I have a 5 month old female westie. The vet told me to give her a bath at least once a month. Her hair is course so I fear that if I give her a bath every two weeks her skin will get dry. She is constantly scratching herself, that I noticed she is losing some of her fur. She doesn't have fleas. I check all the time. She's walked on a leash. If she had fleas, she would pass it to the other dogs. Somebody had told me that westies need to be pricked. Does this have anything to do with it and is it painful for them. The fact that she has two layers of coat, is that also a reason for her scratching. I'd like to find about this, before I take her to the vet. Please help.
