Liberty 50 Spot-On for Dogs Review
Manufactured by Star Horse, Liberty 50 Spot On for Dogs is flea and tick treatment that claims to also eliminate lice, mites, and mosquitoes.
Star Horse claims that their product, which consists of 50% Permethrin and 1.2% Pyriproxyfen, is “one of the safest pest control products on the market.” According to them it outperforms competitors by killing flea eggs and larvae for up to eight weeks and outlasts them with two additional weeks of tick protection. It also claims to be able to kill lice and mites unlike its competitors. Well, at least that is what Star Horse claims Liberty 50 Spot-On can do. Actual reviews are hard to come by.
However, while there aren’t many reviews for Liberty 50 Spot-On, there are plenty of reviews on Permethrin, the active ingredient found in this product. Unfortunately, the Environmental Protection Agency is more closely regulating over-the-counter pesticides such as Liberty 50 due to an alarming increase in flea and tick control related deaths and illnesses. Cats are highly intolerant to Permethrin, and the company makes it clear that Liberty 50 should not be used on cats. Despite the clear “no cat” warning, they fail to mention that the National Resources Defense Council implicates Permethrin as a carcinogenic agent with the ability to disrupt the endocrine system in humans. It is also a possible contributor to asthma and alleries. The EPA also points to negative side effects in pets such as skin irritation, loss of appetite, and vomiting.
Moreover, reviews over BioSpot, a flea and tick treatment that contains 45% Permethrin, validate the EPA’s concerns. Yes, these reviews are not specifcially on Liberty 50, but they illustrate Permethrin’s side effects and indict Liberty 50′s safety claim. Many reviewers indicate that upon first use, their pets appeared to be fine, with only a slight drop in appetite or mood; however, after several months of treatments, several pets began refusing to eat for long periods of time, vomiting, and itching. Many reviews also attest to an irritating skin rash immediately upon application of the product. Several reviewers complained of its failure to work for more than a few weeks.
Permethrim is a pesticide proven to have ill effects on humans and animals, and Liberty 50 Spot On for Dogs contains more Permthrim than other medications. It may by half the price, but the savings are not worth the harm.





My 2 Pomeranians acquired lice from who knows where and I used the Liberty 50 on them and I had amazing results… My male had bald spots and sores under his thick Winter coat. I didn’t realize until I gave him a bath what was going on.. I bought the drops, bathed tue dogs in regular oatmeal shampoo and then applied the drops.. After 30 days and warmer weather I went to shave them and start all over. All the bald spots were healed and had all new fur regrowth. They didn’t have 1 flea on them either.. This stuff works for sure.. Just apply tue right weight dosage and you should be fine.. Toy dogs are usually super sensitive to anything and my 2 Poms did just fine..
I tried Liberty 50 flea & tick treatment bought from my groomed an it sucks. Made my dog sick for about 2 days an it dose not work. The dog is still getting fleas an I have pulled a tick off of her an she has only had the product on for 9 days an I an going to have to find a way to control her fleas till its safe to put a new product on her. Going to vet this time
Liberty 50 Plus IGR Spot-on for dogs. I have been using this product for 6 months, every first of the month my dogs go off not eating. The cairn terrier is being ate alive with fleas!! fleas are also on the other 2 dogs, 1 siberian huskie and lab mix. As for ticks I am always finding ticks on all 3 of them not as many but still ticks. Going to my vet to see what can be done for the dogs. The cairn terrier also has raw sores from scratching her back so much, like a rash. And she is pulling out her hair on her back from all the irritation.
We use Liberty 50 at our kennels with great results. Most of our dogs have been neglected and we have no history on them. We have had a many come in covered in ticks and fleas. After 48 hrs of having the Liberty 50 on, most if not all the ticks were dead and literally falling off. The fleas are not a problem either. Because of the multiple dogs it’s so important to prevent any kind of infestations and the Liberty is great.
My children went in the woods and took our poodle. They got into an infestation of ticks. She already had this product on but it was due for a second treatment, so I went applied her monthly dose a day or two early. It did not work. We though she was OK. I pulled 60 ticks off of her a day later. (I counted them) they were the size of a pin head, but they were not dead. Product does not work and the risk does not out weigh the benefits. I will not waste my money on this product again.
I have a 2 year old Yorkie/Lauchen mix and I purchased Liberty 50 as a preventitive not just against Fleas, but against ticks & mosquitos too. After one dose my poor dog was in agony itching the sight where I applied the product. That night he kept my husband and I awake all night with his itching and restlessness. He sleeps with us and he couldn’t lie still all night. I would never recommend this product to anyone since it has such horrible side effects.
i have tried it out two different times on all 4 of my dogs with no luck did not work….now i’m trying to figure out how long i have to wait until i can apply frontline…..
I put liberty 50 on my small dog. She ended up getting a hot spot from this medication and she had to have surgery. It could have killed her. The surgery cost $105 and she is in severe pain. I would NEVER recommend this product to anyone and I am going to let everyone I know about how dangerous this product is!
this stuff does NOT work! I have a small pomeranian mix and she has fleas, I went to a local store and saw what liberty 50 claims to do. Now 5 days later theres not a difference and she’s still being attacked like crazy by fleas. $18 for a product that doesnt work and i’m now stuck waiting 25 more days to apply something else. To add to it I went to their website and there’s no way to contact them to make a complaint or get a refund…figures what a waste of time and my poor dog is miserable. How is it fair that a product can claim to work and I purchase it, follow directions, apply it and get no relief for my dog. I hope the company learns compassion and learns that putting a product out there to prevent animal diseases infection and discomfort from the pests and it not being capable of doing that at all I feel should be punishable under animal cruelty. People who choose not to treat their pets and let them stay flea and pest infested can get charged for animal abuse and those of us who want to stop or prevent an infestation rely on companies to be truthful and buy their product to help our animals just to find that we have to wait now even longer to have a fix for our furry friends, Im highly disappointed and really upset my dog is going to be this uncomfortable for more than 3 weeks because of this company claiming to have a great product.
tried frontline on all my neighbors cats, my cats neighbors schnauzer and my english mastiff. 3 days later my mastiff has more fleas each cat has about 100 fleas and the schnauzer was the same. Flea dipped and bathed them all which resulted in a trip to the ER from a cat bite. Got liberty for the dogs and had amazing results..no more fleas for 6 weeks. Also rescued a jack russell/fiest covered in fleas and ticks. I removed the ones I saw on night one..then put liberty on here after her bath the next day I found 3 dead ticks in here ear and one almost dead in the other ear. Still haven’t tried advantage here (just moved from oregon to tennessee) which starts tomorrow because the mastiff made friends with 2 kittens and I don’t want to risk their health but all in all liberty 50 worked great for me!
please excuse the spelling and grammar errors in my post. its very late :)
