We have had seven dogs over the years, so I have some sense for what is normal. From the moment he stepped into the house, Cato was different. He didn't wag his tail. There was nothing physically wrong with it. Sometimes his tail arched over his back, and other times it laid out flat in repose. But wag? The best he could muster was an uncoordinated slow undulation. Not only did this make it hard for me to read his emotional state, I think it confused the other dogs, who may have mistook his body language for a threat.
Crate-training was a disaster. Since there is usually a human around our house most of the time, we have housetrained our dogs simply by taking them outside frequently. This way, they get used to doing their business outside. We use the crate for sleeping at night until the dog is old enough to sleep quietly in one of the human bedrooms. But Cato barked and howled in the crate to no end. He wore us down. After the first night, he ended up sleeping in our bedroom.
As he got older, the barking only got louder. I should have known about this. Plotthounds were bred as big game dogs and to track bear and hog. They have a choppy bark that carries long distances so hunters can follow them through the woods of the southern Appalachians. With few bear around the house, Cato directed his energy at articles of clothing, pillows, furniture, and the window casings.
