10 More Annoying Mistakes You Never Noticed In Friends

10. Chandler's Changing Fears

In Season 7 in "The One Where Chandler Doesn't Like Dogs" he fully freaks out because there is a dog in his apartment. He had even told Monica that he was extremely allergic, claiming that his throat will close up if he's close to a dog for even just five minutes. When Phoebe says that the dog has been there for days, he has to admit that he hates dogs. He's even terrified of puppies, looking around in fear when someones mentions them.

Yet, in Season 4 in "The One With Phoebe's Uterus" he walks into Monica's apartment while Phoebe has a pug there. He doesn't react to the dog besides making a little joke. There is no sense of the strong fear he reacted with in the later episode and no mention of his alleged allergy.
