It's been about a month since their last dose of flea treatment. The vet gave me the stuff to put on the backs of their necks. The last 2 times when the 30 days the meds were supposed to be effective were up, they already had a few fleas - not many, but some. This time, I haven't seen any sign of fleas. Will they need flea treatment anyway? And the vet's assistant who gave me the last 2 doses of flea treatment said I should have them wormed one more time just in case since they had a few fleas. Their vet's office is about 30 miles away so I was wondering if Wal*Mart would have good flea and worm meds and what would be the best to buy. I don't see the point in driving all the way to the office if I don't have to because there's nothing wrong with them.
