Important Information

Fleas rise to the top of your pet's coat as they die, so consider it a triumph if you start seeing more fleas at first, after treating your pet. If you’re still seeing fleas after application, it may be because your pet has picked up new fleas from the environment, which may include other pets, surfaces and outdoor areas. It may take up to 30 days to break the entire flea life cycle. Additionally, you should also treat sources of new fleas (i.e., carpet, yard, etc.) to ensure complete flea control.

Stops wet Dog smell

I use this shampoo regularly with my 3 dogs and haven't noticed any problems, burns, illnesses. I use because it smells fresh, controls mites, and stops that wet Dog smell when my fur babies play in the water. My mother hates the smell of dogs, but doesn't mind mine visiting because of this shampoo. I also use it preemptively to ward off fleas and mosquitos and it does a great job. We have never had fleas. I am concerned about the negative reports of dogs dying and plan to investigate this further, but I have used this shampoo bi weekly for 7 years and have nothing but good to report. I follow this shampoo with Chi Dog Shampoo and Conditioner. And love the results from both shampoos.

didn't help

I do not recommend this product. My dog has itchy skin and fleas and ticks and this shampoo did nothing to help him. I was very dissatisfied with this product. I will not be buying this product again.

Does the job

Shampoo that does the job! No complaints here, wish the scent was a bit less intense, but it doesn't irritate the skin.

My dog had a adverse reaction to this shampoo.

After her bath she just collapsed on her side and even her bark was weird.. I'm glad I didn't leave it on for the reccomended 5 min. Her adverse reaction really scared me.. From now on I'll just bathe her with Dawn dish soap. I have heard others with this same complaint. I did not purchase this from Chewy

Do not recommend

My dogs had fleas and I washed them several times with this shampoo and my dogs still had fleas on them after. I followed the directions. I left it on for 5 minutes and used a flea comb . Some adult fleas do come off but it does not kill the eggs. My dogs were scratching shortly after being bathed.

Bought this before I realized that it has a reputation for killing dogs and when I researched I found it has multiple lawsuits against it for killing dogs. Disappointed that Chewy would sell this to the unsuspecting public.
