permethrein 10% just mix accordimg to label 1 oz to a gal water wet a rag and wipe the pups down then use the rest on the bitch . and wipe the floor down where the pups lay . fleas bring tape worms with them and the pups don't need that . this is safe i just did my bulldog pups . they was born on the 28th . it is safe and affective .
x2 on the permythrin 10%...safe to use and I buy it at TSC...
