vet is the one that suggested the spray-on Frontline. I did not know it existed. Big savings for me with like 10 dogs to treat each month. So far the bottle has lasted me 4 months and it is still going! The regular Frontline would have been over $400!!! I have tried Bio-spot and it was crap! Left a big greasy spot. There is a new product out called Tri-force (I believe) that is supposed to be as good as Frontline. It is just as expensive too! It has different ingredients. I was told that if Frontline does not work for you anymore, you fleas has built up an immunity for them and should try the new product. (I work part-time at a vet supply place. This is what the vet that owns the place told us. He no longer practices medicine, as he is too busy with the business. I have not asked my vet if he has heard of it or what he thinks, as the spray-on is working great for me now, so why change?)
