The devil dog comments really saddens me

We have a 6 month old chi and he's just so lovely and great addition to our family. Before we got him the best advice was to train him like he was a Rottweiler and it's paid off superbly. Still, I have people laughing at me when I've told them I'm taking him to puppy classes, teaching him recall etc. People seem to think it's ridiculous. I guess it goes to show why they have a poor reputation as training them isn't seen a necessity.
We never used potty pads, just took him out several times a day and soon enough you'll start to notice a pattern in their potty needs. There were accidents but as he's so small, they were easy to clean. He's six months on Saturday and looks like he's now turning a corner as we haven't had an accident for a while. He never had an accident at nighttime though and I only had to spend 3 nights in the beginning to take him out for a 3am pee, other than that he has slept through.
He's also not chewy or destructive at all. He's never been biting the kids or the adults either. He sometimes mouths a bit but it is very gentle. He's very playful but not hyper at all
. He also enjoys long naps in his crate, especially if he has his heat pad with him.
He absolutely loves meeting people and is everyone's best friend. He can be bit weary towards unknown dogs but not for long. His best buddies are a cockapoo and another lab puppy. I've gone out of my way to socialise him with other dogs, especially with big ones.
In the evenings, he sits on the sofa with us. In the beginning he had zoomies right after the dinner time but this is fairly standard behaviour for all the puppies. Now he flops on the sofa like the rest of us and doesn't move until the bed time
. He might alternate between our laps and his snuggle sack but he's very content on just chilling the evenings with us.
He's also such a funny personality, very clever and loves to learn new tricks. Being an easy portable size too is a huge bonus.
This turned out to be a bit of an essay but it is frustrating to read people slacking of this breed and even more so being frustrated at those who have a chi but won't bother training them at all.
