Well, dogs are supposed to be loyal and friendly, not abound in intelligence. So, I don't think he really had that much to complain about.
LOL!
A friend had a Pit Bull named "Daz".
Honestly, the level of stupidity that Daz was should have been fatal.
Daz would jump straight up and down in excitement whenever you looked at him.
The fatal stupidity part is that he'd do that no matter where he was at, under a table, in front of you under a heavy cast iron pan, under a chair -he was a 'self punishing' dog.
You could hold a brick in your hand out level with your chest and say, "Daz!" and he'd jump into it.
Repeatedly.
Not sure where Daz is now, he ran out the front door of my friend's place and saw LOTS of people outside and just had to go and lick everyone he saw.
They never did catch up to him, and no-one said they found him.
I wouldn't be surprised if Daz was still running around jumping in front of and licking everyone he saw.
