Good morning everyone and happy to find this forum. Reggy is our rescued Dachshund we got from the pound about 6 years ago. Due to the severe back injury he came with, we developed a special sack for him that he can burrow into without straining his back. www.dachshunddens.com is our website if anyone is interested in viewing our sacks, we also have an Etsy link to see more Dachshund Dens. He loves his and he models the Dachshund Dens we sell and we donate part of our proceeds to help homeless pets here localy and throughout the US. We love contributing to helping pets find homes and spay and neuter programs.
