Covered in fur, scooping up poo and never happier. Working as a pet taxi driver provides plenty of challenges but plenty of cute, adorable clients to cuddle too.

Most regular taxis refuse to transport animals, so pet taxi services help fill the void; they move animals wherever their owners need them to go, for a fee.

Catherine Case has been working as a pet taxi driver since April last year but has always been an animal lover.

"I grew up with pets all my life as a child," she said.

"You name it, we had it."

Ms Case's job changes from day to day depending on what clients she has and what their needs are.

This week she started out by picking up Aaron, a service dog, to take him to his job at an aged care home.

"He's a very good helper ... he's very well loved," she said.

After dropping Aaron off, Ms Case drove across town to meet some new clients — a pair of golden retrievers.

"I actually do this just to keep me out and active," she said.

"I've been at Perth, Garden Island, Ridgeway, all sorts of places.

"I've seen places I never even knew existed in Hobart."

Her new clients, Molly and Louie, had to be driven to the Montrose vet centre.

The older of the two dogs, Louie, had a hydrotherapy appointment while his owners were at work; Molly just needed a walk.

It was the first time Ms Case had met the dogs and Molly showed signs of being a rather anxious, nervous dog.

"It's a thing that a lot of people don't know how to deal with [anxious dogs]," Ms Case said.

"If you ever see a dog that's scared, the best thing is to not make eye contact, lick your lips and yawn.

"It's amazing how much the dog will calm down."

Dealing with stressed animals was an occupational hazard for pet taxi drivers, and knowing how to keep calm and reassure both the animal and their owners was an important skill, Ms Case said.

Reassuring animals is something that comes naturally to her and is something she has to do most days with her own pets when she comes home covered in the smells of other animals.

"I put a lot of attention on to them when I come home.

"But sometimes they do just look at me and walk away because they know I've been with other animals."

Ms Case said working as a pet taxi driver was rewarding but not for the weak of stomach; there is always plenty of fur, dirt, slobber, poo and occasional vomit to deal with.

But no amount of gross stuff would put Ms Case off.

"I really love it.

"I've met a lot of people, great people, wonderful dogs, cats and rabbits and I've even looked after sheep.

"And they're all animal lovers and that's what I like, to meet people like that."
