I'm looking after a friends dog this weekend. He's a large greyhound x, about 2 years old and they've had him 7 months. In the house, he's an angel; barely even know he's here. On the park, off lead, his recall is 100%, he greets dogs that come over to him with a wagging tail then walks away, never approaches dogs, barely even takes any notice of them and just wants to play ball or have a sniff in the grass.
On the lead however, he's a nightmare. He's better than he was when they first got him, as he will now actually accept a lead, but he's so strong and if he so much as sees a dog, he turns into a snarling, barking leaping around thing, even if it's a dog that two minutes earlier, he passed off lead with no problems.
I'm currently popping both dogs in the car and driving to the park, as I'm really struggling holding two when he kicks off as it triggers my dog off barking too, but obviously it's not ideal in this weather to be going in the car! His owners are at a bit of a loss as to what to do, but have mentioned they will be contacting a trainer as the behaviour is beyond their knowledge.
Anyone got any tips?
