It took months for our rescued dog to truly settle in. I thought he didn’t have a wag. Never wagged his tail. Little by little though we got a wag. Just one lil swish to start but as time went on he got more confident. Now sometimes he wags his tail as he dreams and I think that yeah, finally now he’s happy. You have to have a lot of patience, I can’t say it’s been easy, but I’m so glad we found him!
