Ahh connemmara, I really feel for your poor doggie, I hope you find the right solution for him this year. Have you heard of the conditioning treatments in the form of CD's that you can buy that you can play to gradually get your animal used to the sound of fireworks. A bit like any phobia treatment it exposes the animal to whatever it is that frightens them and then gradually they get used to the problem. I think I saw this on a tv programme last year as a possible solution to animals suffering at this time of year. Obviously it will be too late for this year but perhaps you could give it a try for next year?
Cheers Sue
