My toddler likes it but the show is objectively bad. It's yet another one of those "kids drive dangerous vehicles and do the adults' jobs" shows that you've seen million times before. In this case it's a bunch of dogs who run a construction company. They can magically build anything and never have to worry about finances, materials, logistics or basic laws of physics. Your disbelief better be suspended like never before. The plot of each episode is inane as are the "humor" (dog puns and stupid slapstick) and generic life lessons that get crammed into every kids' show these days.
The visuals are cheap and every character looks and moves like it's made of jello with all that bouncing and wobbling. At least the music is not completely terrible and there's a couple of good songs in there.
Bottom line: Pupstruction is a completely pointless show that brings nothing new to the table, is not smart or creative, rips off countless similar shows that came before it, and it really just doesn't need to exist.
