Great flea control

Got the Onguard Plus Flea & Tick Spot Treatment for Dogs, 89-132 lbs, 3 Doses 3 month supply for my 3 dogs. I have two german shepherd dogs and one pit mix. The Onguard Plus Flea & Tick Spot Treatment for Dogs, 89-132 lbs, 3 Doses worked on 2 of my 3 dogs. One of my dogs developed a reaction to the Onguard Plus Flea & Tick Spot Treatment for Dogs, 89-132 lbs, 3 Doses. However my other two dogs did not and within a few hours I could tell the Onguard Plus Flea & Tick Spot Treatment for Dogs, 89-132 lbs, 3 Doses was working. My two German Shepard dogs had no fleas the next day. I would definitely recommend the Onguard Plus Flea & Tick Spot Treatment for Dogs, 89-132 lbs, 3 Doses to family and friends.

Flea and ticks

This product consists of 3 applicator tubes with a twist off top that contains a mixture of Fipronil and Methoprene designed to kill fleas, their eggs and larvae, chewing lice and ticks. The solution is applied on the dogs back between the shoulder blades after parting the hair. It is recommended to reapply every 30 days but has been shown to be effective up to 3 months. Both ingredients work well together in reducing unwanted pests on your furbaby and I find this product is suitable to handle our pets needs.

Flea and Tick great for pets

I was looking for a flea and tick solution for my German shepherd dog which he is a big boy and needed to find something that would stay on his skin. This on guard solution is great. Now I wear gloves to protect my hands cause it could irritate your hands. You just cut the tube and put on back of neck all the down the back where they can’t reach to lick. It will dry and don’t gives bath after doing this. Keep away from cats if you have for 24 hours so they try to lick the dog. You do once a month for treatments.

Worked great for my boxer!

I don't often use flea and tick prevention but this year has been brutal. I notice Shelby scratching in the middle of the night. Found a few fleas (any are too many). While I didn't find any ticks I applied this as recommended. It worked very quickly and I've noticed she is not scratching. I seriously hate ticks and take great comfort from knowing that this product prevents them and rids the dogs of them as well as fleas (years ago during a horrible season I actually found one on my neck!). I read up on the reviews and I'm very confident that this is going to be the product my dogs will be using!

Really works!

This is super fast and easy to apply. I just drop it on my big boy Duke and I'm done. I use to try to give him oral flea medication but he never wanted to take it. This really solved my issues. The drops are super convenient. I have seen absolutely no fleas this past month since he started on this brand. He does not seem to have any irritation or issues from using the product. The bottom line is that it keeps fleas off of him and out of my house. It is a great, effective product. I do recommend.

So far so Good!

I live In Tennessee the fleas and ticks are terrible here! I have a huge black lab mix name Watson. A shoutout for him! I have been using on guard plus tropical treatment on him for 2 months. It works great! I have not seen a tick or flea on him since using! One tube lasts 1 month for protection. 3 tubes per package. Easy to apply just squeeze a tube between the shoulder blades. I will continue to purchase because I see results on my flea problem. I am very satisfied with onguard flea and tick prevention.

Works great

I got the Ongaurd Plus Flea and Tick spot treatment for dogs size 89 to 142lbs, I used it on my husky mixes and it was easy to put on them and works great, they started itching and their old medicine started wearing off so I used the ongaurd and it started working not long after application and lasted longer than their old medicine.

Easy to use.

I have used chewable, collar type, and drops for flea and tick prevention in the past and currently. I am going to use this spot treatment and see how well it works. I have yet to use it. My pup currently has a 6 month collar on that has a couple months of use left. I will update after use.

Unlike other treatments I have tried in the past, this one continues to repel fleas and ticks for a full month. It gives me peace of mind knowing that my furry friend is protected for an extended period of time. Furthermore, I have noticed a significant decrease in my dog's itching and scratching since using this product. It seems to soothe any irritation caused by the pests and keeps my dog comfortable and happy. It's wonderful to see my pet relieved from the discomfort of flea and tick bites. Finally, the affordability of Onguard Plus is another reason why I highly recommend this product. It offers exceptional value for money compared to other treatments on the market. The fact that it is both effective and budget-friendly makes it a no-brainer for any dog owner. In conclusion, Onguard Plus Flea & Tick Spot Treatment for Dogs is a game-changer.

Really Works

We have the most beautiful Newfoundland girl. She has a super deep thick coat which we have trimmed from time to time. She loves her weekly Sunday hike with her Dad. Three or four miles throught the woods. But the ticks just love getting into her coat. I gave the Onguard Plus Flea and Tack Treatment a try. She isn't really crazy with the application but if one per distracts her, the process is finished before she knows what happened. She went on a couple weeks of mega hikes. Today I took her for mega bath. It is a miracle, NO TICKS. Our Newfie girl is 105-110 lbs so make sure you get the product appropriately sized. I am so happy to find this.
