The Ferplast Smile is a fun ring-shaped dog toy, specifically designed for dental hygiene. This EXTRA SMALL model is ideal for very small dogs. Made from non-toxic and safe material, it won't harm your four-legged friend's gums and is very durable, perfect even for the most avid chewers. Its irregular surface stimulates chewing action, helping to keep teeth clean and gently massage the gums, while exercising the mouth muscles. The Ferplast SMILE toy line is available in different shapes (bone or ring), colours, and sizes: EXTRA SMALL (suitable for very small dogs), SMALL (suitable for small dogs), MEDIUM (ideal for medium-sized dogs), and LARGE (for large dogs).
