I know I am in the minority, but I like Charley Chase, both is his own films, and as a director. I like everything everyone mentioned here - - especially the flea-killing clothes iron on the anvil, the perfume that earns Larry a slap, and the Chinese Yiddish - - but I agree with Tony that the spanking is bizarre and somewhat disturbing. Someone asked if that part of the short was cut when these were on television. I can't say for sure, but where I saw this short decades ago, that part was definitely in. I thought it was a strange ending then, too.
Just by the way, I always thought Bess Flowers was a little mature for this role`. At age forty, she could have had a child that age, but it isn't as likely as it would have been for a much younger woman.
Also, I feel nauseated watching Vernon mix that bicarb for Larry. It looks like he uses about a half-cup of the baking soda when only a teaspoon is appropriate. I just feel sick when I see Larry down that stuff even while I know it isn't real.
I know this is a minute point, but I include it in case anyone else is interested in minute points. The perfume Moe puts on the dog uses a glass rod attached to the stopper. It does look like an eyedropper, but I've seen these perfume bottles at antique/junk shops (when accompanying a friend who was antique/junk crazy and just had to stop at every such place in existence).
Also, I can't help noticing the resemblance of the dog washing set-up to sets and props used in Our Gang comedies. I speculate that such things became popular thanks to Rube Goldberg's inventions. RB's inventions were interesting, but - - in my opinion - - his books of Foolish Questions were far more entertaining. You can see how Foolish Questions inspired "Mad" magazine's "Snappy Answers To Stupid Questions" series, too.
Sorry to digress!
