Feed for…

Physiological state: Maintenance, growth, gestation, lactation, work, geriatric

What type of protein is most available

Animal protein compared to plant protein

kleiber equation

• < 2 kg and > 45 kg Body Weight

  • 70 Kcal X BW(kg)^0.75

• > 2 kg and < 45 kg Body Weight

  • ⁃ 30 Kcal X (BW(kg) + 70)

Atwater equation 

• Protein: 4 kcal/g 

• Carbohydrates: 4 kcal/g 

• Fat: 9 kcal/g 

How to feed dog

• Adult – Feed 1-2 X/day

• Puppies – Feed 2-3 X day

• Geriatric – Feed 2-3 X day

• Giant Breeds- Feed 2-3 X day

bones

Rate of maturity

Toy breeds- 9+ months

Large/ giant breeds- 2 years

Large dogs are prone to

Torsion- twisted gut

Extruded Dog food

Filled with air, cause torsion, add die- pattern

Feeding large breed puppies

No adlibidum- eating however much when you want

avoid exercise after eating

time feeding doees not work

grow slower than smaller breeds
