Q, as a pup did he have to fight for his food from the other pups,Along time ago I had one that did this,we worked it out that she was in a kennal with her sister till she was 6 month old ,her sister was the stronger of the two, so she use to hide her food from the stonger bitch,this is what we think started it off, sorry to say, could take her out lamping,at the begining of the night she was fine but when she started to get tired , that was when she started to hide the rabbits,some night she was ok, other she would piss me off
