If you're wondering how to choose the best dog supplements or which pet supplement company you can trust, you're asking an important question. With hundreds of brands available online, it can be difficult to separate products backed by science and quality standards from those driven primarily by marketing.
As a veterinarian, I encourage dog owners to look beyond attractive packaging and bold claims. A trustworthy supplement company should be transparent about how its products are formulated, manufactured, tested, and supported. Here are the qualities I believe every dog owner should look for before making a decision.
1. Veterinary Expertise Matters
One of the first questions I would ask is simple:
"Who developed this product?"
A supplement created with veterinary input is far more likely to focus on real canine health needs rather than the latest marketing trend.
Veterinary professionals understand how nutrition, ingredients, and overall health work together. They also recognize the importance of safety, realistic expectations, and knowing when a supplement can help support health and when a dog needs veterinary care instead.
At Dr. Ferg's, every product is developed with veterinary oversight and backed by a customer support team of trained veterinary nurses who help answer owners' questions every day, with anything beyond routine guidance escalated to Dr. Feargus McConnell, our veterinarian, for his input.
2. Look for Science, Not Hype
The pet industry introduces new "miracle ingredients" every year.
While some become valuable additions to canine nutrition, others gain popularity long before meaningful research exists.
Trustworthy companies don't formulate products based on trends alone. They evaluate the available evidence and choose ingredients that have been studied for the health concern they're intended to support.
Just as importantly, they include those ingredients at levels that align with the available scientific research whenever appropriate.
Science should guide formulation decisions, not marketing.
3. Manufacturing Standards Tell You a Lot
Where and how a supplement is manufactured matters.
Companies that are proud of their manufacturing standards are usually happy to tell you where their products are made and the quality systems they follow.
For example, at Dr. Ferg's, our supplements are:
- Manufactured in the USA with U.S. and globally sourced ingredients
- Produced in an FDA-registered facility
- Manufactured under current Good Manufacturing Practice (cGMP) conditions
- Scientifically formulated
- Third-party lab tested
These standards help ensure consistency, quality, and accountability throughout the manufacturing process.
4. Ingredient Quality Should Never Be an Afterthought
A great formula starts with great ingredients.
That means selecting ingredients based on quality, purity, and scientific evidence rather than simply choosing the lowest-cost option.
Some ingredients also have unique stories.
For example, our Green Lipped Mussel is sourced from the pristine coastal waters of New Zealand, where ideal environmental conditions help produce one of the world's most respected natural joint support ingredients.
Combining carefully sourced ingredients with rigorous manufacturing standards helps create products owners can feel confident using every day.
5. Transparency Builds Confidence
A trustworthy company doesn't hide behind vague marketing language.
Instead, it clearly explains:
- Where products are made
- How they're tested
- Why ingredients were selected
- Who formulated them
- What standards guide production
Transparency allows dog owners to make informed decisions rather than relying solely on advertising claims.
If you can't easily find this information, it's worth asking why.
6. Clean Labels Matter
Many owners today are paying closer attention to ingredient lists than ever before.
A trustworthy supplement company should clearly explain both what is included and what is intentionally left out.
At Dr. Ferg's, our formulas contain:
- No artificial colors
- No artificial flavors
- No artificial preservatives
- No corn
- No soy
- No wheat
- No GMOs
Our focus is on thoughtfully selected ingredients that serve a purpose, without unnecessary additives.
7. Customer Support Should Be Educational
One of the biggest differences between companies is what happens after you make a purchase.
Can you speak with someone who understands canine health?
Can they answer questions about ingredients, feeding recommendations, or common concerns?
Or are you simply speaking with a general customer service representative reading from a script?
We believe dog owners deserve knowledgeable guidance from trained veterinary professionals who can help explain products, answer questions, and encourage veterinary care whenever it's appropriate.
8. Responsible Companies Think Beyond Their Products
Today's consumers increasingly want to support businesses that make responsible choices.
For us, that includes partnering with rePurpose Global and making a financial commitment to help remove ocean-bound plastic from the environment.
While sustainability doesn't determine whether a supplement is effective, it does reflect the values of the company behind it.
We believe caring for dogs also means caring for the world they live in.
Questions Every Dog Owner Should Ask
Before choosing any supplement, consider asking these questions:
- Is the product scientifically formulated?
- Who developed it?
- Is it manufactured in the USA?
- Is it produced in an FDA-registered facility?
- Is it manufactured under cGMP conditions?
- Is it independently third-party tested?
- What ingredients are used?
- Are the ingredients sourced responsibly?
- Is knowledgeable customer support available?
Companies that prioritize quality are usually proud to answer these questions.
The Dr. Ferg's Philosophy
At Dr. Ferg's, we've built our company around a simple belief: trust is earned through transparency, science, and consistently high standards.
That means developing products with veterinary oversight, using carefully selected ingredients, manufacturing in the USA under cGMP conditions, producing every supplement in an FDA-registered facility, independently third-party testing every batch, and providing customer support through trained veterinary professionals.
As a veterinarian, I know dog owners have many choices when it comes to supplements. My hope is that every owner, whether they choose our products or not, feels empowered to ask better questions, expect higher standards, and make informed decisions for the dogs they love.
