What to Look for in Flea Shampoos

“I would suggest one marked for use in cats and dogs to control accidental cat toxicity problems,” says Lisa Tanner, DMV, a veterinarian established in Alpharetta, Georgia. “I would also advise reading the tips carefully to assure they can be fully followed.”


There are two sorts of flea shampoos: synthetic chemicals and those that utilize essential oils. If you like more natural products, look for essential oils, but instructions with ingredients like pyrethrins or permethrin are more powerful and last longer. Pyrethrins are emanated from the chrysanthemum plant, and permethrin is the synthetic version. Pets can have allergic responses to anything, so speak to your vet for recommendations.


Most of the flea shampoos we examined told us they were safe for puppies 12 weeks and up, but inspect the label. Please don’t utilize a product on a younger puppy because it could be too harsh on developing and growing youthful skin.
