With another winter approaching, both herds of the Chincoteague wild ponies will be rounded up October 8 and 9, checked over one by one by Dr. Charlie Cameron of Eastern Shore Animal Hospital and his staff and given de-worming medicine.
This is one of three times a year when the ponies are herded into corrals from the ranges on Assateague Island where they live for a visit with their doc. The Chincoteague Volunteer Fire Company which owns the ponies pays the Chincoteague National Wildlife Refuge $1,500 a year for a grazing permit which must be renewed each November.
Dr. Cameron is not expecting any medical surprises. At the July roundup he was pleased to find no evidence of a calcium deficiency which had appeared over the past year, giving the herds a clean bill of health. Dr. Cameron of Eastern Shore Animal Hospital in Painter and his associates have been taking care of the ponies since the spring of 1990.
Over these past 20 years, the Chincoteague Wild Ponies’ lactating mares have been treated occasionally for hypocalcaemia, a calcium deficiency, which can be life-threatening to nursing mothers. Usually two or three mares will be deficient, said Dr. Cameron. Some years there are none. But about 10 mares suffered from this ailment last year.
“Last year was the worst year we had had in a long time,” said Dr. Cameron. “We had one other year that came up to about that level about 15 years ago when we had something very similar.”
“Last year, we were actually on boats for the swim when they called me from the fairgrounds with mares down. The day of the swim, we had a mare down in the pen that morning before they took them out of the holding pen. That’s not the first time, but we’re prepared for it. We give them at least 500 ml of calcium, dextrose, magnesium and a little phosphorus, sometimes, 1000 ml, dependent on how they respond.”
“This is really more common in dairy cows. Dairy cows are more prone to this. It’s not a real common phenomenon in horses, although it does occur commonly in this herd,” said Dr. Cameron. “I think it’s because there’s deficiencies in the soil. There may be hereditary factors, too,”
Years ago, the ponies began receiving intravenous calcium treatments in an emergency. Dr. Cameron explains, “You can save their life if it’s given in a timely fashion. We’ve been doing it for years.”
We know what to look for, said Dr. Cameron. “The firemen have been trained. So we usually get them before they actually fall,” said Dr. Cameron. “We’re ready for it.” “What happens when an animal becomes hypocalcaemic, whether a horse, a cow, or a person, is the muscles start firing out of control and they’ll literally fall over. The first signs we’ll see is their jaw muscles start twitching and they start breathing in very rapid thumps. Their diaphragm is firing out of control,” explains Dr. Cameron. He said, “Calcium is essential to proper muscle tone and control.”
“This year, we didn’t have the first case,” said Dr. Cameron. Mares that were tested in the spring were either slightly low or right on the borderline of calcium deficiency. “They’d had a rough winter. In the spring, they didn’t look good; but when that grass comes in lush, they put on weight.”
Dr. Cameron directed that the ponies’ diet be supplemented with calcium fortified hay and mineral blocks at the round-up. Test blocks were initially put out about a month before the round-up. “We supplemented them with alfalfa hay, which is high in calcium. We also had these mineral blocks that Southern States donated, which are high in calcium and magnesium,” said Dr. Cameron. “These two minerals are important in a mare’s diet as far as helping them make milk and keeping their blood calcium levels in a normal range. The overall condition of the herd was very good,” said Dr. Cameron. “A lot of them were fat.”
“The jury’s still out. I think what we have done has helped, but this could’ve been one of those years. It was a little cooler week and I think that’s an important factor, too. With the heat and stress, the ponies start sweating and they lose electrolytes,” said Dr. Cameron. He said, “The firemen spot mares in trouble during round-up which puts some stress on them. That’s not their normal routine.” “They’re usually mares with older foals that are taking a lot of milk. Then, it’s the hottest week of the summer very often. You combine the stress, the heat and boom, it pushes them over the edge,” said Dr. Cameron.
These dietary supplements are the result of Dr. Cameron’s research. “I consulted with Dr. Julia McCann from the VA/MD Regional College of Veterinary Medicine located on the VA Tech Campus and Dr. Vivien Allen from Texas Tech,” said Dr. Cameron. The manager of the Federal Park also emailed Dr. Cameron a copy of a study that was done by the Maryland Department of Agriculture of the native flora of Assateague Island, which he sent to Dr. Allen in Texas.
Dr. Cameron and his experienced team of vets offer a full lab, pet surgery, a pet pharmacy, in-hospital surgery suite, in-house x-rays, ultrasounds, a closely supervised hospitalization area, indoor boarding kennels, a pet spa for grooming as well as other pet services, all at the hospital in Painter. The hospital maintains a well developed website, www.esanimalhospital.com
Also on the staff at the hospital are Dr. Paula Cameron, Charlie’s wife, Dr. Nuno Carreiro and Dr. Cynthia J. Johnson-Larson. They have all contributed to the grown of the hospital which may be the largest animal facility on the Shore. (See separate story.)
