The weight of a dog would depend on the breed and the sex. There are many factors for weight loss or obesity in dogs. See the below table for the Approximate ideal weight for each dog breed.
Keeping your dog in an ideal weight would extend your dog’s life, and also they would live happier. If you believe your dog is too thin, or overweight, please consult your veterinarian. The below table would suggest the ideal weight for each breed. If you have a mixed breed, there is no clear reference for the weight, and your vet will check your dog with the body condition system chart.
