Itching Dog

Our dog have been itching like crazy. She's been to the vet a few times for her itching. They gave her medication to help stop the itching twice and it worked but when she stopped the medication, the itching startd again. She's going to have an alergy test done in a couple weeks to see what she's alergic to.
   
I think it might be her food. She was on natrual balance but I wanted her on a senior (she's about 11 years old) dog food. The vet's office told me to put her on science diet. After reading so much about this food, I took her off science diet and started feeding her blue buffalo.
   
The vet's office said they don't think she has a food allegy. They think it's environmental and that switching her food before finding out what she's alergic to is a bad idea.
   
Why should I wait 2 weeks to try to help my dog from itching so much? I don't think changing her food is a big deal.
   
It's only been 3 days since I changed her food. If it is her food that is making her itch, how long before she should stop itching?
   
If it was environmental, I would think it would be seasonal and not year round.
   
Any suggestions?
   
Thank you,

If you think your vet is wrong, seek the opinion of another vet.
   
If the second vet agrees with the first vet, then either do what you are told or ignore them both but you do so with the knowledge that this is contrary to the concensus medical opinion.
   
If they disagree, then follow whatever advice you prefer but with the knowledge that you do not really have a concensus opinion.
   
While itching is annoying it is not fatal so while you think it is not a big deal to change foods, it is conversely also not a big deal to wait it out.
