Two of my nephews whom I love so I won’t unfriend them. You can go to their wall and change it so that they don’t appear in your news feed. It doesn’t notify them and I protect my serenity. I’m about to do that with my sister in law because she posts up to ten dog related links per day. It’s a bit tedious.
I’m glad it isn’t only me. I’m only on Facebook mostly because of family and close friends but I have many friends and family that post mostly dog links. I have dogs and cats and love them all but it’s getting on my nerves.
