A close friend of mine has a 13 month old female great dane. My friend is having some troubles with her though. When the dog is inside she's usually pretty well behaved, but apparently when she's outside she just goes absolutely insane and jumps up and bites, totally knocking anyone who tries to be around her over!
My friend says that she tries to discipline the dog but the dog is too big and powerful for her to control without getting knocked over and hurt (i mean... over 50kg of dog knocking you to the ground must hurt a lot!). She really doesn't know what to do, has anyone got any advice i could pass on to her? it would be greatly appreciated!!!
