I was tossing this one around because the question is, when is too many dog photos too many dog photos, right? I don't think we're there yet. My instagram is filled with mega fit individuals that I scroll past really fast (it's a bit like the five second rule. If I don't see too much of them then they can't guit me and it's fine) and a sizeable portion of other people's dogs. I like those posts, because I like to see what these dogs are up to.
(They aren't as cute as mine, though.)
