Oh dear, theres so many things!
Megan, not too much really, if i had to maybe stop her pulling on the lead, grumbling at dogs when on the lead and barking like a loon at flyball but i can live with those things really!
Ellie, stop her growling at barking at people especially children. I wouldn't mind her stopping grumbling at dogs at training classes either!
Murphy well where do i begin?! Most importantly i would stop him having a go at dogs we meet out on walks, and stop him ignoring me when i call him. I'd like him to stop chasing cats and small furries too, but i think thats too much to ask!
Oh well, they do still have other attributes i love about them!
