Good option for owners of extra-large dogs who want a three-month supply. My dog falls within the 89–132 lb range, and using the correct dose was uncomplicated. The product arrived well packaged and each treatment was clearly separated.

S
Sophie

I bought NEXTSTAR for my 120 lb dog after looking for a treatment that covered his weight range. The packaging is practical and the doses are easy to handle. I particularly like having several months supplied together because it makes keeping track of his treatment schedule easier.

M
Martin

This has been easy to add to our dog’s regular care routine. The individual doses are neatly packaged and the instructions were simple enough to follow. My dog is quite active and spends a lot of time outdoors, so consistent flea and tick protection is important for us.

R
Rebecca

The main thing I like about this NEXTSTAR treatment is the value of getting three months in one pack. With a 100 lb dog, finding the correct size matters, so I appreciated having a product specifically for X Large dogs.

D
Daniel

I’ve been using NEXTSTAR for my large dog and the three-month supply is really convenient. The applicators are straightforward to use, and I like not having to remember to reorder every few weeks.

This product exceeded my expectations. The liquid applied cleanly without dripping everywhere and my dog acted completely normal afterward. I especially appreciate that it's formulated for larger breeds because dosing can sometimes be confusing with other brands.

P
Patrick

I appreciate that this formula is intended for extra large breeds because many products don't cover my dog's weight range. The instructions were simple, and the medication dried fairly quickly. My dog remained active with no visible irritation.

J
Joshua

The treatment worked reasonably well for my 90 pound Boxer. Fleas were gone after about a week, but I expected a little faster result. Still, it kept my dog protected afterward and I like having enough doses for three months.

A
Amanda

I've used several flea and tick products over the years and this one is among the easiest. The applicator is designed well, making it simple to use without creating a mess. My dog didn't experience any discomfort.

H
Henderson

My Saint Bernard is difficult to manage during grooming, so I appreciated how quickly this treatment could be applied. There wasn't any strong odor and the liquid spread easily between the shoulder blades.

B
Brooks

This treatment has been decent overall. It reduced the flea problem significantly, although I noticed a couple of ticks after a camping trip. That said, it still performed better than another brand I tried recently.

R
Ramirez

I was looking for a more affordable flea treatment without sacrificing quality and this one met my expectations. It worked well on my Mastiff and didn't cause any skin irritation. The instructions were clear, making the application process simple even for a first time buyer.

C
Collins

My German Shepherd weighs around 110 pounds, so I needed something made specifically for larger dogs. NEXTSTAR was easy to apply and my dog didn't seem bothered by it. I noticed fewer ticks after our weekend hikes.

M
Morrison

I have a 95-pound Labrador who spends a lot of time outdoors and this treatment has been very reliable. The application was quick, and I didn't notice any greasy residue after it dried. Within a couple of days, I stopped seeing fleas completely.

D
Derek Lawson

I switched to NEXTSTAR after trying another brand, and I'm pleased with the results. It has kept my large dog protected during camping trips.

N

The monthly application is quick and hassle-free. My dog didn't have any skin irritation, and the product performed exactly as expected.

I have a 105-lb Rottweiler, and this treatment has been very dependable. We spend a lot of time outside, and I haven't noticed any fleas or ticks since using it.
