wow thank you all for your replies! I have not tried any other anti histamines yet but that is definately something that I will look into if they have different effects on different dogs as she is currently on the highest dose of piriton. Also can you get the boots brands of steroid over the counter with them being steroid based?

As for the allergy the vet has not taken any blood tests even though I have pushed them to do so, I have now been to two different vets about this condition and both seem to think it is hayfever but I am unsure because of the change of surroundings. I have tried to keep everything as similar to her other house ie cleaning products, food etc because that was what I thought the problem was origionally, however when she first started to suffer it was when we walked on a freshly cut field and the moment she got home she began chewing and so that was why I thought it must be hayfever and the vet seems to think she shows all the signs of severe hayfever. She is also scratching but she has constant fleaing and we mentioned mites to the vet but they didnt seem to think that it was an issue.

I have also bought her a set of boots, which she hates I might add! But they do stop her from getting to her paws untill I leave the house and then when I get back they are off! I have also got her a buster collar to stop the chewing which really does help but she still manages to get around it some how and have a good chew.

Thank you again for all of your replies it is much appreciated and I am going to try as many as possible until she starts to get better
