I have a big sunroom to play this in but it would work in a yard as well if your treats are visable in grass.
Have the dog sit Back up about 5 ft and call the dog to come while having a small enticing treat in hand. As the dog gets to you put the treat under his nose and turn quickly while tossing the treat the opposite way it is comeing from. As soon as he gets that treat call come and turn and toss again so the dog gets conditioned to run at you when you call come.
I would use an apple cut up small and play this for 5 minutes at a time as well having kids play. Eventually I was throwing the treat up to 10 ft away.
Duke loved this game and it was great at wearing him out before bed time.
Well then I would not say the word COME unless you can make the dog come. The more times you say it and the dog doesn't listen the training is set for it to learn to ignore you. We also worked Duke outside with a 25 foot leed on so we could lure him in then treat.
When Duke was about 10 months old we bought an ecoller petsafe brand. I havd 3 acres and don't want any fences. duke knew how to come but sometimes deer poop or something was more interesting. I would give him a beep. Still nothing then he would get a zap. It is nothing worse then getting a shock from car door but it taps him on the shoulder and says HEY listen to momma.
We still use it the odd time for tune ups and just bought one for our little mutt Maggie. Do not use it for any command the dog does NOT know but if he knows come then they sure work great.
people always hated the thought till they saw how good Duke was My sister husband refused and say they were cruel till their dog was just a monster he finally gave in and said in 1 day they could enjoy her. Husbands uncle got a lab. After explaining to him about ours he went and bought one to try. He know loves them as well
I always pretend i have a treat in my hand. I noticed my dogs responded to me when I make a fist, I guess cause it looks like I have something good in my hand. Sometimes I have a treat and sometimes i dont so they never know when. Mine come all the time now, I just stand 5-6ft in front of them and close my fist like a hand signal, and they think i got something and come over to me when i say the command.When I dont have a treat and they come I go crazy with the affection and petting, then they get all excited and run around...lol.
