Best Flea and Tick Shampoo

Did a lot of research on the best flea and tick shampoo for my new pup of 9 weeks old. Australian Shepherd. Didn't want to harm him in any way. Everything I read says that this one of the best and is priced right. Used it and seems to work great, leaves nice and soft fur, and didn't bother him in any way whatsoever. Highly recommend.

Only shampoo that seems to work!

Last year we had a major flea issue at our home and nothing seemed to work but this! We bombed the house, I washed and dipped our dogs in several different products and nothing seemed to help. This stuff was a life saver, it does the trick!

Soothes Sensitive Skin

I used this on my furry baby because she was nonstop scratching. I was happy to see the fleas falling off dead. I love the oatmeal, which is a plus because my furry baby has sensitive skin. Now she is so relaxed. Will purchase again.

Works well for the Pugs

Literally whitens up the Pugs, makes them feel clean and joyous. Literally, they run around with smiles after their bath. Offers flea protection. I put my dogs in the tub, wet them down, rub this in and let it sit on them for around three minutes before fully rinsing it off with lukewarm water. Dab them dry with a towel, and done.

Good for lesser flea infestations, smells good, helps with itching.

This shampoo really works. I used to live in an apartment that was infested with fleas -the complex not mine specifically - and this shampoo really helped during the spring season. It started killing them almost immediately, and my dog was feeling better within a week. The shampoo also smells really nice. Just make sure you follow the instructions, and if there is a heavy infestation to use a vet prescribed medication. This one will only help with minor ones. It's also very affordable too and smells nice.

Effective flea and tick shampoo

Finally found something that works well for my dog. The formula is powerful and really helps with fleas and ticks. I love it because it leaves my pet smelling fresh with the tropical breeze scent. It's great for keeping my dog clean and pest-free, and the 18oz size lasts quite a while. Definitely a product I'll keep using.

Amazing Shampoo

This shampoo works amazingly well. Our dog star lost most of her hair on her back due her itching and biting. First we were told it was allergies and spent ridiculous amounts for vet shots that gave her little to no relieve. It was the same with the vitamins and the creams. However, once I started using Pet Armor Shampoo just once a week, I noticed amazing results. Within 2 weeks her hair grew back and has remained full ever since.

It Worked For the First Wash

My mini schnauzers just turned 1 and have NEVER had fleas, ticks, or a preventative outside of regular grooming and wipe downs in between baths. I’ve always bathed them once a week and never had any issues with pests until RECENTLY.I used this after I noticed a flea on one of my dogs while brushing him. It definitely kills on contact and I saw them in the water when I rinsed. I also had suds in my hand from bathing him and watched one die immediately. The smell is nice and kept their fur soft. I bathed both of them twice and let it sit for 5 minutes each time. I also cut their fur down to keep an eye on them. So far the itching and scratching hasn’t stopped but it’s not as excessive nor are they losing fur. My whole house has been treated so I think it’s just a waiting game now.I’m skeptical about it working for 30 days so I’m just gonna bathe them weekly as a preventative.

Kills fleas

I purchased this due to my cat getting out of the house and then coming back into the house, loaded with fleas and giving fleas to dogs. Bath went good, this product kills on contact and I watched fleas jumping off but landing in the bath water. I’m not sure about repellent but after a few hours my dogs/ cat have no itching. The bottle says seven day repellent, but I’ll probably do a mid week bath and also wash all bedding. I would buy again.

Impressive Results & Refreshing Scent

There are quite a few reasons why I love this product. Firstly, it cleans and conditions the coat of my dog perfectly. The generous 18 fl. oz. bottle size is another advantage. I appreciate that it's safe to use on puppies as well, making it suitable for all my dogs. The application process is super easy. Overall, I highly recommend it

Kills Flea Eggs and Sooths Skin

Our two year old Australian Shepard had a bad flea infestation to the point where he was getting bald spots on his rear from biting hair. We tried drops, natural spray repellants, but neither worked. We then bought PetArmor shampoo and followed the directions by lathering him up all over and letting the shampoo stay on him for about five minutes before rinsing off thoroughly. For the few days I flea combed him, removing about 10-20 fleas each time. After about a week, I didn't find any more fleas. I'm convinced that the PetArmor shampoo killed or removed any remaining flea eggs, plus soothed the rashes caused by the bites. It's been about a month since the initial shampoo and his hair is growing back. I would definitely recommend PetArmor shampoo.
