Our male always will come if you call him. With our girl she will only come or do anything for a treat, praise she seems to care little about. Treats are the world to her.
I tried that with treats/praise on walks, once she sniffed I did not have them, she lost total interest like a light switch turned off. Bring back the treats full attention. They know when you have them and don't instantly.
They have great noses. The first thing she checks if the treats are there. You better have something better, if you dont have a treat, they care little what you want or give. The world revolves around them.
Our male hates to have any attention at all shown to him on walks. It's not the time or place for it to him.
The female tolerates a good pat or hug on walks.
I'm certainly not blaiming the dogs for our training faliures, just being honest with my personal situation.
You can't really blame a dog. Maybe others, including myself, can learn from my mistakes & failures.
