Yes, and it's terrible, BUT John Wick spends the rest of the movie deliberately, gloriously, and violently avenging the dog, so it feels really pro-dog overall.
NOT SAFE! around like 22 minutes, it is visual, but really short, and you only see it from kind of above of the person, it is also audible, it may trigger some people
Early in the movie, John lets his dog go outside to relieve itself. The dog runs back to him afterward, and a small pile of dog poop is visible in the yard where the dog had been standing.
