Any tips for overcoming ball obsession/aggression?
For the past couple of months, Bosco has become OBSESSED with balls. Since he's been a puppy he's been obsessed with balls, but I feel like its gotten worse. For example, when going for walks and he sees a ball on someones lawn, he'll run towards it with full force, pulling my arm out of its socket in the process.
But the worst is when we take him to the dog park. He is extremely athletic and fast, and can outrun most of the labs and german shepherds at the park. So when someone comes with a ball, he'll outrun all of the dogs, grab the ball and hold on to it. WHen other dogs come near him, even to sniff or say hello, he growls at them and runs off. Most of the dogs back off, but on a few occasions, some dogs have reciprocated the aggression and I fear a fight will happen one day.
This has gotten extremely annoying and I feel like we can't take him to the dog park anymore. It sometimes takes us 30 minutes + to catch him and take the ball back. Any tips on how to overcome this? I feel like we've tried everything and he can't shake this bad behaviour.
