Hypoallergenic wet dog food suggestions and help with licky dog

[druid]

Maz has environmental triggers (all mites, sheep's wool, dander etc ) as well as food, her stomach can be affected as can her skin and ears.
The food allergy/intolerance testing indicated that nothing apart from eggs was a good fit for her. The elimination diet can be so long winded for dogs like her with multiple allergies.
She still has a 2 or 3 times each year that her skin goes black and she moults heavily, the scratching her ears till she yelps never happens and she only poops like a hose if she has got hold of a dead sheep or salmon.
I understand the testing is not 100% but for maz it saved years of trial and error feeding (can you imagine how long it would have taken to find out the only thing she could eat was eggs?) Also the money saved in medication, treatments and different food, all the time she would have been suffering.

If she has environmental triggers also a feeding trial wouldn't have resolved her issues fully anyway? Unless her environmental allergies are seasonal? So I would generally opt to medicate those dogs or try immunotherapy - no long winded feeding trials in that case as they can revert to a normal diet when medicated although we do recommend a "sensitive" option and avoiding the main triggers of chicken, beef and wheat.
