1) Don't join any forum that has been set up just to sell something.
2) Don't join any forum that charges to view the posts.
3) Check how many members there are.
4) Check how many new posts each day.
But most of all, check the main site, if it has many pages on the West Highland White Terrier (More than 1000) then the forum will be good also.
There are now many sites set up to sell you something, the people don't care if you have a problem with your Westie, they just want as many people to visit as possible.
You can always tell the bad sites, more ads than content, and always have something to sell you..
Keep away from them, join other Westie people at good forums
A good Westie forum will have many members posting each day, the date of the posts may go back many years. The forum loads up very fast indicating the popularity has moved the forum onto a dedicated server. Dedicated servers cost money, if your not charged to join the forum and use it (other than voluntary donations) it’s a good forum.
Good Westie sites will have thousands of pages on health, grooming, training, feeding, history. They will have guest books, greeting card systems, vet databases, dog friendly databases, and will all be for free.
The main site wont be set up just to promote a book, or some other product. These people read up from other sites, copy the content and pass it off as their own.
Do a who is look up, look when the site was first registered, anything less than 8 years is not worth bothering with.
