My dog wore this to our neighborhood Halloween walk and people were stopping us every block. The mask looks so realistic and he just trotted around like it was totally normal.
I put it on him and the entire room lost it. He just stood there looking confused while everyone took pictures.
I was trying to find something different for our dog this year and this was way funnier than another basic costume.
This is one of those things that somehow looks even funnier once it's actually on the dog.
We brought him outside in it and our neighbors immediately started laughing and asking about it.
He made fun of me for ordering it and then spent the next 20 minutes taking videos of the dog.
Our dog is usually impossible to impress people with because he's seen everything. This got everybody.
We bought the frilled one and the water feature makes the whole thing even more ridiculous.
We've done lions, sharks, and little sweaters. The dinosaur mask got the biggest reaction by far.
Oversized dinosaur features create an immediate visual payoff.
The costume is designed around the kind of reveal people instantly want to film.
Nobody casually ignores a dog walking around dressed like a dinosaur.
The mask can become the centerpiece of the entire costume without needing a complicated full-body outfit.
Most dog masks are flat and forgettable. ROAR is not.
