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 your vet about your dog’s lifestyle. Do not add supplements to your pet’s diet if they are not recommended by your vet. Although offering supplements is done with good intentions, without your 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:

  • Probiotics for an easy and healthy digestion
  • Omega-3 and omega-6 fatty acids for skin, heart, and brain health
  • Vitamin A and beta-carotene to support eye function
  • Glucosamine and chondroitin sulfate for joint health
  • Protein for weight control

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:

  1. Slather the pill with peanut butter or make a pocket in a small piece of cheese or meat and give it to them.
  2. Purchase pill pockets—these are delicious treats with a pocket to place the pills.
  3. Insert the pill directly into your dog’s throat with your hand.
  4. Choose powder or liquid supplements that can be mixed with water or added to your dog’s food.

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!):

  1. Hold your dog’s head from above with your non-dominant hand (for dogs with short muzzles). For dogs with long muzzles, you will hold their jaw between the thumb and middle finger of the non-dominant hand.
  2. Lift your dog’s jaw.
  3. Gently place your dog’s upper lip over their teeth while you open their mouth with the non-dominant hand. If your pet tries to bite you, they will then bite themselves.
  4. Place the thumb of the non-dominant hand on the roof of your dog’s mouth.
  5. Hold the pill between your thumb and forefinger of your dominant hand.
  6. Use the middle finger of your dominant hand to pull the mandible down.
  7. Release the medicine as close to the base of the tongue as possible.
  8. Quickly close your dog’s mouth and massage their neck under the chin to activate the swallowing reflex.

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