I'm still working on Odie's recall at 21 months old

He was no problem until he hit 6 months old and from then on, NOTHING will recall him from another dog, it's very hard work and I'm trying a variety of things to tempt him back.... I'm also trying to teach him 'stay', which we've never been able to do, which would help him not bogging off in the first place

There's lots of info on here for recall training including a sticky post.
