How do you know the best food for your dog?
According to the Association for Pet Obesity Prevention, about 44% of dogs in the U.S. are overweight or obese.
Pet store aisles are lined with dozens of brands of dog food. Many dog owners these days splurge on expensive dog foods, thinking they are buying the best for their dog. But according to many veterinaries, price isn’t a good guideline when it comes to the quality of food.
Dog food ingredients vary, depending on the manufacturer and the brand. Dog food contains protein, which supplies necessary amino acids, fatty acids, vitamins, minerals, and other nutrients. Depending on the manufacturer, the food could contain protein from animal or plant sources. The FDA is responsible for ensuring that pet foods are safe and labeled appropriately. The type of food, whether it is dry or canned, depends on your pet and your preferences.
Many people love to lavish food treats on their dogs: bacon and cheese snacks, pig ears, and an endless amount of table scraps. But all those indulgences come at a hefty price. Too many owners forget to factor treats into a pet’s overall caloric intake. A general recommendation is that treats should not make up more than 15% to 20% of the pet’s total diet.
Adequate water is key to maintain appropriate health for your dog. Water makes up 80% of your dog’s body, and dissolves natural and unnatural substances as well as serves as the root of all biological processes, including digestion.
A nutritious, balanced diet is essential to keeping your dog healthy!
