Hi there,
Generally it is best to do most of the research before the purchase , however I do realise that unfortunately a lot of the time it is the other way round.
I personally don't westies they are more prone to skin problems than any other breed.
If the puppy was bought from a genuine breed enthusiast that knows their lines and offers support them hopefully this is not something you will have to worry about.
Bad skin which is generally due to allergies, (whether genetic or environmental) can be controlled.
When it appears nobody can say exactly like any dog or human. Some are young and some are old.
Westie puppies start to scratch at a young age for a bit and I have heard people worry about this but what you tend to find is that it is the harsh coat coming through and if you rub the puppy you can feel it.
My puppy is nearly 10 weeks and he has been stripped out so all the little harsh hairs are now coming through quickly and it is tickling him.
