So my mini dachshund, Bentley has been with me for a couple months now. When I first got Bentley he was a little overweight as most dachshunds are. I took him to the vet when I first got him for the initial checkup. I took Bentley back a couple days ago for a routine visit and he was noticeably lighter In weight than last time ( he's about 12 lbs now). The doctor may have been a little concerned because he asked me about what and how often I feed Bentley. And then we started talking about walking and exercise. I am very active person. I walk Bentley for about 10 minutes before work and then we go for out super long walks after work, which is about 3 miles there and back. Bentley has a ton of energy. If I pick up his leash for any reason he thinks we're about to go out and will go crazy, even if we've just got back from our long walk. I also live near a lot of shopping areas so we always walk to the pet stores and restaurants around my neighborhood. The doctor told me that I may be exercising him a little too much. Do you guys think I'm putting too much stress in his little legs?
