Overfeeding your dog or cat can lead to obesity.

Nutrition is an important element of your pet’s health. But when it comes to feeding your dog or cat, choosing the best diet can be difficult. Your veterinarian can suggest appropriate options for your pet's specific nutritional needs, but in the meantime, here are answers to some common pet food questions.

What is the best food for my pet?

When it comes to pets, there is no one best or right diet. Like people, different pets have different nutritional needs that can be influenced by a number of factors, including overall health status, medical conditions, activity level and body condition.

Does my pet need a varied diet?

There’s no solid evidence to support that pets are healthier when they eat a variety of foods. However, variety can have some advantages: It can help keep your pet from getting locked into one type of food and can help make it easier to make changes to his diet if necessary. Just be mindful to switch diets slowly, taking several days to gradually introduce a new one. And also watch closely for vomiting, diarrhea or other signs of gastrointestinal upset.

What is the difference between therapeutic and regular diets?

Therapeutic diets are formulated to help manage signs of disease or slow disease progression. Diets formulated to address kidney disease, for example, can slow progression of the disease in pets and improve their quality of life. Therapeutic diets usually contain more defined ingredients, and variation in ingredients is minimized in order to help avoid altering the composition of the food. Ingredients tend to have tighter quality-control standards, and the formulations don’t change unless new scientific information becomes available. Because they’re intended for pets with specific health conditions, these diets are only available through veterinarians and should be used under veterinary supervision.

Is there a danger in feeding my pet the wrong diet?

In a word, yes. Your pet should be fed a diet formulated for his specific stage of life. It would be inappropriate to feed an adult dog a diet designed for growing puppies, for example, because doing so could result in obesity. Likewise, it’d be inappropriate to feed cat food to a dog, or vice versa, because diets are designed specifically to meet the different nutritional requirements of each species.

My pet is overweight. What can I do?

Obesity is a common nutritional problem in dogs and cats. Being overweight can lead to a host of problems, including arthritis, heart disease, diabetes and certain types of cancer. It has even been shown to decrease life expectancy in dogs. When addressing obesity, it helps to feed your pet regular meals every day rather than having food available to him all the time; decrease or eliminate treats; and prevent access to additional foods. Increasing exercise helps, too, assuming your pet is healthy enough to do this. Your veterinarian can tell you if your pet is obese and help you determine how much weight he needs to lose, as well as help you create a plan to address his weight-loss goals.
