I have been told that the little scabs on the back of my dogs neck are 'hives'?? they are small raised lumps, with small areas of dry skin around them. I have been told to treat him with Piriton and benzyl benzoate, and it seems to be working. Where have they come from and is there anyway/supplement he can have to prevent this in future.

Thanks

Hives are a symptom of an allergy :)

Is there anything it is more likely to be? someone said grass seeds although he hasn't had problems before!!

It could be anything ..the thing about an allergy is that a dog (or a person) can suddenly become allergic to something that they have been okay with previously OR can show an allergy when they come across something for the first time :)

Could be harvest mites, I've got a few bites myself :) but thankfully it is coming to the end of their season.  They are often treated with benzyl benzoate but if you use something like a couple of squirts of Nuvan Top or Frontline every couple of weeks over the feet area it should prevent them climbing up the dog in the first place.

Thanks very much for the advice, most welcome
