I think Wallace has "rage syndrome"

[IRescue452]

I was hoping a trial would maybe help my mom to see the little changes that make him more of a normal dog and maybe she'd see the need to continue forth with some sort of plan for him. Maybe I'm just seeing too much of myself in the dog though. Even when he's waggin his tail and chasing a ball around and everybody else would see a happy carefree dog, I see an unhappy dog who is just occupying some time at the moment. I spend the most time with him though and I feel like I almost know him inside and out, except for this one tip of the iceberg. I guess though, she's never going to go for even trying something if she sees nothing wrong. Its not going to hurt him if he stays the way he is now and never does get more aggressive, but its certainly no quality of life in my eyes if nobody tries. He eats, he sleeps, he plays, he goes for walks, he gets into the garbage -just like any other dog, but at the end of the day he still looks like he's ready to walk off into a mist and never return.

I think he's bringing me down, I was at a high point lately. Depressed people should not have depressed dogs.

If you're really uncertain about this, again, contact a behaviorist.

Understanding and training come before medication. And, I hate to say it, but maybe you are seeing him too much through your own personal, emotional bias. Maybe you can set up a relationship with a behaviorist and have them observe your dog over a period of time. If a second pair of eyes also sees something wrong with Wallace, then, by all means start behavioral mod. and drugs. If the behaviorist sees little wrong, then just try not to let your emotions color your judgment too much

Also, to narrow down Wallace's triggers, I highly suggest looking at this pictorial:

This clearly demonstrates that dog body language is MUCH more than ears, teeth, and tail. Once you understand dog body language well, you can start applying it to Wallace and that will help you in determining at what point he starts to aggress. Then, write it in a journal and try to find some pattern (sometimes they're really esoteric, but they're there!).

Has he ever had this thyroid checked? Thyroid problems can cause really weird behavioral issues at times, and when you mentioned he seems to sleep too much and display some depressive behaviors, I started wondering about it. If it hasn't been checked before, it may definitely be something worth ruling out.
