He is such a cutie! My last little girl was a black and tan smooth hair.
Please do not think of a crate as a cage. I have had dachshunds for over four decades, and, each and every one of them viewed his/her crate as a special safe place, kind of like having their own personal room. I usually left the door open when I was home and often one of them would grab a toy, or a chewy stick and go into the crate to either take a nap or chew on the stick. They would also retreat into the crate when my granddaughters came for a visit. I think they needed a break from all that play.
Did you know that if your dachshund has a bad back issue, the statistics say one in four will, that they will have to be crated 24/7 for 6 to 8 weeks to either recover from surgery or to heal without surgery. What if a hurricane or other natural disaster occurred in your area and you had to evacuate? Some emergency human shelters require that your dog be crated. We had to evacuate once when a regional power outage happened in freezing weather. All hotels with generators had no vacancies and we had to spend the first night in a shelter, although we left the next morning to stay with my friend who lived five hours away and was not affected by the power outage that lasted two weeks and affected half the state. In the event of an emergency, medical of natural disaster, it is less stressful on a dog that is comfortable in his/her crate, and less stressful on you. Also, if you crate your chewer when you are not home, he will not be able to destroy your home, or even worse, bite through an electric cord or get into something that might kill him. Start by making the crate a place he feels safe and wants to be in. A nice chew stick and blanket or some treats should make him want to enter. Leave the door open for a few weeks, and then gradually leave him crated with the door closed for short periods of time. Praise and a treat when he goes in, and more praise and treats when you open the door to let him out.
