| It truly is great that you love your dog so much, BUT you have to get contol over the dog and let him know that you -- and not he -- calls the shots. If you don't, your dog seems at great risk to bite/hurt someone. He is only going to get stronger and more willful unless you take strong action now. Loving your dog right now has to mean tough love.
Some searching on this forum should locate some excellent threads on reestablishing your dog as a dog and you as the pack leader. The gist of these is that food, affection, walks have to be earned by your dog. For example, make your dog sit before you pet him. If he jumps up, STOP petting and ignore him. Don't pet him because is thrusting his nose under your hand and demanding attention. Ignore him for awhile and then, on your terms, make him sit/lie while you tell him what a good boy he is. Also, make your dog work for dinner -- i.e. go thru basic obedience drills -- sit, lie, stay -- before your feed him. Make it clear that he must listen to you and please you before ANYTHING good will happen. Keeping your dog off the bed and furniture will also reenforce his lower status. At first, you dog will be dismayed and displeased -- he is used to being the boss. He may even growl and nip. You must be stronger and more stubborn that he.
Because this may be quite difficult, I strongly second those you have suggested a trainer. Also, going thru obedience classes will help your dog see you as someone who is in charge. Although he is cute and you are laughing (and I agree a sense of humor is indispensable with a Rott in the house), please take this seriously and do right by your dog. Just remember, if your dog hurts someone, he may have to be put down.
If you handle this right, you will ultimately have a wonderful, well-mannered companion.
Best of luck |
