Buyer’s Guide: Choosing the Best Dog Foods for Jack Russells
Though all dogs generally have the same basic nutritional needs, your beloved Jack Russell needs more energy due to their faster metabolism. To give your Jack Russell the best possible diet, choose a brand that balances healthy proteins, fats, and carbohydrates. In general, your dog will need a minimum of 18% protein and 5% healthy fats in their diet to meet basic nutritional needs.
It’s important to determine if the protein in the food comes from high-quality animal sources. Look for ingredients such as red meats, chicken, or fish. You’ll also want to check that the brand uses healthy animal fats like chicken fat or salmon oil paired with a good balance of omega fatty acids.
Food with whole grains and vegetables can provide your dog with rich sources of fiber and other essential nutrients.
Dietary Considerations for Jack Russells
Maintaining a healthy body weight is essential for your Jack Russell. The breed is more at risk for obesity because of its size, and obesity can lead to musculoskeletal problems.
You also need to keep in mind that a majority of Jack Russells are prone to skin allergies and food sensitivities. Your dog will need a carefully monitored diet to prevent triggering any food allergens that may be present. If your dog often has skin problems, they may be related to a food insensitivity. It is always wise to check with a veterinarian prior to any major dietary changes.
