Ever since we got her she would have these times where she would shake, we even thought it may be shivering because she was so small, or maybe because of her new home and all. She still "shivers" now and then but what has me a bit concerned is that she hardly ever wags her tail. She'll do it when someone comes home or if she's tracking a scent in the yard, but nothing like other dogs I've had over the years. They would start wagging just at the mention of their name. She gets plenty of attention and someone is always home so she's very rarely left alone. I just wonder if we're doing something wrong or if there is something we could do to help encourage her happiness. We're even considering a second beagle for her to bond with.
