ok well let me tell you what can happen during bunny or squirrel watching - sometimes the basenji just HAS to get at it - they are very focused on their prey and purpose - different than Sharpei's.
This made me smile, Shar Pei have very strong prey drives, mine are obsessed with 'hunting'. Only one of mine can go off lead the other two would be off up the fields even if it meant running 5 miles to get there. Are Basenji's the same, if they see something are they are totally fixated on it, nothing else matters, totally selective hearing when it suits them?
I know someone else who had a hole dug through her carpet and into the wood subfloor because the dog had to get out of behind the door.
I had a rescue Fell Hound years ago that in the space of 4 hours, dug through the middle of the kitchen door, then dug a hole in the hall way carpet down to some gorgeous Victorian tiles I never new I had I almost thanked him for revealing the tiles! lol
