Seresto Flea Collar Warning

[Polestar50]

My dog (collie cross) has been wearing her Seresto flea collar for approximately three months. No problems at first but she has just developed an awful reaction.

Bright red/pink skin and small lesions all around her neck where the collar sits.
Obviously collar was immediately removed and she's been to the vet. They said it is an unusual reaction (usually adverse reactions happen soon after collar has been put on) and the redness should go down now collar is off.

It's a shame as it was working brilliantly. No fleas or ticks since wearing the collar.

I am just wondering how common this reaction is. And also to warm others to keep a close eye if their dog has a Seresto collar.

Has anyone else had problems using this product?

Forgot to add photos

The seresto collar just didn't work very well for us but we had no reaction. That looks very painful

Yep my border collie has had the same sort of thing, he's on his second one, no reaction for over 12 months but this one has been on for 4 months, I took it off to Bath him and found he had a red bit on his neck and a burn like lesion. Vet said this can happen and not unusual in collie breeds. So won't be using in the future.
