My 7 week old Border Collie x Jack Russell pup has been with us for 4 days now and refuses to pay attention when called. You can say anything to it, its name anything and its like its deaf. But we know it isnt deaf because it can hear small sounds from other things. How long does a dog take to respond to its name being called or a least knowing its owner is saying something? My family's previous puppies (3 Silky Terriers and 1 German Shepherd x) took 1 or 2 days to respond to name and with the German x took 30 minutes to teach Sit, obviously we reinforced it. Any help would be appreciated.
