Lab, 2 years old, female, spayed

Question
My black lab has the following issues:  Frequent problems with skunk gland, ear yeast infections, constantly biting and and scratching her feet and now very dry skin and hair loss.  I need help!

Answer
Some would suggest a different chow.  Have you talked to the vet about it?  Usually it is best to work with the vet. If it is allergies, it may not be food.  

If you do try changing food, look for one with a different base.  If you are feeding a chicken and rice one, don't replace it with a more expensive chicken and rice one.  Go with lamb or beef of something else.
