Frequently asked questions
What is the benefit of chicken meal in dog food?
Chicken meal is fresh chicken that has been rendered, a process that removes water and fat. This results in a highly concentrated, protein-dense ingredient, ensuring your dog gets more animal protein in every bite to support muscle maintenance.
Is this food appropriate for a senior large-breed dog?
Yes, this Adult 7+ formula is well-suited for senior dogs of most breeds, including large ones. The nutrition is balanced for aging dogs in general, and the large 33 lb. bag is an economical and convenient choice for owners of bigger dogs.
Why should I choose a "senior" formula for my older dog?
As dogs age, their metabolism slows and their nutritional needs change. Senior formulas like this one are typically designed with controlled mineral levels to support kidney and heart health, plus specific antioxidants and nutrients to promote a healthy immune system and joint mobility.
Are grains like barley and rice healthy for my senior dog?
For most dogs, wholesome grains like barley and rice are excellent sources of fiber, carbohydrates for energy, and essential nutrients. Unless your dog has a specific grain allergy or sensitivity, these ingredients are a healthy part of a balanced diet.
Is Hill's Science Diet recommended by veterinarians?
Hill's Science Diet is one of the most well-known brands in the veterinary community. The company invests heavily in nutritional research and testing, and its products are frequently recommended by veterinarians for various life stages and health needs.
How long will a 33 lb bag of this food last?
It depends entirely on the size of your dog. For a medium-sized dog weighing around 40-50 lbs, this bag might last approximately 6-8 weeks. For a larger 80lb dog, it could last closer to one month. Always check the feeding guide for accurate portioning.
