1) Define the objective

• Soothe (after a walk, in the evening): favour medium textures and stuffable toys .
• Keep occupied (alone 10–20 min supervised): sturdy toys, complex shapes.
• Maintaining the mouth: textured toys that gently "brush".

2) Hardness & safety

• Simple rule: if a nail leaves no mark → too hard = dental risk.
• Avoid brittle or abrasive objects. Opt for materials designed for dogs.
• Always monitor the first sessions; replace if cracked.

3) Size & shape

• Choose a size that the dog cannot swallow and that fills its mouth well.
• Shapes: textured stick, ergonomic bone, stuffing toy (capsule/ball), ring.
• Puppies: lightweight XS/S sizes; seniors: easy to grip, medium density.

4) Common materials

• Technical rubber : durable, washable, sometimes stuffable.
• Textured nylon : available in different hardnesses; monitor for wear.
• Reinforced fabric/rope : for soft play and puppies (supervision).

5) Duration & frequency

• 5–15 min, 1–2 times/day depending on the dog. Short and regular sessions are best.
• Remove the toy if the dog becomes overly aggressive or excessively excited.

6) Maintenance & hygiene

• Wash in hot soapy water; some are dishwasher safe (check the instructions).
• Replace as soon as there are cracks or large pieces missing.

7) Quick checklist

• Clear objective (calm/occupy/dental)
• Suitable hardness (nail test)
• Safe size (not swallowable)
• Shape adapted to chewing style
• Safe & washable material
• Monitoring and replacement if worn
