I’m almost embarrassed that I had to order this. I had a slight flea infestation thanks to “Le Dog”. In 30 years of dog & cat ownership I have never had to deal with fleas and ticks. Fast forward to 2023, I’m now living adjacent to a dense wooded area. Stupid me, I thought those expensive monthly chew tablets prescribed by the vet for fleas & ticks took care of just that, fleas and ticks. As they say, ‘it’s complicated’! As a pet owner, I feel like I’ve let them down. Believe it or not, I never saw a flea on my dog, it was found on the indoor cat that never goes outside! My dog is a dachshund/beagle mix so he has a smooth, very dense, tight double undercoat of brown black fur to hide in, but the cat… he has a fine coat of light ginger colored fur so it couldn’t hide and got caught ‘sneaking’ about.Long story short, after a quick call to the vet, all the pets needed capstar administered which would kill fleas immediately BUT not the eggs. Unfortunately, we are talking about giving reluctant 20lb male cats a pill they would rather not have. With one dog and 4 cats in tow we headed to the vet to have the ‘flea killer’ pill administered. Meanwhile, pest control came to bomb the house & spray the yard while on our little day trip to the vet. The next step was washing/sanitizing all beddings & linen and vacuuming the floors with the dog bath last. Since I was already familiar with the Veterinary Formula product line and it being paraben free and no skin reactions on the dog, I ordered their Flea & Tick shampoo. The 16oz bottle guarantees l’ll get more than a couple of baths out of it. I also needed to strike a balance of a reliable brand that was effective in killing fleas, was not harmful or irritate my dog’s sensitivities, and was affordable. This was it. I needed it to kill any adult stragglers, immature fleas or newly hatched fleas that the pill did not. My first “sniff” impression is the shampoo does NOT have a strong chemical odor, but more of a mild citrusy scent (better than what I was expecting). It does a great job of lathering up making it easy to work into the undercoat and reach any fleas living there. There was no skin irritation, burning, or allergy to using the shampoo and it left no residue. It felt more like a sudsy conditioner. I waited closer to 8 minutes before rinsing out the shampoo. That stuff is fantastic! Oh-kay, he didn’t smell as sweet as his oatmeal shampoo BUT… he had “salon soft” and silky fur! It’s actually better than the conditioner I have been using. As for fleas? I may have seen a spec or two in the bathtub. In all likelihood, the dog was used as a flea taxi into the house & cats. Up until now, the indoor cats were not on any flea prevention, but that has changed as well as getting flea combed. As they say, ‘where there is one, there is many’. While the shampoo was effective in killing & removing current fleas on Lucky Lou, it had to be used in conjunction with the other flea prevention treatments above to get ahead of the flea-eggs crazy life-cycle. A second flea bath was given 10 days out as a precaution. Did you know one flea can lay 50 eggs? Worse, one female flea in 60 days can leave you with 20,000 if not treated. -The constant spray, wash, vacuum, of carpet, bedding & linens and the once monthly flea oral & topical treatments now has house & pets “flea-free” for 82 days! I’m also pretty sure the cooler weather has helped to control the yard population as well as planting plenty of mint about. Overall, 5 stars! Neither dog nor cats have fleas! This is my grail of flea shampoo!
