What to do for a dog that thrives on....

She wants to play with the cat and the bunny. But she can't. The cat just sits there or runs off. She soo badly wants to play. She even barks at them.

The only way I've figured out how to play with her is to pretend I am a puppy and run my head into her, or jump on my 4s towards her.

She won't run after the ball or anything. What else can I do?

she doesn't seem interested in any training at all. I am just happy she's housebroken. She seems to really love me too. Such a mommies girl.

Keep working on the training, and on agility-like tasks. She'll catch on. That, and a good obedience class where she can interact with other dogs and maybe set up play dates!
