Choosing one of the best supplements for older dogs is a popular way to help alleviate some of the most common senior dog health problems.

But there are SO many different manufacturers, products, claims and hype that it can be very tricky to know how to choose the right, and best, product for your golden oldie.

On this page I only feature products from what I believe to be four of the top manufacturers of pet supplements in the USA.

The Importance of Getting A Correct Diagnosis

Before treating any symptoms or condition in your older dog with supplements or OTC products, please be sure to get a proper veterinary diagnosis first! There are many symptoms which can be indicators of a range of illnesses/conditions, and only your vet will be able to figure out what is at the root of the problem! Once you know what you’re dealing with you’ll be in the best position to choose products which will help get your golden oldie up and running again 🙂

Best Supplements For Older Dogs with Arthritis & Joint Problems

Many older dogs suffer from arthritis, back problems, or issues with their elbows, knees or hips.

Although traditional veterinary medications or even surgery may be needed in some cases, there is also a place for dietary supplements and natural products in alleviating symptoms.

Look for supplements which contain Glucosamine, Chondroitin or Methylsulfonylmethane (aka MSM) or a combination of them.

On average, dogs need around 20mg of Glucosamine per pound of body weight per day.

Supplements will have their own dosage recommendations which you should follow, but this calculation helps you know roughly what you should be aiming for.

Here’s a look at the best supplements for older dogs with bone or joint problems:

Nutramax Dasuquin Soft Chews, Large DogsNutritional supplement containing both Glucosamine and Sodium Chondroitin. Scored tablets.Designed to support joint function and protect cartilage. This product does not contain added MSM


Also available for dogs under 60lbs

Nutramax Cosequin DS Chewables Plus MSMThe #1 Vet recommended dog joint health supplement. Chewable tablet.Contains Glucosamine & Chondroitin plus MSM (as does Dasuquin w/MSM) but in lower dosages.

Best Dog Supplements for Immune System Health

As dogs age their immune system can weaken… chronic disease, poor appetite, limited mobility and more can all affect overall immune function.

Adding certain supplements, especially probiotics which strengthen and support the digestive system, can help your pet’s body handle daily stresses more easily.

Here are some options which I believe are among the best:

VetriScience Laboratories-Probiotic Everyday for Dogs, Digestive Health Supplement-60 Bite Sized Soft Chews

Best Supplements for Dogs with Urinary Problems

Urinary tract problems affect dogs of all ages.

Female dogs are more likely than males to experience urinary infections or hormone-related bladder issues, especially as mature adults.

You can learn more about the loss of bladder control and incontinence in dogs HERE.

Problems can be minimized, or improved, by using certain supplements to maintain healthy UT systems (but a vet visit is essential for new problems as infection requires antibiotic treatment.)

Here are what I think are some of the best supplements for older dogs (or dogs of any age) who have urinary tract issues:

Nutramax Crananidin ChewablesScientifically formulated tablets which contain powerful cranberry extracts.Unique action helps to prevent bacteria from adhering to bladder walls and allows them to be flushed from the body much more effectively.


This isn’t an antibiotic and can’t kill the bacteria, so UTI’s may also require medication, but it can lessen the severity of the infection and help prevent persistent re-infection (common in older dogs).

VetriScience Bladder Strength TabletsTablets containing an advanced combination of ingredients which support good bladder health and function.Increases bladder strength & tone, balances hormone levels and supports healthy kidney function.


Ideal for dogs with post-spay urinary control problems or hormone related incontinence. Can be used long-term for chronic issues.

This holistic blend of 9 herbs is formulated to support healthy urinary tract function.

Gentle, safe and all natural designed to maintain a healthy PH balance in the urine and strengthen immunity to bacteria and infection in the bladder/urethra.

For use as a preventative measure on an on-going basis, not as a remedy for infection or stones.

Best Supplements for Dogs with Skin or Coat Problems

It’s not unusual for an older dog to develop minor skin and coat problems as he ages.

This might happen because of less-efficient circulation, loss of muscle tone, weaker immune system and thinning skin/hair.

Although most of the skin issues you might see are fairly minor, they can cause discomfort or be unsightly. I’m only talking about mild skin irritation, thinning coat, itching and so on.

More serious problems such as red, swollen or irritated skin, lumps/bumps, bald patches or areas which are a constant source of irritation to your dog need to be examined by your vet as soon as possible.

The best supplements for older dogs with skin and/or coat problems will help improve the suppleness and tone of his skin, and keep his coat thick, and shiny.

Here are some that you might want to check out:

VetriScience Derma Strength Dog Skin & Coat CareVegetable flavored chews packed full of essential Omega-3 fatty acids from sources such as salmon oil, safflower oil, flax seeds and linoleic acid PLUS vitamins E (which neutralizes free radicals), B1, B2, C and a range of minerals.Promotes healthy skin tone and texture, full shiny coat and normal shedding patterns.

  1. I have a 12 year old black lab who is losing muscle mass in his hind end. I feed him an adult dog food and I am going to change him to senior food. I feed him Nutri Source. Is there anything else I can add to his diet or an added supplement to help decrease loss of muscle mass?
