Hey my cocker spaniel Ollie is 3 years old and we have always had a cat. The cat however is very nervous and runs away when Ollie makes a noise, such as whining or barking and then Ollie chases the cat if there isn't a door between him and the cat. Basically, Ollie thinks that whining and barking makes the cat run, so then starts a great chase game. However, Ollie is not aggressive towards her, he just thinks its fun. He has met her before, and touched her and never opened his mouth or touched her with his teeth. I'm wondering whether to try using a clicker to create a new behaviour is ignoring the cat. However I'll need some help with this. 1. Should I click and treat when he looks at the cat and is quiet, or when he's looking at me? 2. If he whines, should i walk away from the cat into another room until he quietens? 3. Should I start with a door between him and cat, and then progress to them being in the same room (Ollie on lead)? Should the cat be in a carrier or loose? 4. How can I progress to him ignoring the cat walking through the same room when he's lying on the floor or sofa off lead and with no treats or clicker nearby? 5. When the cat comes through the front door, Ollie barks and runs around the ground floor of the house. How do I stop him doing that? There will only be one person around, so Ollie will be on his own when the cat walks through the door.
