Oliver is now 9 months old, we've had him since he was 10 weeks. From the beginning we trained him with dog food as treats to sit, lay down, stay, shake, etc, which he now does extremely well. We also started playing fetch. Oliver will go "get" anything and everything we throw. Bringing it back is a whole other story. He likes to make treasure troves of his fetched items. Related to this is his tendency towards thievery. He steals shoes, socks, any small items and relocates them. No chewing behavior going on, just hoarding our things. Most of the time, this is related to wanting our attention, as he is good at stealing from the one who's attention he wants.

Is there something intrinsic in Cavaliers that keeps them from bringing us the ball? If not, any tips on how to correct this behavior? Thanks!
