Tablet vs Soft Chew Forms: Pros and Cons

Tablets in supplements for older dogs provide shelf-stable, exact dosing ideal for large breeds but risk rejection by toothless seniors. Soft chews win for taste-masking and joint-friendly textures, boosting compliance in 80% of cases per Chewy reviews, though they spoil faster in humid climates. Hybrids like PetHonesty balance both, ensuring kidney-safe, anti-inflammatory delivery without digestive upset.
