2. Australian Shepherd

Like the Border Collie, the Australian Shepherd is a high-energy herder that forms intense, unbreakable bonds with their handlers. Aussies want to be wherever you are, closely monitoring your movements. Unfortunately, this devotion makes them highly susceptible to separation anxiety.

When an Aussie is left alone, they often panic. You might come home to chewed doorframes or receive complaints from neighbors about non-stop vocalization. Teaching an Australian Shepherd to tolerate your absence requires gradual desensitization to your departure cues—like picking up your keys or putting on your shoes—without actually leaving the house until they learn to remain calm.
