This has been a convenient option for my older large dog. I like the fact that the collar provides protection for an extended period without needing a monthly reminder.

E
Emily

Overall, I’m happy with the collar. My dog spends quite a bit of time in the garden and on trails, so having longer-lasting protection is useful. The collar seems durable and has not cracked or stretched after several months.

J
Jason

I was looking for something simple for my Labrador because I often forget when monthly flea treatments are due. This collar has been very easy to use. I just adjusted it to fit and trimmed the extra length.

R
Rachel

The biggest reason I bought this collar was the long protection period. Eight months is much easier for me to manage than keeping track of frequent applications. The collar itself feels lightweight and doesn’t look too bulky on my dog.

I’ve been using this Seresto collar on my large dog for a few months now, and so far it has been very convenient. I like that there’s no need to remember a monthly treatment.

C
Cooper

I’ve been using this collar on my large dog for a few weeks and so far, I’m happy with it. It was easy to put on and adjust, and my dog didn’t seem bothered by wearing it. I also like that I don’t have to remember a monthly flea treatment. The collar feels well made and stays in place during walks and outdoor play.

Oliviabennett

The biggest advantage for me is the convenience. With an active dog, applying treatments every few weeks can be a hassle, so having long-term protection in one collar is helpful. The design is simple and lightweight, and it hasn’t affected my dog’s normal routine. I think the price is reasonable considering the advertised eight-month protection, although I’ll need more time to judge its performance over the full period.

C
Cooper

I bought this collar after dealing with a few flea problems during the warmer months. Putting it on was straightforward, and the adjustable fit worked well for my dog. The material feels sturdy rather than flimsy, which gives me confidence that it will hold up outdoors.

D

Overall, this collar has been convenient and easy to use. My dog spends quite a bit of time in the yard, so I wanted something that wouldn’t require constant reapplication.
