Enchante is 16 months old now. An affenpinscher female. She had knee surgery in early May for a luxating patella. And around about the time I started being able to give her more freedom to run around the house, she developed the most delightful new habit. I have two other dogs. One is a female affenpinscher who is almost 6 years old. Enchante will stand or lie in front of her. Barking at Gigi. Barking. Barking. Barking. Until finally Gigi will stand up and bark back and run at her. This delights Enchante immensely and she will run around and come back and bark all over again. When I let them out of the crates in the morning, but I still am trying to catch some more sleep . . . they play this delightful game. When I am working and on an important phone call, Yup. What fun to play that then. Or at night. Why oh why, has she started doing this? And how do I persuade her that this is NOT a fun game at all? The 2nd doggie I have is a little over 2 years old. And her and Enchante like to run around playing. Nice quiet non-barking playing. But with Gigi, maybe because Gigi doesn't run around and play, Enchante just insists on barking at her. Gigi doesn't seem upset by it. She either ignores it. Or finally gets enticed into the game. First grrrr-ing. Then running and barking back at her. And her tail will start wagging. And sometimes she will do the puppy play bow. Now me, I am very very irritated by it. Probably because Gigi has a cute little bark, but Enchante has a big dog bark in a small dog body. So loud and deep . . .
