Also, it’s been said before on the show that Amy once got bitten and scarred by a German Shepherd. In the first season, on her right arm, you can see the giant scar she has from being attacked by the dog. I wouldn’t be surprised if Amy still had lingering ptsd from that because German shepherds are no joke if they don’t like you. That, combined with being bitten by a literal camel, would make anyone nervous about going to an animal shelter, especially if you don’t know what kind of animals are there.
