Daisy is going through the puppy equivalent of the terrible twos too!
Sometimes she is nice as pie (in the evenings) but during the day she can get really manic, jumping up and biting, ignoring me when I tell her to leave things, scratching at the door so I let her out thinking she needs to pee then she just messes around in garden and picks up poo, chasing the cats
However today was better, she recalled well outside, sat and stayed when asked and dropped her ball MOST of the time. God knows what tomorrow will bring though!
