There are a lot of videos that are going around wherein people have assumed that they have tried to save dogs, but they have gotten baby foxes instead. To prevent this from happening, you should know the differences between the two.
Dogs usually come in different breeds, so their appearance may not always look similar to the fox. Dogs are known to be domesticated, which means that they will be able to live with humans and their households. Foxes are not domesticated, which means that they can cause havoc when humans force foxes to live with them. Foxes usually have markings found on their ears that will let you know that you have a fox in your midst. Look for black-tipped ears to be sure.
