I have a mini dachshund and I got her when she was 3 months and is my first dog. She is a little over 5 months now and I have not been able to get her house trained. I have been able to get to to use pee pads inside her play pen which she goes on them about 90% of the time. Sometimes she will go right next to them which is frustrating. I've been wanting to transition her outside but she refuses to go. She will just hold it in until we bring her back inside. Even going to to dog park, she will not go until we get back home. I have tried putting her on her leash and standing with her outside until she goes but nothing. When I cannot supervise her or when i'm not at home, she is inside her crate and most of the time she holds it when shes in there with an accident here and there. Any tips on how to get her to go outside?
