Why did Tella learn to bark?

Most of the time you hear about dogs barking it’s a bad thing :) For service dogs like Tella, barking can be a valuable tool to get help. Dogs like Tella help people with special needs live more independent lives. If someone with a disability was home alone and he or she happened to fall down and need help, they could have their service dog bark until a neighbor came to help.

Tella may be a petite dog, but she has a loud bark on her!
