Obesity in Cats and Dogs

Obesity in dogs and cats

What is obesity?
Obesity is defined as an excess of fat tissue in the body and is the number 1 nutritional disorder in animals. One of the most common ways to assess obesity in animals is by using a body condition score (BCS). Animals who carry excess fat tissue in their body are classified as either 1) overweight (5-15% excess body fat) or 2) obese (>15% excess body fat). Did you know that a large percentage of owners report a normal body condition score, when, in fact, their animals are overweight?

What is a body condition score?ObesityDog

A body condition score is a visual and palpable way of assessing whether an animal has an ideal body condition. Three main areas are used to assess
a body condition score are:

1) subcutaneous fat overlying the ribcage,Obesitydog2

2) abdominal fat and subsequent presence/absence of “tucked” waist (viewing from the side and from above the animal),

3) assessing
subcutaneous fat overlying the spinal processes

Most commonly, a 9 scale score chart is used, with both BCS = 4 and BCS = 5 being ideal. Sometimes, a 5 scale score chart is used, with BCS = 3 being ideal.

 

Risk factors associated with obesity
1. Spaying/neutering your animal - decreases natural hormones found in the body that vamp up the metabolism
It is very important to calculate an appropriate amount of food for your animal’s activity level and spay/neuter status. ASK US to see how many kilocalories your animal needs!
2. Lack of activity - taking your dog for daily walks and playing with your cat at home can help maintain an ideal body condition
3. Certain illnesses - for example: hypothyroidism, diabetes, Cushings
4. Dietary factors - it is important to feed your pet a balanced diet that meets their nutritional requirements

ASK US if there is an appropriate diet that we recommend for your pet!

  • As much as we all love to feed our pet treats, only 10% of their daily calorie intake should be from treats. ASK US to help you calculate how many treats you can give on a daily basis!

5. Certain drugs - for example: steroid supplementation

 

 

Common diseases associated with obesity
1. Metabolic disorders - for example: insulin resistance/glucose intoleranceArthritisObesity
2. Endocrine disorders - for example: Cushings, hypothyroidism, diabetes
3. Orthopedic disorders - for example: osteoarthritis, intervertebral disc disease
4. Cardiorespiratory disorders - for example: tracheal collapse, laryngeal paralysis
5. Urogenital disorders - for example: bladder stones, urinary tract infections
6. Certain cancers - for example: mammary cancer and transitional cell carcinoma
7. Other disorders - for example: high blood pressure, decreased immune function, increased anesthetic risks, exercise intolerance

 

 

 

What can I do to help my pet maintain an ideal body weight?ObesityExercise
1. Feed your pet the correct amount of food - ASK US to calculate food requirements for you
2. Restrict treats/table scraps
3. Exercise/play with your pet
4. Feed your pet a balanced diet suitable for his/her lifestage - ASK US what diet is appropriate
5. Behavioural modification - ASK US for some tips on limiting begging behaviours
6. Have routine weigh-ins - come into the clinic for a treat and weigh in at no cost to you!

 

 

 

 

Fun fact: did you know that dietary restriction can increase your dog’s lifespan? A study using labrador retrievers showed a median lifespan of 13 years in the dietary restriction group vs. a median of 11.2 years in dogs overfed. That is a difference of almost two years(!!!) simply by feeding the correct amount of food and maintaining an ideal body condition score in your pet
