I guess this is an agression/obsession question. Our Staffordshire Terrier is a very sweet and calm dog except anytime we try to play "fetch" with her. She won't give up on anything we throw until it's torn to shreds, she's demolished tennis balls, sticks, ball throwers, soccer balls, etc. She becomes obsessed and anytime another dog comes near her when she is "in the zone" (before she gets anything in her mouth) she lunges at their neck. She also overworks herself and gets bloodshot eyes. We've tried training her to "leave it" and "drop it" but she has no interest in obeying. Living in the city, we want to be able to leave her off leash so she can run around, but we want her to come back with the ball and not bite other dogs! Help! Techniques we have already tried:
1. Leave it, drop it...we can't get her to even accidentally drop it
2. Pressing on the soft spot of her mouth to get the object out. It doesn't work (I've raised other large dogs so I know I'm pressing int he correct area)
3. Offering a treat to get her to drop it. She has no interest
4. Offering ANOTHER ball, stick, whatever. doesn't work
5. Walking away from her and ignoring her. Doesn't work, she just comes to me with it in her mouth.
