on shorter distance my puppy answers on my call to come. longer distance, he just cant see me ?? and cant locate my place?? maybe both!? distance is about 15 meters. now 10 weeks old. is it normal ??? please help !!
For now then, for his own safety please keep him on a long line.
What about training him to respond to a whistle? The sound of a whistle is very clear and assuming he doesn't have a hearing problem, he should be able to hear it. Obviously if you think he does have a hearing problem, the vet is the best person to advise.
If you need advice on training the whistle, please ask.
