Obesity

New Life for an Old Dog

/ Dr. Christine McFadden / Leave a comment

She had been all black in her youth, but now at the age of 14 she is showing some gray around her muzzle. She used to jump and romp and play. Now she walks sedately across the yard, a faint weakness in her hindquarters. But always, Bella has class. Always, the gentle tail wag to let you know that she’s listening, she’s here.

Two years ago, Bella exhibited marked signs of difficulty when she tried to stand up in the morning. Upon examination, it was obvious that she was losing feeling in her back feet. Our X-rays showed degeneration of the spine in her back. We discussed options and Bella’s owners decided to see a specialist, where Belle underwent laminectomy spinal surgery. She recovered beautifully and even though she needed to stay on arthritis medications she moved quite fluidly again. Bella enjoyed her people and her life.

Bella is a Labrador Retriever, and though I don’t believe she has ever retrieved anything more interesting than a goodie from her owners’ hands, she shares a fate common to many Labs. Bred to be high energy dogs, capable of hunting all day and swimming in frigid waters to retrieve ducks, these dogs seem to naturally have an extra layer of protective fat. Given snacks and a soft life in the suburbs, many a Lab will put on a few extra pounds.

As I surveyed Bella in the exam room on Tuesday, I felt a deep unease. By no means obese, Bella could have stood to “lose a few” but not like this – Bella had lost 10 pounds over a two month period of time. Nothing in her diet or routine had changed, though her owners noted that she frequently passed a soft stool. Given her weight loss, I recommended that we start with a blood panel for diagnostic tests. Her physical exam was unremarkable for her age and existing medical history.

When the lab tests returned, the “biggies” were all good. No sign of diabetes, liver and kidney function within normal limits. Her body proteins were low. Hmmm.

Bella’s body either wasn’t making proteins or it was losing protein. In this case, with further testing, we were able to verify that she wasn’t losing protein in her urine, and that her small intestine wasn’t absorbing nutrients properly (her cobalamin levels, or vitamin B12, was too low). Of course, we knew she had chronic diarrhea, so it was only a small step towards the diagnosis of a protein-losing enteropathy, or PLE. Plowing ahead, what was the underlying cause of THAT? We asked that Bella return for abdominal x-rays and ultrasound. While corroborating thickened bowel loops, we also found a mass on her spleen. We didn’t know if that mass might be cancerous or not, but we hadn’t found any other signs of cancer and dogs can get along without their spleens very nicely. If it wasn’t cancer but a hematoma on the spleen, there was a risk of it rupturing and Bella bleeding to death. After several talks, we scheduled Bella for surgery. She would undergo a splenectomy to remove the spleen and have her intestine biopsied to confirm the cause of her PLE.

This was a lot to ask of an old dog. Bella was in surgery for over an hour, requiring her to lay on her back, not a terrific position for a dog that had undergone major back surgery. Positioned in a foam support tray throughout, I still worried. Surgery was successful and her recovery from anesthesia rapid.

We kept her on intravenous pain meds, but there was no denying that Bella was slow to “bounce back”. Her owner cried that first day. Because of her IV fluids, Bella couldn’t move around easily. She struggled. We disconnected the fluids to take her outdoors to walk in the sunshine. Pain medication can cause a loss of appetite. I hand fed her. We slowly decreased the pain meds and upped her recreation. On Day four post-op, Bella met her owner in the parking lot. Moving slowly, she walked over to her, tail gently wagging. Bella went home. Her biopsy report diagnosed Inflammatory Bowel Disease (IBD) which responded well simply by feeding a specialty diet. The diarrhea disappeared. Her spleen was cancer free. Bella was on the road to a full recovery, as classy as ever.

Weight Loss Dreams

Myrtle had lost 8 pounds. I was most impressed. A middle-aged Australian Shepherd, she’d never had puppies, so couldn’t excuse her mid-life spread by pointing out her gorgeous offspring. Myrtle had been spayed young, which virtually guaranteed that she would not contract breast cancer in her lifetime (a 1-in-4 risk for older intact female dogs). This also meant she couldn’t drum up excuses about hormonal changes late in life. No, sadly, Myrtle would garner no awards for discovering the mystery behind unwanted weight gain : too many calories in, not enough burned off. In short, Myrtle over-ate and slept in. “Exercise” was not in her vocabulary.

 

When you realize that she had stuffed 73 pounds into a 50 pound body frame, you might begin to understand the concern. A young dog that is overweight can usually bear the extra pounds with grace. They are active, if perhaps less agile than a truly fit play mate. But look ahead : after years of joints and body parts groaning under those extra pounds, you will find this same pet to be suffering from arthritis at a much younger age than its counterparts. The overweight dog faces their senior years plagued with creaky knees and groaning hips. Yes, we have bunches of medications to come to their aid – an arsenal of anti-inflammatories, analgesics (an analgesic is a straight pain medication that is meant to mask the pain but does nothing to change the underlying condition, does not reduce inflammation, etc), dietary supplements, omega this and that – and they work. They do. But NO pill helps a suffering obese dog as much as taking that extra weight off. The weight loss can’t reverse the damage already done, but it will significantly reduce the everyday burden and muscle strain required to move the body.

