Practice Scenario

Meet Herman, a young adult, large-breed dog with occasional hindlimb lameness and reluctance to play.

Meet HERMAN

A 15-month-old, intact male Weimaraner

  • Herman presents for hindlimb lameness. The owner reports the lameness typically occurs after long walks and games of fetch. Occasionally Herman will stop and refuse to walk or play any longer. He also seems stiff when rising from a down position and climbing in and out of the car.
  • Herman eats a mixture of dry puppy and adult food topped with a few bites of raw steak. The owner is unsure of the brand but says that the puppy and dog food are not labeled for large-breed dogs. The owner also gives Herman a calcium supplement daily.
  • Herman has a body condition score of 5-6/9, weighs 36 kg (79 pounds), and has normal muscle mass.
  • On exam, he appears to resist hip extension on both sides. However, he is very excitable and thus his reactions are somewhat difficult to interpret. He appears otherwise healthy.

Feeding Philosophies

Considerations When Feeding Raw Pet Food Diets

Although raw meat diets are popular among some pet owners, there is no scientific evidence that they provide any specific health benefits other than being highly digestible. In fact, raw pet food diets may present several major health risks.

Key Messages


  • Raw meats, poultry and fish, including those intended for human consumption, can be contaminated with disease-causing bacteria such as Salmonella or E. coli. These bacteria can be harmful to the pet, and the human members of the family could also be at risk. Studies show that household levels of these disease-causing bacteria are higher when pets are fed raw foods rather than regular commercial pet foods.
  • Bones present in raw food diets may also harm the pet, potentially resulting in teeth or mouth injuries, choking, and gastrointestinal obstruction or perforation.
  • Commercially available diets marketed as “complete” raw diets can provide the correct balance of nutrients for a dog or cat, but many do not. Home-prepared raw food diets may also not provide complete and balanced nutrition. The effects of feeding a nutritionally imbalanced diet are not always immediately evident, but the consequences can be lifelong for the pet including stunted growth and reproductive problems.

"If you’re considering feeding homemade or commercial raw diets, we recommend that you first consult with a boarded specialist in veterinary nutrition for guidance. While your pet may enjoy eating raw pet food and it may have some benefits, there are several health considerations for your pet and your family that you should know about."

Raw Food Diets

Raw food diets are popular with pet owners but the nutritional benefits are unproven, and most are unaware of the health risks that raw food can pose to pets — and people.
