Dallas Zoo mourns the loss of beloved red river hog, Hank

With heavy hearts, we announce that 15-year-old red river hog Hank passed away due to T-cell lymphoma. Hank was loved by our animal care staff and guests alike, and will be greatly missed.

Hank was loved by many, and will be missed.

In January of 2017, routine bloodwork showed that Hank’s white blood cell count was extremely elevated. After further testing, he was diagnosed with T-cell lymphoma – a type of cancer that begins in immune system cells and affects the lymph nodes. Hank was moved to a special area behind the scenes where he could be more comfortable during his oral chemotherapy treatment.

Chemotherapy can cause some negative side effects, but Hank thankfully displayed none and continued to be a happy and active hog during his nearly two years of treatment. He even enjoyed going out into the exhibit with his friend, Zena, at least once a week for a few hours, before returning to his enclosure behind the scenes for an afternoon nap.

Our dedicated animal care staff worked very closely with Hank during his illness. In addition to his treatment, keepers saw to it that he had plenty of enrichment and training activities to encourage his natural behaviors and keep him mentally stimulated. Mulberry logs were his favorite. Keepers say that he would spend hours chewing all of the bark off of them. Animal care staff members spend a lot of their day behind the scenes, so Hank received lots of love and attention. He particularly enjoyed getting belly scratches, which keepers were always happy to give.

Prior to Hank’s treatment, there was very little information available about using chemotherapy to treat hogs with lymphoma. Our veterinary staff were unsure what to expect, but because they chose to proceed with Hank’s treatment, we were able to give him nearly two more years of happy and enriched life following his diagnosis. Veterinary staff gathered significant information during Hank’s treatment that could potentially help other animals in the future, here at the Dallas Zoo and elsewhere.

Since Hank was with us for 8 years (he came to us from San Diego Zoo), many of our keepers got to care for and love him. Here are some of their fondest memories:

“I worked with Hank at my last zoo. Every time he heard a tractor come by, he would run and vocalize with excitement. And, when approached would immediately lay down for scratches. He greeted me with that same excitement, every single time!“ – Tanya B.

“If you just lightly touched his belly while he was standing, Hank would tip over like a tree falling and lay there waiting for belly rubs. I also loved to push his pine shavings into a giant pile and watch him bury himself completely in them when he went to bed. “– Jessi V.

“Hank used to run laps around his habitat. When he finally completed the behavior you’d see him sprint around the corner to the ‘finish line’ with his ear tassels just flying in the wind. In that moment, he seemed like the happiest hog on earth.” –Christina E.

Dallas Zoo animal staff remain committed to our animals throughout their golden years

We love all of our animals at the Dallas Zoo, but our geriatric animals are some of the most special. When some of our animals reach retirement age and are no longer comfortable shifting in and out of their habitats, we move them to an area behind the scenes designed for their comfort, where dedicated keepers care for their every need.

Dara, the yellow-backed duiker

For Dara, the yellow-backed duiker, that time came about six years ago. Dara was one of our oldest and most beloved residents, and sadly, she passed away recently from age-related health issues. At age 26, she lived to be the oldest duiker in the Association of Zoos and Aquariums, and she had a wonderful and gentle personality.

Duikers are a type of African antelope. Their name means “diver” in Afrikaans, because they dive into vegetation and brush when spooked. Native to Central and Western Africa, adult duikers have a bold yellow stripe down their back, which becomes more visible when they’re on alert and their hair stands up.

Duikers are very intelligent – their brains are proportionally larger than other hoofstock, such as some antelope and gazelles. Most are hesitant of new things before they learn more about them, but Dara was very curious and loved to explore her surroundings. She absolutely loved pumpkins! She would roll them up and down the length of her habitat before finally eating them.

Although it was tough to say goodbye, we are proud to have provided Dara with the best possible care during her golden years. Her keepers made sure she had mats covering the floor of her stall so that she had better traction and a softer surface for her joints. Her keepers also performed routine hoof care, gave her hoof and joint supplements, and of course, lots of love and attention. Zoo staff say that it was such a privilege to care for Dara. She will be missed!

Honeydew, the tapir, enjoyed a special “cake” for her 35th birthday (January 2016)

Our other senior resident is 37-year-old Honeydew, a South American tapir. She is currently living out her “retirement” away from public view, where she is pampered with brushes, baths, special foot care, and leisurely swims in her personal pool. Honeydew’s sweet demeanor makes her a joy to care for and a keeper-favorite!

