i've got a question about fleas. my friend has a pug that got into some fleas really bad when the were moving (stayed at her bf house for a few days in the country) anyways she got them off the dog (or so she thought) and since i thought stormie didn't have fleas anymore i took nala over so they could play boy was that a bad mistake. when we got home i bet i got 10 fleas off nala. thank goodness she had been to the groomer that day and got frontlined! my question is this, how can she get them out of her hosue cause aparently that's where they are. i was so mad when i got nala home. i could not believe how many fleas she got on her within a 30 minute time frame. she is one of those people that thinks that she is always right and you are wrong and she tried to tell me that nala got them from being outside not in her house but nala was only outside for 5 min and she has no grass or anything in her yard, just dirt, lol. i doubt nala can get 10-15fleas from being around dirt for 5 min. so is there any other method of getting rid of fleas besides fleas bombs??
