What kind of allergy does the vet think she has? Most allergies are food related so I would try switching her to a different food. My choice for dogs with allergies is California Natural from the Natura pet company. Here is a link to their website. California Natural Website

Here is a clip from the site:

Formulated for pets with sensitivities, it is made with the fewest ingredients possible in order to eliminate all the potential allergens that may be causing the itching and scratching associated with food sensitivities. For a pet food to do that, and still be nutritionally complete, you know the ingredients have to be of the highest caliber. It's just a Pure and Simple way to make pet food.


The food itself is a bit more expensive than most foods but it is also a lot cheaper than spending $300 at the vets. I would try this instead of putting my friend to sleep for itching. This is a problem that can be fixed and drastic measures such as putting your friend to sleep are a bit extreme. It may take a good three weeks or so for improvement. In the mean time you can use topical solutions to stop the itching.
