Petsmart stopped carrying the GNC brand products. I’m disappointed because Hoshi loved the soft chew probiotics. Honestly they smelled awful 😁. Plus, I trusted the GNC brand. The Authority brand is similar but lesser quality. I’m trying the Only Natural Pet brand because the soft chews are softer and don’t get hard as quickly as the Authority brand.
The Only Natural Pet vitamins contain glucosamine and chondroitin. That might be a problem if you’re already using that joint supplement. They also contain lactobaccillus acidophilus and saccharomyces boulardii probiotics. Again, this could be a problem if you’re already providing these probiotics.
