@kgary Welcome to mastodon. I'm relatively new myself, but I started finding interesting people by using the search. Searching for interesting hashtags also showed who are writing about interesting topics, so that was a good way to find more people to follow. Actually more than a few of those people are from other mastodon servers. Turns out, it doesn't matter because the different servers are not isolated.

Forgot to mention - for finding dogs, lots of posts, pics, use some hash tags. #dogs #dogsofmastodon #mastodogs are all out there for your enjoyment.
