How to Choose the Best Senior Dog Food

As dogs go through different stages of life, their nutritional needs change. What makes a great food for a puppy will not be good for a senior, and so on. When dogs reach their senior years, their metabolisms often slow down. This means that many dogs need fewer calories because more food can be stored as fat. However, senior dogs may need more protein to help with muscle loss. 

Read on to learn how to choose the best senior dog food for your pet.

What Is Senior Dog Food?

Senior dog food is designed to meet the nutritional needs of older dogs. The age of the dog is variable; some large breed dogs transition to senior food at age six or seven years old, while some small dogs might not be ready until they are 11 or 12 years old. Every dog is a little different, so it is always a good idea to talk to your vet about your dog’s changing needs.

When dogs get older, their metabolisms slow, so they need fewer calories. If your dog is gaining weight, it might be a sign of a change in metabolism, and you will want a senior diet with lower calories and lower fat content. 

At the same time, senior dog foods often contain glucosamine, vitamins and minerals, probiotics, and other supplements. If you think that your dog might benefit from any of these supplements, have a talk with your vet. There are many choices available, so you should be able to find exactly what your dog needs.

Does My Dog’s Size Matter?

Generally, the size of your dog does make a difference. Large breed dogs might be ready for senior dog food by the time they are six or seven, whereas small breeds might not need it until later in life. It is important to ask your vet for advice and keep an eye on your dog’s condition. 

Another factor to consider is the size of the kibbles. Many pet food brands have foods specifically for small or large senior dogs. This is important because it can be difficult for small dogs to eat big kibbles, and large and small dogs have different dietary needs across all stages of life, including the senior stage.

Signs That Might Mean Your Dog Is Ready for Senior Dog Food

Besides discussing your dog’s nutritional needs with your vet, there are some signs you can look out for that may indicate that your dog is starting to slow down. Keep in mind the following factors:

Appetite: When dogs age, many of them have a reduced sense of smell and taste. This can make dogs less interested in food. You should make sure that your vet doesn’t find any other causes for this lack of appetite, and then consider switching to a senior diet. You can also mix wet senior food with dry kibbles to make it more enticing.

Activity: As dogs grow older, their activity levels decline. This can lead to weight gain if you keep feeding them the same diet. If you notice your dog gaining weight, it may be time to switch to a senior dog food that has fewer calories and less fat. 

Dental Issues: Senior dogs may develop problems with their teeth and gums. Often changes in dental health are a sign that you should consider senior dog foods. You can also combine canned senior dog food with dry kibbles to make it easier for your dog to chew.

Caned Wet Senior Dog Food Versus Dry Kibbles

You can buy canned wet food or dry kibbles for dogs at every stage of life, including seniors. There are different schools of thought in which is better. Some people think that dry kibble is better because it promotes healthy teeth and gums, and others prefer wet canned food because they claim it has more meat. 

The truth lies somewhere in the middle, and it is a question of what you and your vet think is best for your dog. There are advantages and disadvantages to both, and some people feed a mixture of the two. There are also times when your dog may need one or the other. Take a look at the following:

  • Kibble is easier to store
  • Kibble can be purchased in bulk
  • Kibble is normally less expensive
  • Kibble can help promote dental health
  • Dogs often prefer wet food
  • Wet food has higher moisture content
  • Wet food often has higher protein content

You should consult with your vet, but many people find that if their budgets allow, a combination of the two is middle ground. Sometimes a senior dog needs some wet canned food mixed with the kibble, especially if your dog is a finicky eater or has dental issues. 

Is it Necessary to Buy Premium Senior Dog Food?

Premium dog food is marketed as being better for dogs, and people often think that the price means that it is a better quality food. This isn’t necessarily true across the board. There is little double that feeding your dog a nutritious balanced diet is a good idea, but when you are shopping for dog food, you need to look beyond the premium label. 

To begin with, experts often disagree as to what is the best diet for a dog, which makes sense because dogs come in all shapes and sizes. The needs of a Great Dane may be very different from the needs of a Chihuahua. It is a good idea to talk to your vet to determine what is best for your dog.

Many premium foods have high-quality food that is easily digested. They may also have nutrients and other ingredients that are good for your dog. Normally, premium dog food is made with higher quality protein sources. They shouldn’t contain artificial dyes or preservatives, and there might be extra vitamins, minerals, and other good things such as glucosamine or probiotics. 

Best Senior Dog Foods

The following are some of the best senior dog foods you can buy. Remember that you should consult with your vet about the best diet for your particular dog, and any change in diet should happen gradually. You will want to mix the new food with the old food for a few days during the transition.
