I often field questions from dog owners about pet nutrition and supplements. Like other pet owners, you may find yourself faced with many confusing options and conflicting online advice that make you wonder how to supplement your dog’s diet effectively.
The right supplements can help support your dog’s joint health, improve digestive issues, or maintain a shiny coat, but how do you choose the right delivery method? Let’s break down the most common options to help you decide if chews, powders, or oils are best for your pup.
Chews vs. Powdered Dog Supplements
Dog supplement chews are a popular answer to the question of how to supplement your dog’s diet because they’re tasty and easy to administer. Many joint health supplements for older dogs are supplied as chews that contain active ingredients like glucosamine, chondroitin, MSM, green-lipped mussel, or omega-3 fatty acids.
Soft chews are ideal for dogs who refuse pills, and many pet owners find their dogs gobble them up like treats. However, most chews contain filler ingredients that enhance taste, and some dogs may be sensitive to these additives.
Supplement powders offer more flexibility than chews. You can mix powders directly into your dog’s food, which means you can choose the food you think will work best. Many pet parents choose powders for dogs with food sensitivities because powders often contain fewer ingredients and flavorings. However, some picky eaters may refuse their food if they detect a powder mixed in.
Are Oils or Powders Better for Dogs?
Fish oil supplements for dogs are packed with anti-inflammatory benefits, making them a popular choice to address joint pain and skin issues. Fish oil contains omega-3 fatty acids that support immune, coat, and skin health. The downsides are that oils can be messy, go rancid quickly, don’t appeal to all dogs, have limited ingredient possibilities, and can upset some dogs’ stomachs.
So, are oils or powders better? It depends. Oils are ideal for dogs with skin or joint issues because they naturally contain fatty acids; however, they typically don’t contain other ingredients. Powders contain more versatile ingredients and may be better for dogs with digestive health concerns.
What Is the Best Way to Give Supplements to Dogs?
My advice depends on your dog’s overall health needs and taste preferences, and on your budget and daily routine. Here are some things to consider about each delivery method:
- Chews: Convenient and tasty; can be made with a variety of ingredients but often contain additives and flavorings that may bother sensitive dogs.
- Powders: Allow dosing flexibility and often have fewer inactive ingredients; some dogs may dislike the taste.
- Oils: Contain anti-inflammatory fatty acids but can be messy, have a strong smell, and may not appeal to every pet or owner.
Tread carefully if your dog has existing health issues, such as digestive sensitivities or joint problems. Talk to your veterinarian to ensure you choose the right supplement and formulation to avoid worsening your dog’s symptoms.
Comparing Dog Supplement Types
There is no single “best” supplement for all dogs. Consider what your pet truly needs when selecting supplements and formulations. Individual dogs need different types, even if they have similar diets and lifestyles.
Some commonly recommended supplements by need:
- Joint supplements: Glucosamine, chondroitin, MSM, and collagen for senior or active dogs and breeds prone to joint issues.
- Probiotics: Support the microbiome, digestive system, immune system, and overall health.
- Antioxidants: Vitamins C and E and other antioxidants protect cells from free radicals.
- Fish oil: EPA and DHA support skin and coat health and help with inflammation.
- Calming products: Natural ingredients like L-theanine and chamomile can help anxious dogs.
- Essential nutrients: Multivitamins may help overall health, but be cautious with minerals (like calcium) to avoid over-supplementation.
Diet Supplementation Supports Wellness
The first step in deciding how to supplement your dog’s diet is to evaluate your dog’s health needs. Visit your primary care veterinarian for a checkup and discuss supplements that can enhance your dog’s well-being.
When deciding which supplements to buy and in what form, trust your instincts. Ask yourself: Is your dog a picky eater? Do they have a sensitive gastrointestinal system? Do they beg for seafood at the table? Some dogs love chewables, while others do best with powders or oils. Don’t be afraid to try a few formulas to see what works best.
If you’re unsure what your dog needs, ask your vet for guidance. Then, contact the friendly BaxterBoo customer care team with questions or concerns about supplement types, brands, and ingredients that will support your dog’s long-term health and well-being.
