Clinic Pets

Samson Burk

Samson Burk

Samson is a busy bee here at Knoxville Veterinary Clinic. He may seem like just a big teddy bear, but he has some important jobs to do and is not yet retired like Goliath. After coming to live here at the clinic, it has been a tall order for Samson to earn room and board. 

His most well-known job is that of greeter. He loves attention, and we are sure that, if he could, he would talk your ear off all day. It is thought that Samson may have been Forrest Gump in a previous life. He has never been a hunter, much preferring to spend his days giving endless love. He loves to give comfort to those that are sad, donates blood for our in-house patients in need of special care, and is always ready with a hug and a smile. 

Some nights Samson can also be seen at our puppy socialiation classes. He spends a majority of that time looking down his nose and them, letting the puppies play with him, and making sure they know when they are getting too rambunctious. He is a very good teacher. 

Perhaps someday Samson will earn his retirement like good and faithful Goliath, but for now he is quite happy working for his daily treats. We have a sneaking suspicion he would give people attention anyway. 

Stony Burk

Stony Burk

Stony Burk was adopted from the Marion County Humance Society, and has been our office cat for three years. He was previously adopted and returned several times-he seemed to know he was meant for more than the life of a house cat. Like Samson, Stony still has to earn his keep though. 

Stony is most recognizable by his fashion choices. He is always sporting a handsome lion cut, with boots and tail to match. On haircut days he can be seen strutting his stuff, proud to show off how well groomed he is. Of course, his good grooming makes him quite the lady's man. 

Despite his inflated ego, Stony is a very compassionate kitty. He enjoys greeting all the employees as they arrive in the morning-that's when he gets in his morning stretches. During the day he can be found checking on all of the in-house cat patients. Stony likes to comfort and keep them company, especially kittens. If any of our in-house patients makes a fuss, he is right there to offer a comforting paw or nose rub. 

Between the companion duties, comforting, greeting, and keeping the boys in line, Stony requires many naps. His favorite spot is napping in his bed by the reception desk, but has been known to take refuse on office chairs, and the occasional warm keyboard. 

Goliath Burk
In Memory

Goliath Burk

This staff list has been published in memory of our wonderful Goliath. Goliath was the weimeraner that lived here at our clinic until his passing in November of 2016 at the age of 13. Goliath spent his glory days hunting with Dr. Burk, and lived at his home for many years. More recently, Goliath had retired due to arthritis and age, so he spent his days at the clinic. 

Goliath waas most well known for making a stink quite often during the day (and we mean this literally), and receptionists were often seen spraying air freshener all over their desk. Goliath preferred to spend most of his time napping under the desk by their feet, and was the unseen culprit in many 'whodunnit' cases. 

When not napping or munching on treats, Goliath liked to spend time wandering outside and sniffing to his hearts content, even when it was time to come back in. Goliath remains in our hearts, faithful, loving, and a very good boy.
