I have a 6 month old dobermann and have been having problems with her. Everytime i bring her to the park she barks, growls and lunges at other people especially small children and is worse to other dogs.
There was once i couldn't control her and she jumped on another much larger dog. She even manage to escape from her leash once and jumped on a small boy. I think she's just really excited rather than aggressive as she cried and whine when i pulled her away from jumping on that dog and she was just sniffing the small boy, but people who don't know her will think otherwise. I read that some behaviour problems stem from lack of exercise and excess energy , but i can't even take her out a walk safety.
Even when there is no one around the park it's difficult to walk her cause she's always pulling on the leash. I've even sent her for a one month obedience training but it seems she only takes commands with the choke chain on and indoors.
I can totally relate! Koda is 2 years old now and he continues to improve everyday with the methods I have adopted. It takes time but be patient. You want to control your dog, you have to think dog. Simply put-animal first, then species then breed and only after that, personality and you have to learn to communicate at each of these levels. If you'd like to know more, I would be happy to share. And if I can just say, before socialising with other animals, giving her tranquillisers, it's YOU that needs the training not her, just like it was for me.
Remember! Large breed, high energy prey driven natural born athlete and dominant breed. What does that tell you? The dog breeds from which the Doberman Pinscher was derived included: the Rottweiler; German Pinscher; Greyhound; and the Manchester Terrier...uh...all very dominant breeds. I stand corrected. So if YOU are not her leader, she will be yours. Bear that in mind. So once again you need to think dog and carefully consider the breed and what they were bread for. She's no Duchshund who I might add can also be very stubborn and dominant but a subtle difference between the two I would say. So if you are not in charge, she is. It's as simple as that and she's walking all over you as Koda was doing to me until my mind was opened to a different way of thinking. It's important that you think correctly, because I swear to you, I sometime think that Koda can read my mind! Energy!
Master the walk! Who is in charge? You or her? In a pack. Does the leader of the pack lead from behind. Establish a pack order in your home-important. It can still be relaxed and lovey-dovey at home, but certain behaviour is unacceptable and should not be tolerated and you need to deal with it positively particularly if she is allowed indoors.
"Dogs descended from wolves, and deep within the psyche of your dog lies instincts it has retained from its wild ancestors. In order to live with and communicate with your dog you need to understand why you must maintain alpha position in the "pack." "http://www.dogbreedinfo.com/topdog.htm
Many here will disagree with this philosophy of dog handling, but it just makes perfect sense. I am not going to recommend who I think you should 'google', the last time I named the person who has helped me tremendously ONLINE and with his dvd's I was shot down!
Exercise important- develop a daily routine of exercise. I'm afraid, I don't think walks are enough. They need to run. Get a 20m rope and take her to an open beach or field and play fetch. Swim her! Koda loves swimming and fetching his favourite toy. Dont let her legs touch the ground for an hour at a time, if you have the time. But she needs to walk well on the leash first. Develop a daily routine that includes A STRUCTURED WALK! It's not ho far you walk, it's how well she walks, where she walks and how she obeys your commands, otherwise you don't move and you put her into the position you want her in before continuing. Until she walks beside you, on the left where you want her, she does not walk in front and take you for the walk. She must ignore other dogs. When you are going on the "structured walk" (in the garden -anywhere) no distractions. Casual stroll late in evening a great time, different story. If you want some advice on this, feel free to ask. Koda is now so disciplined when we walk together. There's no quick fix, but she'll learn quickly. Dogs need to be directed every step of the way when they are with you until they learn. My commands when we walk are, BACK, HEEL AND FREE...to walk ahead with MY permission. You really don't need to go for training, but yes, YOU need training on how to speak dog. The information is out there on the net freely available for you. And all that other "socialisation" business- it stands to reason. Think about any animal or human being, but you need to understand and speak dog.
I wish you all the best and please feel free to message me privately if you wish. I hope this helps! Peace.
