2. Limit Signs of Aging and Increase Immune System Effectiveness
"If your dog appears to have some cognitive issues in addition to decreased movement, you’ll want to make sure they’re getting plenty of antioxidants, which can be found in a majority of quality [pet] foods," Dr. Beaver said. Antioxidants like vitamin E and beta-carotene help eliminate free radicals that can damage your pet’s body tissues and cause signs of aging, according to the ASPCA. They can also help increase how effective their immune systems are, much like humans, and keep your pet feeling fit. Look for natural antioxidants like apples, tomatoes, and blueberries on your dog food label.
