I've been struggling with teaching Summit how to retrieve. I read the methods on Never Say Never Greyhounds and taught him to target a toy but after that I was stumped. He has about 8 toys all together. Every time I see a good sale or something not too expensive that is different I'll buy it hoping to find something that sparks his fancy. Nothing. I tried rubber toys with squeakers, plush toys with squeakers, stuffingless toys, frisbees, plush toys with those honking squeakers, nylabones... nothing. He wouldn't look at a toy never mind picking it up. He simply wouldn't put something in his mouth if it wasn't edible.
