    Just finished reading "Don’t Do Me Wrong: Rescue Groups and Dog Behavior Knowledge" and it speaks so much to what is going on in the rescue world now. Save them, get them out fast!.... it seems to be all about the numbers, but to what end if they are warehoused in cages or in foster homes who become hoarders or placed with people who are horrible matches. I have so much anxiety and sadness just watching the videos and photos some of these groups share it has made me limit my time on social media to avoid it. So many dogs, so misunderstood. It's a credit to how wonderfully resilient they are when you think of the buffoonery and downright dangerous situations they are sometimes put through to make "us" feel good.
