ShieldTec Flea and Tick Collar for Dogs, 12 Weeks of Age or Older, One Size Fits All, 6 Months Protection

Within 24 hours after putting the collar on my dog she started acting disoriented and lethargic. The only change was the collar. Once we removed the collar she got back to acting like her old self within hours. going back to Seresto.

Have used this collar for several years.. works great. My dogs play pretty rough with each other but the collars stay on.

since my dog is a house dog. i wanted to find something that would not bother anyone who was to rub him. these has worked great. as far no flies or ticks. summer is almost here an it will get back. i think this is a winner

Used these last year and they work great. so I'm using them again!

I have a small terrier and despite saying one size fits all, it is very loose on the smallest option. Other than the size, I am very satisfied. We had to find a new brand, as the last collar gave my dog a rash. We have no issue with this collar.

Excellent for my dogs.Fit both Medium and Large both. They are very active and the extra secure closure is great. I have no worries about it coming off accidentally.

Can't really say that this collar worked very well. Will not purchase again.

Got Rid of fleas and my dogs itching. I recxomend
