Senior dog supplements come in all shapes, sizes and formulas. They also target a wide range of health issues or needs.

Not every older dog needs a nutritional supplement or extra vitamins/nutrients.

If your golden oldie is active, happy, in good general health and eating a premium dog food (or a well-balanced homemade diet) then chances are he’s getting everything he needs.

But, if your old dog suffers from any minor, chronic (or even serious) health conditions, dog supplements could:

  • Relieve some symptoms
  • Improve overall immune health (which helps his body handle stress/illness)
  • Provide a higher level of certain beneficial nutrients

See the specific supplements I would recommend for a variety of conditions here….

Best Supplements for Older Dogs.

Although studies have been done on the effects of certain supplements and vitamins for dogs, generally these have been fairly small and over a short time period.

There are no studies that have looked at the long-term effects that I am aware of.

This is one of the reasons that I personally wouldn’t choose to give supplements or added vitamins to a puppy or younger dog, if I intended for them to take them indefinitely.

Choosing Dog Vitamins & Supplements

As a human being, who isn’t as young as she once was, I have a working knowledge of nutritional supplements, vitamins and minerals. And yes, I do take some myself.

Supplements for older dogs work in generally the same way that supplements for older people do… but of course the dosage and available products are not the same.

Also similar, is that supplements are not regulated in the same way medications are and are not subject to standardized testing or trials.

A manufacturer can basically stick a label on any product, making almost any claim they want to, and it is difficult for you (or I) to figure out how true those claims are. Sometimes it’s impossible.

This obviously makes finding the best products a bit of a minefield for the average dog owner, and one of the reasons I decided to create this page.

In my experience, the best way to choose supplements for dogs is the same way I choose supplements for myself… through research of the manufacturer and their practices.

Whenever possible look for senior dog supplements which are manufactured by responsible, credible companies who test their products extensively and are endorsed by professionals in the veterinary field.

And who also meet any FDA or other requirements… such as the Good Manufacturing Practices set out for dietary supplements.

Independent testing of supplements manufactured for the pet market have shown that they tend to have a lower quality (and often less of the active/important ingredients) than those designed for the human market.

This emphasizes the importance of buying from reputable and well regulated manufacturers.

Here’s a look at the manufacturers I believe offer dog nutritional supplements which fit these criteria:

Nutramax Laboratories

Nutramax produces supplements (for dogs, cats and people) in a state-of-the-art facility and in compliance with the FDA’s Good Manufacturing Practices for dietary supplements.

Rigorous quality control, quality assurance, ongoing research and development and staff training all contribute to producing top of the line supplements which live up to their labeling and are both safe and effective.

Dog Health Conditions & Dietary Supplementation

So, now let’s take a look at the types of conditions or situations where you may want to consider giving senior dog supplements to your golden oldie.

There are specific health problems which affect senior dogs (and younger ones too) and which can often benefit from supplements, vitamins or herbal products.

These might be given in addition to conventional medications or treatments BUT it’s possible for any supplement/vitamin to interact (negatively) with other medications or products your dog is taking. This could be dangerous….

Consult your vet BEFORE giving your dog any supplement/vitamin

It’s hugely important not to give your dog anything (even a ‘natural’ remedy) without consulting your veterinarian first if he/she has any underlying health problems or is taking any medications or other supplements etc.

Even if your dog is totally healthy, it’s always a good idea to check with your vet before starting giving supplements, vitamins, herbal or holistic remedies, or other similar products.

Some of the most common health issues in older dogs which may benefit from dietary supplements include:

  • Arthritis and joint problems
  • Poor immune system function
  • Urinary problems (including incontinence)
  • Skin and coat issues
  • Heart, liver or kidney problems
  • Digestive issues
  • Brain or neurological conditions
  • Weight problems (either weight loss or weight gain)

No matter how wonderful the claims for any medication, supplement, vitamin or herbal/natural/holistic remedy – it’s worth remembering that they are not ‘magic bullets’.

In many cases mainstream treatments, dietary supplements or herbal products (or a combination of several) can have a positive impact on either a specific health condition or your dog’s general health.

But no supplement can cure serious illnesses such as canine parvovirus, cancer, organ failure, hip or elbow dysplasia and so on.

It’s also a good idea to take a whole-body approach to treating any type of illness or chronic complaint.

This includes making sure your senior pet has a nutritious, well-balanced diet, an appropriate amount of exercise (see this page for tips on exercise for senior dogs… Exercising Older Dogs) and regular veterinary care.

  1. My uncle has a 10-year old senior dog. It’s his best pet ever and it’s his only companion when his wife died 5 years ago. He wants to give his dog some supplements so it will live longer. I will be discussing this information with him once he visits us again.

  2. Thanks for the suggestion to talk to a vet about supplements to determine if my dog likely has a particular deficiency. My husband and I have noticed our dog seems to be having skin and coat issues, even after eating regular doses of food. Hopefully we can figure out our dog’s dietary needs and find great supplements if necessary.

  3. I am glad I stumbled upon this article because it helped me narrow down what I need to be giving my dog and watch out where they are manufactured and come from. My vet also said some vitamins can actually be worse for your dog… what the heck!! When I was talking to her she recommended I try to give my dog Balanced Breed multivitamins. They are made with all-natural, limited ingredients and sourced in the states. After trying the all-natural Balanced Breed ones, I can proudly say my dog definitely is more energetic and happy as I love to see him living his life even at the age of 11
