Within the last year Joey has shown some aggression issues - Growling when I reached for nylon chocker to correct him, which I don't use anymore, and growled when I reached for his collar to pull him off the bed after he got into garbage. With the help of this forum and some books, I've been following NILIF for 3 months now. Great improvement.
Previously, I expected way too much of him and took alot of the fun out of training.
Anyways, I'm afraid I no longer trust my dog. I used to have no second thought about taking a cookie from him. He's never growled at me for that, but I'm still wary.
We used to rough house and wrestle. Now, his play growls seem more aggressive or atleast that's how I'm taking it now. My husband, who rough houses with him alot more than I do, says he doesn't seem anymore aggressive to him, so maybe it's just that I'm more causious, and sadly, more fearful of him. I think sometimes that his facial communication or his stares are more aggressive than they used to be. For example, last night I rough housed with him for the first time in a long time. He jumped for his toy in my hand and the thought went through my head that he could snap and go for my neck. Further, while my husband gets on all fours and and play jumps at him they stare each other down and Joey then does speed demon circles around the house. I tried this with him and felt like Joey was staring me down very aggressively, although he did just what he does with my husband and did speed demon circles.
Either, I'm more causious of him or he's more aggressive. Sadly, I don't trust him as much as I used to. Some days I'm comfortable with him and other days I just get a bad vibe.
Could this be an age thing in terriers? Any thoughts/suggestions at all.
