[SIZE="1"]*That's a new thread about the same problems I have posted here: [url]http://www.kingdomofpets.com/dog/forum/dog-behavior-problems/1228-agression-issues.html[/url] - the vet had checked and said it is nothing to do with the surgery he had, so here I reopen the topic in a more arranged thread.[/SIZE]
Kosmo is a one year old Malinois mixed castrated male, who I adopted 7-8 months ago from a shelter. Kosmo was alright and fine, just had some puppy issues and nothing special. In the last two months, Kosmo was developing some aggression issues and some more problems.
He is being territorial about my yard - if anybody gets out and closes the door behind him, Kosmo barks and jumps on the door. It also happens when there are birds outside on the yard etc., it's like he doesn't allow anybody to step outside without him being there. But if he can go out, he doesn't show any signs of aggression or anything like that, only when he is not able to walk out too.
This was the first signs of aggression Kosmo was showing.
Later on, Kosmo started to be even more aggressive about my father, (there is a leash attached to his place, that's instead of a crate) if he is tied to his place and my father passes by or just doing some stuff, he usually barks and lunges at him. He also sometimes bark at other family members that passing by - but this is very randomly, he sometimes does and sometimes doesn't.
There's a new problem that Kosmo started to show lately - sometimes when I take him out for a walk, he suddenly without any reason starts to bite and pull the leash with his mouth, while also growling and jumping up at me. If I try to take control over him by holding his collar he will try to bite my hand and gets even more crazy. There was a time where he did this and he managed to get released out of the collar, and he started to run and sprint around. Luckily, he listened to my recall and I managed to get him back.
From now on I take a few treats and when he starts to show this behavior I tell him to leave it and he leaves the leash and I reward. If I have no treats, he'll do it.
I started to work on a better "leave it", "drop it", and "heel" commands, in order to be fully controllable on this kind of situations, but as I mentioned - no treats - no responds.
What looks weird for me is that Kosmo doesn't show any other signs of aggression like food bowl aggression or dominance about his toys. That's all about his aggression issues.
Besides that, Kosmo has some other issues like:
-He usually doesn't comply or listen to my commands if I do not hold any treat or something he wants.
-He sometimes asks for attention by nipping / biting or by stealing something and running away.
-He can sometimes just start to nip while someone or even me petting him, and it happens a lot.
-He attempts to steal food from the counter and table, and we can barely eat normally if he is not tied or resting, because he bothers everyone at the table.
I also want to mention that I assume alpha dog techniques but I'm not sure about him understanding he is the lower rank. He doesn't get food from the table while we eat. I usually train him and work on his command a few times a day. Why does he still behaving like that?
I hope it's all enough details and sharp, if you still got any question just ask.
Thanks,
