One toy or two
Color: Raccoon
My dog loves it and it seems durable. The rope 'arms' does pull out but not a big deal. You can put it back or have 2 toys. Would definitely recommend.

A fun and engaging toy that lasts longer than typical plushies
Color: cow, Color: cow
This plush cow toy is designed to be cute, squeaky, and engaging, especially for dogs who need something durable to keep them occupied. I tested it with an energetic chewer who typically destroys plush toys within minutes. Pros: • Adorable design: The cow shape is charming and visually appealing. • Built-in squeaker: Keeps dogs entertained and encourages longer play sessions. • Soft yet reinforced: The fabric is thick, and the stitching is stronger than a standard plush toy. • Good size range: Works for small, medium, and even lightweight large dogs. • Lightweight: Easy for dogs to carry, shake, and toss around. Cons: • Not truly “aggressive chewer” proof—strong chewers will still get through it eventually. • Stuffing can come out once the seams give way, so supervision is recommended.
