Personal comment: The dangers and consequences of pet obesity.

Transcript of personal comment from this episode of The Web-DVM:


For my personal comment tonight, I will be addressing an unnecessarily common health issue in dogs and cats, and that is the epidemic of obesity. So if your cat looks like this (see video for image), or your dog looks like this (see video for image), you especially need to pay close attention to what I have to say.

Obesity and the lifestyle that supports it, overeating, the consumption of excess carbohydrates and fats, and being sedentary, causes pets a world of secondary health problems. From a metabolic standpoint, the obese patient is predisposed to life threatening bouts of disease of the pancreas, as well as insulin dependent diabetes. Fat cats especially love to get diabetes, comprising the biggest percentage of diabetic patients in small animal medicine.

From a musculoskeletal standpoint, obesity leads to spinal disc injuries, ligament tears, and early age arthritis due to excessive stress obesity causes to these structures. I have one particular West Highland White Terrier patient that resembles a foot stool she is so fat, that for the past 3 years, literally wobbles her way into my clinic because her obesity decreases her ability to ambulate normally. This Westie now has to come in for regular rehab laser treatments for her knees because her obesity is wearing them out at only 5 years of age.

The owner of this Westie, as is the case of many owners with obese pets, has maintained that he does not over feed her, offering her only the diet food that I prescribed, in the amounts I recommended. I even ran bloodwork on her and checked her thyroid levels to make certain there was not underlying medical disease contributing to the dog’s obesity, which all returned normal; confirming that this owner is lying to me, that this dog is getting overfed despite his protests that this is not the case.

You see folks, animals like people, when overfed gain weight, and when fed less, lose weight. One does not need a veterinary degree to figure that out. So when I have ruled out all known medical causes for obesity, prescribed a weightloss diet that your pet responds to by getting even fatter, you are lying to me and not following my instructions.

With the owner of the fat Westie, it was his wife that ultimately ratted him out, explaining to me that her husband indeed feeds the recommended amounts of the weightloss diet I prescribed, but also continues to offer the dog a portion of whatever he is eating, whether it be bacon, steak, potato chips, or even iced cream!

So because this owner cannot resist his dog’s begging, to date it has cost him $140 in bloodwork, $360 in laser rehabilitation treatments and $150 in anti-inflammatory drugs for the bum knees. The dog’s quality of life is compromised because she is so bloated that she cannot move, and at this rate, her life will surely be shortened.

Ladies and gentlemen, this is just one example of a virtually endless number of patients that have a similar story. Why owners at a huge cost to their pet’s health, as well as their bank accounts, just cannot say no to their pets and ration their eating, is beyond me. I even had one owner tell me that he will never get weight off his dog because, like his own personal approach to life, he would rather let him eat what he wants, live a shorter life and die happy, rather than go through life unsatisfied and live longer.

To that, my reply is this:

Your dog’s life will indeed be shorter, but he will not die happy. On his way to the end of his life that you have decided to hasten, he stands a far greater likelihood than other non-obese pets, of needing surgery to repair ligament tears or spinal disc herniations. Along his shortened journey of life, he may have to be hospitalized for pancreatitis or need to receive insulin injections to manage his diabetes. He may have his vision compromised from diabetic complication of cataracts or because his obesity is causing his body to deposit cholesterol on the corneas of his eyes. And if he survives all of that, at some point, the decision to put him to sleep will ultimately be made because his obesity has stressed his joints to severe level of degenerative disease, the pain of which, all the medications in the world can no longer manage.

Sounds to you like a crappy way to live? Of course it does! So if your pet is fat, take it seriously and start getting some weight off. To help you in your task, I will be posting some general feeding guidelines, as well as some good choices for weightloss diets on the blog, at webdvm.blogspot.com.

That is our show for this Thursday, February 18, 2010. Please help us continue our discussion at our blog at webdvm.blogspot.com. As always, comments posted there will be addressed by me live on my supplemental show Sunday evening at 7:30 PM EST at BlogTV.com. Please join me next week, as I will be discussing heartworm disease in dogs and cats. Is it really that bad of a problem? Can cats get it too? Find out next week.

Supplemental Information:

How do I know if my pet is overweight?


Begin assessing your pet’s body condition by simply looking at him. Viewed from above, you should see a noticeable “waist,” which in dogs and cats is a modest tapering just past the rib cage. No visible waist (or the opposite – a pouching out or pear shape) is an indication that the pet is overweight.

Viewed from the side, as your eyes from the chest toward the back end of the dog just past the rib cage, the abdomen should be tucked in. Lack of this (or the opposite – a pot belly) is an indication that the pet is overweight.

(Ideal appeareance)





Run your fingers across the rib cage. You should be able to feel individual ribs. While you should never see rib protrusions, you should always be able to feel them beneath the skin. If you cannot feel ribs, that is an indication that your pet is overweight.

So how do I get weight off my overweight pet?