Aside from the Chincoteague ponies, the doctors do make house calls. “Occasionally, someone will trailer in a pony, but most of the horse work we do is on an ambulatory basis. We go out on the truck to their place,” said Dr Cameron.
In discussing the Chincoteague ponies, “I think the Chincoteague ponies are more hardy and brave. They’re basically survivors. They’re tough and their dispositions are gentle, which is why I think they work well as children’s ponies or horses,” he said. Overall, the ponies are not high strung and dangerous. There are exceptions. There are a few you have to watch out for,” said the doctor.
Dr. Cameron’s parents owned two Chincoteague ponies when he was less than five years of age. His father would lead him around in an old Army Calvary saddle. These ponies lived to be about 30.
At the spring and fall round-ups, Dr. Cameron gives the Chincoteague ponies their vaccinations, checks them over and gives them de-worming medicine which is taken by mouth.
Mares are pregnant for about 11 months. The Chincoteague pony foals are sold at the annual auction held on the very last day of pony week at the Chincoteague firemen’s carnival grounds on South Main Street.
Roundup weekends are demanding for Dr. Cameron and his staff as well as the Salt Water Cowboys. The routine is almost always the same. Late Friday the riders report to the western edge of the southern herd grazing compound, spread out and and move those ponies along to a holding corral off Woodland Trail. When all the ponies are in the Cowboys run them across Woodland, through the woods and marsh where they enter the corral area from the back side.
Dr. Cameron’s work begins early Saturday, usually right after breakfast at Bill’s Restaurant. The rear of Dr. Cameron’s truck is set up like a mobile pharmacy.
The pen, where he treats the Chincoteague ponies, is divided in half by a fence. This separates the ponies that have been treated from those that haven’t. There is space to move around that keeps the ponies comfortable until Dr. Cameron is ready for them.
While Dr. Cameron is getting ready, various helpers chase the ponies into the other half of the pen. One by one the ponies are run through a chute, and then into a wooden stanchion that allows for little movement. Once in the stanchion, an assistant to Dr. Cameron will take a wand and wave it around on the left side of the pony’s neck. The wand actually reads a micro chip put in their neck so Dr. Cameron will be able to identify which pony they are working on.
When they find the micro chip, numbers and letters will appear on the screen.
Next, Dr. Cameron, with the help of an associate, opens the pony’s mouth and place a metal tube near the back of the throat where there is a place with no teeth. He inserts a worm pump, or a long metal tool called a liquid drench. He will inject the medicine by pushing a handle pumping it into the pony’s mouth.
When the pony has swallowed the medicine the assistant will open the front of the stanchion that leads to the other side of the pen. They will repeat this procedure until every pony has been treated.
Dr. Cameron finishes his work on the southern herd by about 9:30 a.m. Then it is time to load up and move much further into the wilderness of Assateague Island to the pen that will later that morning hold the northern herd.
When the southern ponies are released back to their range, the Cowboys are already rounding up the northern herd, numbering 50 to 60 ponies more than the southern group. They do not bring this herd to the same pen; the northern herd’s pen is located nearly four miles out on a service road. The only way to get out there is to walk, unless you are part of the veterinarian’s crew or one of the cowboys. Then it is accessible by vehicle or horseback. In recent years, however, Lou Hinds, manager of the Refuge, has made available a bus that visitors can take to the northern corral.
Word of warning. If you plan to hike, bring plenty of bug spray. In warm weather the flies, mosquitoes and poison ivy are plentiful. And bring along your camping skills. There are no bathrooms.
The Salt Water Cowboys, as they are known, are nearly as famous as the ponies. They come not only from Chincoteague but from nearby communities. The roundups mean early days for these men who begin loading their own horse trailers and moving to their meeting point in darkness.
The northern herd is wilder then the southern herd so it’s harder to give them the medicine. When the cowboys get the ponies into the stanchion and Dr. Cameron tries to open their mouth they will kick the back of the stanchion and try to put their heads out of reach of the assistant’s hands. Not only is it dangerous for the people inside the pen that are helping get the ponies into the chute, but it’s also dangerous for Dr. Cameron and his assistant. If the ponies get really riled up, they will turn around and charge at the people. Dr. Cameron has been bitten and kicked in his years of working with the ponies.
Sometimes when a stallion has been given his medicine and has been moved to the other side, he will stand and wait for his mares to come out. He will count them making sure that each and every one has returned to where they need to be, with him.
