Lhasa Apsos

As anybody come across their lhasa apso licking nad scratting themselves excessivley. I was told it was a foos allergy I have tried food with no colouring or additves and that didn't work. I was told to try a low protein diet and that didn't work. Can anybody please help me and my dog. DESPERATE.

How long each day are your dogs left alone? I'm not saying this is NOT a food allergy, but it is possible that they are licking out of boredom. The scratching is more so the sign I would say applies to all types of allergies, (along with licking) It could be food, or it could be environmental. Do you bathe them with any particular shampoo, and how often do you bathe them? Is there a possibility that they came in contact with fleas? It would only take a bite of two to drive them crazy. What foods have you tried? Perhaps I, or someone else on the board can recommend a better choice. What food are you currently feeding the dogs?
