I thank you all for your kind words and thoughts,and all your suggestions were good ones,but unfortunately Annie had 37 listed allergens,it's not as simple as people think,if it were then believe me I would keep trying,her body was riddled with sores,lumps and yellow hotspots,,even her breathing became laboured due to allergy to diesel fuel from cars,the vet this morning told my husband he's never seen allergies so bad and that she may even become allergic to herself,I know many will not agree with the decision I made but I did not make it easily,I made it for Annie not myself,she was in torment and I could no longer watch her knowing she had no quality of life,seeing her at peace has made me only more sure that I made the right decision,when the vet injected her he said ,Annie you can play on all the grass now which set my husband and son crying,so as you can see its hard for all of us,she did not feel a thing just went sleep peacefully,and I feel happy for her now she's no longer itching and chewing at her body as hard as the last 14 months have been I feel I had a special friend in Annie ,we had a bond and it was my duty as her friend to help her,karen
