If I let the dog out of the leash outside, I can't get him back on the leash. He doesn't come to me and then he runs outside for an hour and doesn't want to come back. He runs after the other dogs. It's a dachshund.
Dachshund is no idiot. You rehearsed the summoning incorrectly. It is necessary to summon, reward, praise. If you do not practice this, the dog will not come at all, because he knows that summoning means inconvenience, tying and even tearing. Only when you master the summoning, then the practice of summoning, sponge cake in hand together with a guide. Summon, pin together with praise and sponge cake. Praise not to spare.
