Be evidence based Be well informed & good communicators Be the pet’s advocate always Make a specific recommendation Ask the tough questions!
Be a practicing scientist Share CE “Pearls” Share resources Listen & learn Take a preventive approach
Preserve the bond They want their pet to live a long time Want us to respect their choices/values Preventive approach Control costs
What are you currently feeding? Are you happy with the food? How did you decide on that food? Does he/she seem to enjoy it? Other pets in house? How is stool quality, any vomiting etc?

Periodontal disease causes kidney, heart, and liver disease (and others) and is 100% preventable.
Is periodontal disease Associated with systemic & distant-organ* abnormalities?Yes: There are proven associations between periodontal disease and systemic and distant-organ abnormalities.7 Two studies conducted in dogs demonstrated that microscopic inflammatory or degenerative changes in distant organs (kidney, liver, heart) increase with rising severity of periodontal disease,8,9 and 2 studies have demonstrated an association between periodontal disease and cardiac10 or renal11 disease, though the extent of periodontal disease in these studies10,11 was recorded inconsistently.

If pet is 2 BCS scores over ideal on BCS or more than 20% over ideal weight a prescription food high in protein should be used
Dogs 1 gm protein per lb of Ideal weight Cats 2 gm protein per lb of ideal weight
85 lb lab whose ideal weight is 60# has a BCS of 8 needs 60 mg protein daily to get to 60#.
A 13lb cat whose ideal weight is 10 lbs and a BCS of 7 needs 20 mg protein daily to get to 10# safely.
Dear Colleagues,
I wonder if the group can help us with some challenges related to the best evidence related to what really works with our current Rx diets and exactly why they are better than OTC foods for pets that are 20% more than their ideal weight.
What we are hearing from 2 major pet food companies is that it is simply the protein that works because it is muscle sparing, satiates & burns more calories while another company claims that the lysine &/or Carnitine levels are more important.
We have primarily been using the 1 gram of protein per lb of ideal weight for dogs (and 2 gm per lb for cats) as presented by Dr Julie Churchill at U of M and using the evidence based summary from JAVMA by Dr Phil Roudebush from 2008.
Thanks much!

From a nutritional perspective, the concern with feeding any over the counter food for active weight loss is that when you restrict the amount of food fed to decrease energy intake, you are also restricting other essential nutrients such as protein, amino acids, fatty acids, vitamins and minerals.
Over the counter foods are generally designed to provided appropriate amounts of essential nutrient for pets maintaining their body weight, and when restricted levels are fed, essential nutrients may fall below adequate daily intakes.
Prescription weight loss foods and over the counter foods designed for active weight loss take this into consideration and boost dietary protein as well as other important essential nutrients to help ensure that protein and other essential nutrient needs are met during caloric restriction.

Impellizeri JA, Tetrick MA, Muir P J Am Vet Med Assoc. 2000 Apr 1;216(7):1089-91.
“Effect of weight reduction on clinical signs of lameness in dogs with hip osteoarthritis.”
Results—Dogs (9) lost between 11 and 18% of initial body weight. Body weight, body condition score, and severity of hind limb lameness were all significantly decreased at the end of the weight-loss period.
Conclusions and Clinical Relevance—Results suggest that in overweight dogs with hind limb lameness secondary to hip osteoarthritis, weight reduction alone may result in a substantial improvement in clinical lameness. (J Am Vet Med Assoc 2000;216:1089–1091)
Rousch J K et al “Evaluation of the effects of dietary supplementation with fish oil omega 3 fatty acids on weight bearing in dogs with osteoarthritis” JAVMA Vol 236 No 1 Jan 1, 2010
Results—Dogs (129) fed the test food had a significantly higher serum concentration of total omega-3 fatty acids and a significantly lower serum concentration of arachidonic acid at 6, 12, and 24 weeks. According to owners, dogs fed the test food had a significantly improved ability to rise from a resting position and play at 6 weeks and improved ability to walk at 12 and 24 weeks, compared with control dogs.
Conclusions and Clinical Relevance—Ingestion of the test food raised blood concentrations of omega-3 fatty acids and appeared to improve the arthritic condition in pet dogs with osteoarthritis.

