I have a Rotweiler and shes 2 years old she got this obsession with rocks, water and car tires.. when she sees a rock she's going crazy she push it around with her nose and if she cant pick it up with her mouth (because it's to big) she takes the grass and pull it out with frustration..

when we swim in the swiming pool and we jump in shes going crazy, not because she thinks were going to drown, she bites the splashing and throw her rocks in the water .. when we go out and drive away she bite's on the tires..

i guess every dog is like that but i truely want a solotion for this problems.. we are tired of yelling at her, we also tought of letting her get babies and maybe grow up but shes like a little baby.. anoying, if you got a solotion please respond ;D!

Is your dog properly exercised every day? Obsession problems are very common in dogs that do not have regular physical and mental stimulation. It becomes an outlet for for anxiety, frustration, or suppressed energy.

The Rottweiler is a breed that needs as much exercise as possible, you cannot over exercise these robust dogs. They thrive on daily walks, jogging, running in a dog park, forest, or by your bicycle, and retrieving a ball. So the first thing you should do is probably giving your dog more physical work.

Then, correct her obsessive behavior as soon as you notice first signs of it. It's very important to recognize the physical and energy signs of her falling into an obsessive state of mind as early as possible, and stop them at that stage before the behavior becomes too intensive. When it's too intensive, it's very difficult to do anything to redirect her attention. Does she know the "leave it" command? Try to exercise her well to drain her energy and then "accidentally" go past a rock, water or car tires. As soon as you notice the first signs of her attention being caught by it, command her to "leave it" and use leash correction if necessary. If she obeys your command, give her a reward. Practise this as often as possible and reward her every time she leaves an object voluntary or at your command. It can take time, but be patient, consistent and persistent.

Don't hesitate to look for professional help if there is no improvement after a week or two. Obsessive dogs do not feel happy, they are prisoners of their obsession. It's like they're on a drug. If you can help her get rid of this "addiction", it's one of the best things you can do for your dog.

Good luck! Please keep us posted.
