5 Customer Questions


I have 2 cats is this toxic to them if they run up against the dogs? I know there are not made for cats .

Answer by ChewyMar 31, 2022
This collar is not for use directly on a cat however, it may be used on a dog who lives in the same household.

How long does it take for the collar to become effective? For example, does the collar have to be worn for a minimum of 24 hours before it will prevent pests?

Answer by ChewyJun 04, 2022
This collar starts becoming effective within 24 hours of application.

Do you have to stretch the collar to activate it?

Answer by ChewyMay 11, 2022
This collar does not need to be stretched before use.

Will this fit an adult German shepherd

Answer by ChewyMar 15, 2022
This collar is one size fits all. Each collar is 26 inches long and can be used on dogs with a neck diameter of up to 24 inches. For dogs with a smaller neck, simply trim the collar to size.

Good smelling collars

Whenever I buy flea and tick collars, I’m always afraid that they will stink, but they did not. They smell pretty good.!

Works well

We usually have a major tick problem where I live. I’ve tried different brands but some are very expensive. This was reasonably priced and I tried it last year

We usually have a major tick problem where I live. I’ve tried different brands but some are very expensive. This was reasonably priced and I tried it last year. Got it again this year for my 4 dogs (3 medium to large and one small) and it works great. Haven’t seen a tick or flea this year!

I received my collars on July 15. I placed one on each dog, but the scratching never stopped. I gave them capstar the first day. I put the collars on and wound up having to give another capstar a week later because they still had fleas. Now here it is almost 2 weeks later and they are still scratching, and I am still seeing fleas. I originally put these on a subscription, but I will be canceling and going back to Seresto

I bought this for my Wobbles, and it's garbage, I went with a cheaper brand than the usual one seresto, finances are tight, but my dog still itching constantly with this brand. Serezto he didn't itch or scratch for an entire year. Highly dissatisfied in the product, I Love Chewy products, never complain, but this one hurts. I would not recommend this flea collar.