 

As a group veterinarians are seeing obesity with increasing frequency in pets of all kinds. Diabetes mellitus (sugar diabetes) is on the rise, as are heart disease, exercise intolerance and heat stroke.

 

We feed our dogs too much, too often. I would like to think that the man who assured me he fed his dog only doughnuts was kidding. I understand the desire to share food with those we love. At our veterinary clinic we stock a low cal treat in each exam room. They gum up like rice cakes and average about 3 calories each. No, I don’t suppose anyone would chose it over bacon, but my patients on the whole accept them. The Disney stickers we used to hand out were a little dry going down. We serve treats because we hope our patients have a pleasant experience. We understand what you’re going through.

 

When meeting a pet who desperately needs to lose weight, I try to review the actual diet as fed at home. There have been some surprises over the years. Dental chews help keep teeth healthy. Bonus! Because most people do not brush their dog’s teeth. But we found some of those chews had up to 50 calories each – which for a tiny dog leading a “lapdog” life could account for 1/5th of their total recommended daily caloric intake! Dog food companies have been slow to publish the calorie count of many of their foods. If found, it will read as “Kcal” or kilocalorie, which is the same as “calorie” in everyday life.

 

So-called “lite” or healthy-weight or weight-management diets can have widely varying calorie counts. Get that information, calories (Kcal) per cup, before choosing which food is best for your pet. Extra fiber will fill up the stomach, helping your dog feel satisfied with smaller meals. Your veterinarian is always there to help. Blood tests can be checked to rule out underlying health issues, and we offer assistance with prescription weight loss foods and plans that really work – if followed.

 

We strive for balance. As long as we count the gummy bear and the cocktail peanuts, we can help you make the life plan work. Because at the end of the day, the real reward is talking to Myrtle’s owner and hearing her say in wonder : “It’s as if she’s 2 years younger. I’m getting my dog back.”

Would anyone be interested in starting a gym for dogs? Instead of tight shorts and weight lifting equipment we could sponsor sequined collars and encourage exercises like the “biscuit stretch”.

In todays’ world the working dog is almost a thing of the past – the majority of our pets have only to fight their way out of bed in the morning to get to the food bowl. For many of them, grateful to get a daily walk, the widely promoted high protein foods are not necessary. An incessant bombardment of dog jerky and canine biscuits, table scraps and cocktail peanuts “rounds out” many a pets daily diet….and doesn’t do much for their health.

They waddle in. Some of the smallest breeds can still be carried in. A few you expect to see float in, sort of doggie balloons propped above toothpick legs like the carnival mans’ balloon-on-a stick. The owner usually aw-shucks, Doc, we just love her (or him) so much.

You’re going to love them to death.

Yes, dogs have problems like high cholesterol, fatty liver disease, pancreatitis, heart disease and joint degeneration (arthritis) related to obesity. The rise of diabetes mellitus or sugar diabetes  in dogs and cats has alarmed veterinarians across the nation and is believed to be partly attributable to overweight conditions. Every pet that comes in for an exam is now recommended to receive a Body Condition Score (BCS), meant to sound an alarm if the pet is too heavy or, rarely, too thin.

So let’s discuss fat. Fat is looking at your dog and not seeing the curvy indentation in front of the rear legs and hips that we call a “waist”. Fat is groping over your dogs’ chest searching in vain for a rib. Fat is obvious. Deciding on the correct weight for your dog is less obvious. I recommend to take a few pounds off and look at your dog. It can be that simple. One guideline is the ability to feel the ribs easily, with a thin layer of fat covering them.

How to take the pounds off? The secret will disappoint you: less calories, more exercise. On a weight reduction program your dog can lose up to 1 pound a week. Toy breeds may set a goal of 1 pound weight loss per month. Your veterinarian can guide you safely in this area. It is true that some dogs can suffer from thyroid gland disorders that predispose towards obesity. Some medications can cause weight gain as a side effect. Older dogs may have health problems that preclude dieting. For these reasons dogs with severe weight problems or on medication should be examined first by their veterinarian.

One of my favorite success stories was watching a 45 pound dachshund reduce to a healthy 22 pounds. She did require the aid of a balanced prescription reducing diet, but she came through with flying colors! She acted years younger, cavorting around, full of pep and energy. Her family was wonderfully supportive, despite an embarrassing incident. At the height of her diet, the owners of Greta entertained their minister to a small luncheon. Conversation flowed, congeniality reigned. Suddenly the jaws of the Dieting Dachshund lept out, snatching the ministers’ sandwich from his very lips. Just as quickly she disappeared again. Shaken, the good man left soon after. Word has it that she never repented.
