Another appreciated the ease of use and taste for their pet, stating that “He loves it and takes it in the syringe by squirting it in the side of his mouth (kind of messy), licking it up alone or on top of his food. It does seem to run out quickly, but it’s a good price and at least he’s actually taking it so we’ll stick with it.”

What our vets think

What to look for in the best dog supplements

On the hunt for the best supplements for your pet? Here are a few things to watch for as you search. 

  • Quality of formulation. You’ll want to pick a product that’s free from fillers, colors, parabens, preservatives, and artificial flavors. These can all harm your pet’s health over time and are generally best to steer clear from. You’ll also want to keep an eye out for assurances, like human-grade formulation, non-GMO formulas, and organic ingredients – these are better options. 
  • Origin. While there are plenty of quality international products, products made in the USA generally have higher standards and stricter regulations that are designed to protect your pet’s health. When you’re shopping for consumables, it’s best to check for this label or promise. 
  • Reviews. Pet parents will be incredibly honest about their pet’s experiences. Check for reviews to get a glimpse of what you and your pet might experience if you make the purchase. 
  • Ethical practices. Sustainability is a big deal — and so are production ethics. It’s best to shop responsibly and support brands that are transparent about their sourcing and formulation practices. 
  • Price. When it comes to supplements, going for the cheapest product may not be the best idea — but the most expensive isn’t always perfect either. Finding something in the middle is usually a safe bet while not breaking the bank in the long term.

What supplements should I give my dog to stay healthy?

It’s best to consult your veterinarian before putting your dog on any supplements. However, it’s generally best to make sure your dog’s diet is rich in the following:: 

  • Amino acids (arginine, histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, valine)
  • Glucosamine
  • Chondroitin
  • Enzymes (lipase, amylase, protease, papain, bromelain, cellulase)

You can also check the ingredients for included minerals (like calcium, phosphorus, sodium, chloride, potassium, magnesium, zinc, copper, manganese, selenium, iodine), probiotics, omegas, coenzyme Q10, and antioxidant content.

Frequently asked questions

Are dog supplements worth it? 

Yes, dog supplements can be a helpful tool to consider as you work to proactively protect your dog’s health. They can be especially useful if you are working to address a deficiency or condition in your dog. 

What vitamins should dogs not take? 

Your veterinarian is the best source of information regarding what your pet should and should not take. However, it’s best to steer clear of iron and vitamins A and D that haven’t been optimized for your pet, as they can lead to stomach upset. 

Should dogs take fish oil? 

Fish oil is a helpful supplement for many dogs, working to proactively support their heart, skin, and coat health. It can also be a helpful supplement to consider if your pet is experiencing any sort of inflammation-related joint pain. 

Can dog supplements really work? 

Dog supplements generally work if they are manufactured well and use healthy, transparent ingredients. Pet parents who are concerned about the efficacy of their supplements can look for clinical trial assertions on the bottle or the insert. 

Should I give my dog supplements every day? 

Your dog may not need supplements if they are eating a complete dog food,  as they are likely getting what they need from their food.
