Meet Carl. Carl is a 2 year old rat terrier mix that has been with us for over a year now. Carl loves his people and consistency. He is also one of the highest jumpers we have ever seen (like, insanely high). However, Carl has stranger danger and some other triggers we haven't been able to put our finger on, which is why he has had a permanent residency with us for half of his life so far. Carl would do best in a low-key home environment without many visitors and a regular schedule. And while we love having Carl be an everyday part of our lives, it's his turn to find a forever home.
