The 10 Best Supplements for Older Dogs

1. Zesty Paws Senior Advanced 11-in-1 Bites – Best Overall

This is a supplement specially created for older and senior dogs that can help restore some of their vitality. With a delicious chicken flavor and very soft texture, you should be able to administer them to the pickiest dogs or those with dental problems.

Zesty Paws Senior Advanced 11-in-1 contains healthy ingredients, such as curcumin, chondroitin, glucosamine, coenzyme Q10, fish oil, vitamin A, B complex, C, and E, methyl sulfonyl methane, cranberry concentrates, and others. This cocktail of active ingredients helps with joint problems, reduces oxidative stress, and strengthens the immune system and intestinal flora.

These supplements can also help the kidney, urinary bladder, liver, heart, and brain to function better.

We think this is the best supplement overall as it covers a wide range of medical conditions and is made with natural ingredients.

2. PetHonesty Hip + Joint Health Soft Chews – Best Value

These supplements are specially created for owners who want their dogs to have healthy bones and joints and for dogs with joint problems to improve mobility and restore their zest for life. PetHonesty Hip + Joint Health contains glucosamine, chondroitin sulfate, MSM, omega-3, vitamin E, eggshell membrane (as a source of collagen), powdered cellulose, sweet potato, tomatoes, and others. Glucosamine helps stimulate new cartilage growth and protects the cartilage in the joint, while chondroitin sulfate helps keep the joint lubricated, ensures shock absorption, and supports the tissues lining the joint.

It has chicken flavoring and is suitable for all breeds of dogs of all ages. It does not contain corn, soy, or wheat and is non-GMO, which means it is produced without genetic engineering.

These ingredients have an antioxidant and anti-inflammatory role and help the locomotor system function properly by reducing inflammation and stiff joints associated with daily exercises. For this reason, this is the best supplement for older dogs for the money.

3. Nutramax Cosequin Maximum Strength – Premium Choice

Dogs that are less active, show no interest in daily activities, have difficulty getting up or lying down, have a stiff gait, and have joint pain can show improvements if they are given these supplements. Nutramax Cosequin Hip & Joint Maximum Strength Plus MSM contains only three ingredients—glucosamine hydrochloride, sodium chondroitin sulfate, and methylsulfonylmethane (MSM). Glucosamine has been shown to be safe for long-term use, so a joint supplement containing glucosamine may be useful as an early intervention for dogs susceptible to osteoarthritis, such as large and giant breed dogs.

Chondroitin inhibits cartilage degradation and promotes the production of cartilage components. Combined with glucosamine, they can reduce inflammation and help prevent the destruction of joint cartilage.

Thanks to the active ingredients, these joint supplements for dogs can help maintain mobility, reduce pain and inflammation, encourage the growth of new cartilage, and prevent cartilage degradation.

All in all, it helps to reduce joint inflammation and supports cartilage health.

4. Purina Pro Plan Veterinary Diets FortiFlora Powder

The good bacteria that populate the intestinal flora essentially contribute to the health of the body’s immune system. Probiotics are made up of good bacteria and yeast and have many benefits for dogs, including reducing excess gas, helping with healthy digestion, supporting the immune system, helping reduce bad breath, preventing digestive problems and vomiting, improving your dog’s general well-being, and many others.

Purina Pro Plan Veterinary Diets FortiFlora Powder Digestive Supplement contains live microorganisms and antioxidants and does exactly these things, especially helping to remedy gastrointestinal problems such as diarrhea. It is a good-tasting powder supplement for dogs that can be added to their regular food. It can be used on any breed of any age, including senior dogs.

5. PetHonesty Digestive Probiotics Soft Chews

If the intestine is affected, the intestinal flora may die, which in turn causes the large intestine to stop working as usual in dogs. Affected dogs often suffer from diarrhea and nausea. They also lose their appetite and gradually lose weight.

If your dog struggles with certain gastrointestinal problems such as bloating, constipation, diarrhea, and gas, then PetHonesty Digestive Probiotics could benefit them because it helps to repopulate the beneficial bacteria in the intestinal tract. It also helps to maintain a healthy immune system.

These supplements contain 1 billion colony-forming units (CFU) of probiotics per serving and pumpkin. They are duck flavored and do not contain soy, wheat, corn, or harsh preservatives, and are non-GMO.

Omega 3 fatty acids play an important role in protecting the cardiovascular system of dogs. The omega-3 fatty acids in salmon oil reduce cholesterol and triglyceride levels and the clogging of the blood vessels. Fatty acids also help with good blood circulation and ensure better tissue oxygenation.

Omega-3 and omega-6 fatty acids help reduce inflammation and joint pain, restore joint mobility, and slow down the degenerative processes due to aging. Zesty Paws Wild Alaskan Salmon Oil comes in a liquid form, which is easy to administer—simply add as many pumps as are necessary for your dog’s weight to their food. It is suited for all dogs, including seniors.

Buyer’s Guide: Choosing the Best Supplement for Older Dogs

What to Consider When Selecting the Best Senior Dog Supplements

As your dog gets older, they go through a multitude of changes. Therefore, in order to ensure your pet’s well-being, it is essential to adapt their diet according to their nutritional needs.

Along with normal changes such as a slow metabolism or less active immune system, senior dogs also have other health problems such as osteoarthritis, visual impairment, skin problems, or kidney problems. These aspects make your dog’s diet occupy a vital place in their care, but supplements should not be neglected either.

Talk to a vet about your dog’s lifestyle. Do not add supplements to your pet’s diet if they are not recommended by the vet. Although offering supplements is done with good intentions, without the vet’s recommendation, they can make your dog sick. For example, diabetic dogs should avoid supplements that contain sugar.

When you decide to give your dog supplements, look for those that are made from natural ingredients and don’t contain sugar and fillers.

If your dog suffers from a specific condition—for example, if they have joint problems—focus on supplements designed specifically for joint health. If you just want your beloved four-legged friend to have an energy boost and an increased appetite, then choose supplements that contain vitamins and minerals. For skin and coat problems, fish oil supplements are the most recommended.

What Makes a Good Product for Senior Dogs?

Senior dogs need certain nutrients to help them with the health problems that come with aging. These nutrients include:

A good product will contain all of the above and will not contain sugar, corn syrup, or filler ingredients. Sugar can contribute to weight gain and lead to obesity, which in turn can lead to diabetes. Also, too much sugar in your dog’s diet will lead to digestive problems (soft stools or diarrhea).

If your dog has a specific problem (e.g., joint problems), you can choose supplements that contain high concentrations of the key ingredients, as those can help improve their condition.

What Should I Do If My Dog Refuses to Take Supplements?

Usually, supplements have a pleasant smell and an attractive taste for dogs. However, sometimes dogs do not like the smell and refuse to eat them. If your dog is among the picky eaters and doesn’t want to take supplements, you have a few options:

Giving your dog pills can be a real challenge, but don’t get overwhelmed because once you learn how to do it, it’s fairly easy. Here’s what you need to do (be careful not to get bitten!):

If none of these methods work, try other brands of supplements until you find one that your dog will tolerate.
