Iams® Veterinary Formula™ Maximum-Calorie™ Plus Maximum-Calorie™

Recommended For: Print


Sometimes your dog or cat doesn't eat as well as he should. There are many reasons for his lack of appetite including surgery, illness, and stress. Your pet is most comfortable at home with you, so your veterinarian may suggest that you care for him at home as soon as his condition is stable; and may recommend that you feed him a nutrient-dense diet to assure that he receives the proper nutrition as he recuperates.

How can Maximum Calorie™ formulas help?

Maximum-Calorie™ formulas are especially dense nutritionally. This means they provide your pet with high amounts of nutrients in a small amount of food. This formula is nutritionally balanced to promote wound healing, help promote muscle repair and help replace red blood cells. Its mix of omega fatty acids can help nutritionally manage inflammation in dogs and promote healthy skin and coat in both cats and dogs. Your veterinarian can tell you how much to feed your pet based on his weight and need to gain or maintain.
