I have three daughters. 17,16,12. They all want to be active with raising/training Ragnar, esp the 12 y/o.
Took them a couple of days but they finally understand----
1. There is absolutely NO WAY they can go near Ragnar and expect him not to nip/bite, just ain't gonna happen..... He is a 4 month old Doberman with a michevious kids mind that will scratch and draw blood with his playful chomping.
2. One must be prepared walking around the house when Ragnar is in "free roam" status.
3. Watch for the signs and motions of Ragnar coming at you with a dober-shark nip/bite.
4. When he does come and he will---be ready to redirect with a chew toy or stand tall and give him a full toned--NO!!!
After a solid week of watching them interact with Ragnar, they understand and know his posturing. When they see him setting it up, they quickly grab a toy and redirect. Funny to watch because I see it preemptively and start laughing because I know what is coming next--I tell them to be prepared with a chew toy or become the chew toy.
I really expect this behavior to disappear with obedience training and him growing into a mature Doberman.
Are you giving him enough stimulation and exercise?? I know that my work schedule sometimes does not allow this and boy, can I tell the difference with his demeanor and attitude. He becomes an unhappy, amped-up destructible little monster. Don't forget the saying---- A tired Doberman is a good Doberman.