‘Rockstar’ cooperative cat aides Zoo medical study

Pull, poke and squeeze a cat’s tail, and you may not like the results – but Lakai, the Dallas Zoo’s 7-year-old mountain lion, isn’t like most cats.

He doesn’t mind having his tail prodded and squeezed, and it’s helping zookeepers and veterinarians explore a lesser-known medical field.

Zoo staff are taking blood pressure readings on Lakai’s tail using an inflating cuff, similar to one used on humans. The readings will help monitor his well-being and track data in a medical area without a lot history.

“There is very little data on blood pressure on awake mountain lions. The majority of blood pressures are taken on mountain lions while anesthetized,” said Dianna Lydick, manager of the zoo’s A.H. Meadows Animal Care Facility.

Lakai’s blood pressure training and readings are generating interest and buzz internally and throughout the zoo community nationwide.

“There are definitely people wanting this information,” said keeper Libby Hayes, adding that any time you can avoid aestheticizing an animal for medical treatments, it’s better for the animal.

To get to this point, Hayes and keeper Caron Oliver worked on tail training with Lakai every week starting in May. Over time, the mountain lion became comfortable staying in position, allowing keepers to grab his tail, prod it with a needle for blood draws and squeeze it tightly to take the blood pressure readings.

All aspects of the tail training is voluntary and done with positive reinforcement. If Lakai doesn’t want to participate, he doesn’t have to. Luckily, he doesn’t mind trying new things, Oliver said.

Nine things you probably didn’t know vet techs do

_mg_9548-deb-chase

It’s National Vet Tech Week and we’re revealing the surprising, sometimes gross, and always super-impressive job requirements that make vet techs so special and versatile. Our $3.75 million A.H. Meadows Animal Health Care Facility consists of five licensed techs, three full-time veterinarians, hospital keepers, and records administration.

Our vet techs work with some of the most majestic animals on earth, helping monitor animals under anesthesia; collecting blood samples; placing IV catheters and performing endotracheal intubation; filling hundreds of prescriptions; laboratory work; and assisting during procedures. The list seriously doesn’t stop.

Here are nine things you probably didn’t know our incredibly hardworking, smart technicians do with a healthy dose of good humor.

1. They geek out over abscesses. The process of lancing an abscess, flushing it, and then watching it heal is truly their idea of a good time.

2. They’re not “clock watchers.” They come in the middle of the night when needed; work through lunch during surgeries; stay late when new animals arrive, and more. (Vet techs may be superheroes.)

3. Techs are skillful phlebotomists. They draw blood from the smallest of birds and reptiles to the largest of mammals. They must know where the best collection site is: jugular for birds; tail vein for most snakes and lizards; subcarapacial sinus in turtles/tortoises; and the tail, leg, or jugular vein in most mammals. (Serious mic drop.)

4. They’re brave. Techs conquer their fears to help animals they’re afraid of, and they do it with a lot compassion.

5. They’re the only people EVER who look forward to teeth cleanings. During dental prophylaxis, they become giddy after snagging a huge piece of calculus (tarter) off an animal’s tooth. (No joke.)

6. They work with zookeepers to make health checks easier on the animals. Through voluntary training, animals don’t have to go under sedation; instead they’re taught to present body parts for things like, blood draws, vaccinations, blood pressure and more. Pretty awesome, huh?

7. Techs do it all and more. They’re the setup crew, the cleanup crew, the nurse anesthetist, and everything in between.

_mg_7137-dianna-lydick

8. They LOVE neonates. (Even capitalizing ‘love’ still makes it an understatement.)

9. They win “Best Supporting Actor” every time. “Techs are the wind beneath the wings of the veterinarians. Without techs, vets would not be able to soar as high as they do.” ~ Dianna Lydick, hospital manager, BS, RVT, VTS (zoo)

_mg_2036

Not only are our vet techs licensed professionals who have to pass a national and state exam, but all of our techs have a Bachelor’s degree, and an Associates of Applied Science in Veterinary Technology. They also are required to attend continuing education annually just like other health professions. Plus, they’re part of the Association of Zoo Veterinary Technicians.

To vet technicians everywhere, we honor you this week and applaud your work ethic, especially our zoological technicians: Deborah Chase, Cassandra Reid, Laurel Walosin, Eileen Heywood, and relief tech/hospital manager, Dianna Lydick.