If your pet is just mildly to moderately overweight, I would begin by simply calculating the daily food intake to make certain that you are not overfeeding. The general guideline that I offer for dogs and cats is one 8 oz cup of food per 20 pounds of body weight per day. Since different foods have different caloric content, this guideline is general, but usually fits fairly well with most normal pets and with most diets. If you are already feeding this much or less and your pet is overweight, try cutting back what you are currently feeding by about 25%, as well as try to increase exercise. In doing these calculations, be sure not to use the pet’s current weight, but the target weight which you or your veterinarian feel would be ideal.

If your pet is substantially overweight and/or the above measures have not helped, then you should select a weightloss diet. Commercially, Science Diet, Eukanuba, Iams, and Royal Canin all make excellent weightloss diets for both dogs and cats. If I had to pick out one of these diets as my favorite as far as most effective, the Science Diet light formulas have historically seemed to be the best in my experience. You would feed these diets under the same 1 cup per 20 pounds per day guideline.

If your pet is morbidly obese and/or even these good commercial weightloss diets have not helped get weight off your pet, then it is time to consider a prescription weightloss diet from your veterinarian. Each vet has his/her own favorite lines of prescription diets, so ask your vet which one he/she recommends. I am a big fan of Hills R/D for this purpose. With these stubborn weightloss patients, it is also a good idea to have the thyroid checked to make certain that hypothyroidism, a.k.a., underactive thyroid, is not getting in the way of proper weightloss.

Okay,

I previously posted about my lab with elbos dysplasia. Well, he's also overweight, which I now is not good with his condition. I have feed him R/D and fed the recommended amounts and NOTHING MORE! I am not like your client in the video that gives tables snacks, not for him, not for any of my dogs.

Yet, he has not lst even an ounce in 2 months. He is 5 years old. Any advice??

Hey doc, where is that beack background sunset scene you always have behind you n your vids. Is that where you live?

Scott said...

I am a pet store owner and am completely appaled by this legislation being passed against the sale of dogs and cats in pet stores. Who is the government to tell us who can and who cannot sell puppies and kittens to a public that want them?

This is Nazi bullshit, and I hope this law has no legs beyond the borders of tree hugging California!

Janna said...

Doc, you look young to be a vet. How long ago did you graduate?

Gail said...

My little chihuahua mix is fat says my vet and just about everyone I know. But, he is very finicky and won't eat any of the weightloss diets my vet recommends.

Do you know a one that he may like better?

My cats weight goes from 11 to 12 lbs... He is 5 yrs. old and in less than a year went from 6 to 11 lbs. (age 3) after being neutered and my free feeding him -- what I now know was a BAD choice name brand food... His Vet of course gave me the lecture of potential diabetes and heart disease, if I continued to free feed, etc. and told me to switch him to a senors diet... Well I feed him a high end cat food and according to the directions and hes not losing weight (he won't eat any other types of food, just dry cat food -- so he doesn't get treats) and at his yearly checkup he hadn't gotten heavier so the vet said to continue what I am doing and didn't mention him being tested or anything... I've noticed that sometimes when my cat is sleeping he sounds like he is weezing and think it could be contributed to his weight... And he glups down water... What do you think I should do?

Hey Doc,

No offense, but did you have a few cocktails or smake a fatty before this latest blogtv show? You just seemed not quite yourself, a little...off.

No worries though - loved your answers as always, they were just delivered...differently.

Thanks for the tips!

Jenni,

You just missed out on having me address your question live on BlogTV. In the future, try to get your comments in before Sunday evening each week.

However, happy to still give you some help. My suggestion would be to not just rely on high end cat food at this point, but to consider an actual prescription weightloss diet.

Probably my two favorites for this purpose are Hills R/D and Purina DM. If you feed these no more than 1/2 a cup per day, within 30-60 days, you will very likely see some weightloss.

Your vet should be able to order these for you and they both come in both canned and dry forms.

PW, bluntly honest as always, you are right, I was off, but not because of preshow dubbage or drinking (give me some credit, man, I am a professional!). I am battling a stubborn flu and had taken some Nyquil a while before my broadcast - clearly underestimating how much that stuff throws me for a loop! The directions say to avoid operating heavy machinery after use - they should also add, do not do a public broadcast after use! LOL!

Thank you for this great article on pet obesity. I have a real 'pet' peeve with overweight, uncomfortable pets and the related unnecessary health risks that can be so easily avoided. I wanted to let you know about this new pet-friendly scale that they weigh themselves on, as a simple tool to keep an eye on your pets weight as it is easier to maintain proper weight than it is to implement and keep our furry friends on a diet regimen. I was hoping you would mention it as an option to everyone out there trying to figure out how to keep their pet fit, trim and healthy. It can be a real challenge and I am hopeful that this product will promote good health for more pets because of its ease of use.
Thank you for taking such good care of our furry friends,
Judy (NY, NY)