Hands down the toughest question a client can ask us!
Marketing challenges Anthromorphizing “Over animalizing” What is the truth?
FDA & AAFCO regulated Is a legal document
Manufacturer’s info Ingredients list in order of weight (Salt is divider between major & minor) Guaranteed analysis Feeding directions Nutritional adequacy statement Meets nutrient profiles or Feeding Trial Statement
Calories per cup EPA per cup Perna, Glucosamine & chondroitin
sulfate per cup Quality of Ingredients Organic
Grains (corn, wheat & soy) By products Rendering, preservatives, digest
opponents proponents
corn filler poor protein source poorly digestible causes allergies
corn meal is good source of protein
soy cheap source of inferior protein
Fine if used w/ complementary grains
wheat allergenic not allergenic
Link to aflatoxins? Allergies? Filler? Link to high fructose corn syrup? Marketing spin?
An ingredient that has no nutritional purpose
better nutrient balance than other grains
highly available CHO source good linoleic source essential amino acids fiber source Not a common cause of allergies
Soybean meal excellent source of lysine & tryptophan
NOT highly allergenic (6% of allergies to 36% for beef)
Doesn’t cause bloat
Incidence in people _?_% Incidence in pets 1.6%? Irish Setters 1990 study
Poultry by product meal 65 to 70% Chicken meal 63 to 67% Fish meal 60 to 65% Corn gluten meal 60 to 64% Meat & bone meal 50 to 55% Soybean meal 46 to 50%
Wild canids are not apex predators (like wolves) they are more like coyotes and ate small prey, insects, mollusks, carrion, and plant materials (berries, fruits, nuts, seeds, roots, grass, seaweed, gut contents of herbivores)
Grains have a higher consistency of amino acid quality than meat protein (e.g. lamb has poor methionine & taurine)
Make sure a meat protein is in the top three ingredients
As long as amino acid needs are met grains are fine
Ingredients not used for human food
Includes liver, spleen, tripe etc Does NOT include hair, hooves etc
The animal feed industry has always used the by products of the human food industry
High variability in quality esp meat by products
Source of considerable marketing “spin”
Non-rendered, clean parts other than meat derived from slaughtered animals. It includes but is not limited to lungs, spleen, kidneys, brain, livers, blood, bone, partially defatted low temperature fatty tissue, and stomachs and intestines freed of their contents. It does not include hair, horns, teeth & hooves.
(This does not include backs, necks, and chicken “racks”)
Rendering = cooked & processed into meals Digest = similar to bouillon, sprayed on for
palatability
Rendering is presently a “necessary evil” ofconverting waste from human food processing(meat & plant) into usable items to feed toother animals. According to “Feed Your PetRight” authors it needs much more regulation.
“Besides, the pet food industry serves an important ecological function by using up food that would otherwise be thrown out,”
“If everyone cooked human food for the 472 million cats and dogs in America, it would be like feeding an additional 42 million people.”
Dr. Nestle author of “Feed Your Pet Right”
quoted in NY Times article.
Probiotics are killed by heat Fish oils decrease the shelf life of food Value of Prebiotics?
Urolithiasis Cats & Dogs Protein quality/inflammatory bowel disease
Cats May help satisfy pets to lose/maintain weight Cost, environmental issues, etc Dental benefits of dry?
Do you have a veterinary nutritionist on staff?
Are they available to answer questions? Which of your diets are tested using
AAFCO feeding studies? What specific quality control measures
do you use to assure consistency & quality?
What kinds of research on your products has been conducted and are results published in peer review journals?

Dogs with chronic renal disease (less than 1% of all adult dogs) may benefit from restricted levels of protein & PO4
Zoran D, Buffington T “Effects of nutrition choices and lifestyle changes on the well being of cats, a carnivore who has moved indoors” JAVMA Vol 239 No 5 Sept 1st 2011
Protecting them from their natural predators (larger carnivores and primates) and providing preventative medical care to decrease their risk of illness from infectious diseases has increased the average lifespan of cats from 4.5 years (which is typical of an outdoor cat) to nearly 15 years.7 However, despite these benefits, this crepuscular carnivore has been removed from a free-roaming, active existence to a captive, indoor, sedentary one.
Cats have gone from frequent consumption of small meals that consisted of animals they could catch and kill to consumption of prepared diets of human choosing, which are often available in excessive amounts and consist of less protein and a wider variety of protein, fat, and carbohydrates than is found in wild birds, insects, and small rodents.
Cats are one of the few true carnivores humans have attempted to domesticate. People also have attempted to get cats to adapt to human lifestyles and preferences, which sometimes leads to a failure to recognize or understand the perils of domestication and its effects on feline behavior, well-being, and health. As a result, there is increasing evidence that many of the chronic health problems of domestic cats are directly or indirectly related to nutrition or lifestyle changes that have been imposed on them by their owners
Prebiotics/probiotics Role of protein in inflammatory bowel
disease Obesity Osteoarthritis Renal disease FLUTD
Small, firm and dark Trial & error What works in one pet will not always
work in others Give several options Can always re-evaluate & change
Cost of pet foods Missing ingredients (antioxidants,
enzymes, vitamins like Vit E, probiotics) Recalls, Treat contamination
Earlier publication of studies from pet food companies in peer reviewed journals
Better FDA regulations (calories and EPA levels per cup on label, get rid of food families, etc)
EPA at 40mg/kg in every pet food Less “negative” marketing More good studies supported by
independent groups like ACVIM, ACVN, AAFP, AAHA, AVCSM
Protein levels approaching wild diet Anti-inflammatory levels of EPA Probiotics & prebiotics at optimal levels Evidence based joint protectants added Organic and no preservatives or by
products Inexpensive & convenient to feed!
