How Heavy Should My Dog Be? Tips for Calculating Dog Weight

A healthy dog weight refers to your dog’s ideal body weight, or the weight range for an adult dog based on its breed and metabolism. However, ideal weight is difficult to determine because individual dog breeds differ in shape, size, and build; for example, Chihuahuas are much smaller than Great Danes.

Many breed weight charts list the average weight range for different breeds, but they overlook several essential factors and provide only part of an accurate depiction of a dog’s healthy weight. Average weight charts overlook dog breeds prone to weight gain, such as small dogs like American cocker spaniels and Cavalier King Charles spaniels, beagles, and dachshunds, as well as Labrador retrievers, collies, and Shetland sheepdogs.

Many veterinarians prefer the body condition score (BCS) system over dog weight charts to determine a dog’s ideal weight. The body condition system uses the dog owner’s senses of sight and touch to calculate a healthy weight range for their pet.

Dog owners should determine if their pet is within a healthy weight range for several reasons, including:

1. 1. A healthy weight can help extend your dog’s lifespan. Knowing your dog’s ideal weight can contribute to helping them live long and healthy lives.
2. 2. Overweight dogs can experience long-term health issues. Dogs that exceed their ideal body weight face numerous health problems. Obesity contributes to heart and liver disease, hypertension, bone and joint damage, and an overall decrease in the quality of a dog’s health and life.
3. 3. Underweight dogs may have underlying health conditions. It’s just as important to know if your dog is below its ideal body weight. Sudden or inexplicable weight loss may signify an underlying medical condition, such as cancer, parasites, or Addison’s disease. It may also mean your pet needs more calories and proper nutrition from different dog food.

Dog weight charts can be a helpful general guide, but they have limitations. Dog weight charts:

• Ignore genetic factors: Average weight charts omit genetic health factors that contribute to weight gain. Boxers, German shepherds, and small breed dogs like American Staffordshire terriers, Boston terriers, and Yorkshire terriers are all prone to Cushing’s disease, which affects how your dog’s body regulates weight. Medium-sized dogs and large breed dogs like miniature schnauzers, Irish setters, pitbull terriers, and Doberman pinschers are susceptible to hypothyroidism, which causes weight gain due to an underactive thyroid gland.
• Only account for purebred dogs: Weight charts only include purebred dogs, overlooking mixed breed dogs like Maltipoos (Maltese and poodle), pitskys (American pitbull terrier and Alaskan/Siberian husky), or bernedoodles (Bernese mountain dog and poodle).
• Overlook energy levels: Dog weight charts may suggest the adult weight of basset hounds, Australian cattle dogs, German pinschers, and bulldogs should all be approximately fifty pounds. However, each of these breeds differs in energy levels and build.

The body condition score (BCS) helps you calculate your dog’s ideal healthy weight. Here are some tips for determining your dog’s weight using the BCS system:

1. 1. Observe your dog. Examine your dog’s body, looking at the rib cage, abdomen, and waistline in profile and while standing above your dog. Use your hands to feel your dog’s ribs. Look for an “abdominal tuck”—a curve in the belly behind the ribs—and an inward curve in the waistline.
2. 2. Note their condition. Dogs within their ideal healthy weight range have palpable ribs and possess both a subtle abdominal tuck and waistline curve. Overweight dogs have layers of fat over their ribs and lack the abdominal tuck and curve at the waist. Underweight dogs have visible ribs and vertebrae and a deeper curve at the waist and abdomen.
3. 3. Grade the observation. The BCS method uses a nine-point system to determine the dog’s body condition score. Underweight dogs receive grades between one and three, while overweight dogs earn grades of six through nine (obese dogs receive a nine). If a dog’s body meets the criteria for ideal weight, it’s graded with a four or five.
4. 4. Talk with your veterinarian about the score. Use the BCS to determine if your dog is within a healthy weight range. Discuss your calculation with your vet, and ask them to assess your dog’s body condition score to determine if you need to adjust your dog’s diet.
