Hi Michelled, :-)
Could you tell all this from the pictures or did you see them? Runny eyes can be a number of things, could be just simply needing the hair trimmed at that eye. I always trim the hair back as early as 4-5 weeks just incase as the harsh hair can come in so quickly.
Not sure about the pink tail as it is generally hard to see any skin trouble unless you move the coat and look inside it. Very very rare to see any skin trouble on such a young puppy. Westies tails are never docked.
Coats are something you need to actually have a good look at I think. Some can appear more fluffy but have a perfectly good double coat. Some are just fluffy with a single coat which is very undesireable and couldn't be shown. Some have a nice tight double flat coat which is my preference but some breeders like the first option as yu can get furnishings on them at 6 months for the showring. You can also get nice tight coats but that are only single coated so the coat would need to be looked at. I am showing a puppy dog tomorrow who is just 6 months no furnishings but a beautiful tight harsh coat.
Being honest about coats, buyers are the worst for buying a westie because they think it is a cute fluffy things. My first litter I had one that was a bit fluffy and every single person wanted it because it appeared cuter LOL it was the I would never ever have kept.
Some ears don't got up till they are a good 4-5 months , I believe or certainly in my experience when picking puppies that if they are still down at 12 weeks once they have had a bit of hair trimmed off them then their ears may be on the big side. Again that is not a rule just my thoughts when I am picking puppies. At 8 weeks it is common for them to still be down.
Hope I have covered everything :-)))
