Dasuquin with MSM and Cosequin DS Plus MSM (both by Nutramax Labs) are excellent products. I prefer these because it is the same company that makes the human product, Cosamin, and one of the few companies that submits its products for outside testing to verify ingredients. The GlycoFlex line of products would also be one to consider. These are my own personal recommendations.

Dasuquin with MSM or Cosequin DS (both by Nutromax Labs) are my personal preferences. Pet Tabs have been around forever and are also a favorite of mine. You can search petco.com for these products or purchase them from your veterinarian.
If he is eating a good quality large breed puppy food, he should not need vitamin supplementation. If you want to give him one, you can't go wrong with Pet Tabs ( https://www.zoetisus.com/products/dogs/pet-tabs.aspx ). A joint supplement, such as Cosequin ( https://www.cosequin.com/ ) or Dasuquin ( https://www.dasuquin.com/en/products/ ), can also be started. Additionally, keep Brandy lean and active.
My personal preference, completed unrelated to Boop by Petco or Petco, would be Cosequin ( http://www.cosequin.com/dogs/ ) or Dasuquin ( http://www.dasuquin.com/en/products/#dog ). Both are made by Nutromax Labs.
Glucosamine and msm would be the most important ingredients, but essential to fatty acids can also be helpful. I recommend brands that perform quality control like Nutramax Vetri-Science, Phycox and Synovi G4. While joint supplements can be very helpful for arthritis and other orthopedic conditions they probably don’t help prevent intervertebral disc disease that causes back problems in dachshunds.
