Clinical studies show that supplementing with glucosamine sulfate may stimulate joint repair. FlexAble Glucosamine Sulfate is fully reacted and is made up of a combination of glucose, glutamine and sulphur. It is generally believed that the sulphur component makes it more useful for joint problems.

This formula is sodium free, for those who wish to reduce their sodium intake or people with hypertension.

One common question: Can persons allergic to sulfa drugs or sulfite take glucosamine? Michael Murray, ND responds: "When people say they are allergic to sulphur, what they really mean is they are allergic to the so-called sulfa drugs or sulfite-containing food additives. It is impossible to be allergic to sulphur because sulphur is an essential mineral. The sulfate form of sulphur is present in relatively high concentrations in human blood. In short, glucosamine sulfate is extremely well-tolerated, and no allergic reactions have been reported."

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.

Not worth it
Color: cow
My husky puppy ate this thing in less than an hour. The rope arms come out pretty easily. Waste of money unless you have a tiny dog that doesn't chew much. Defeats the purpose of having rope to play tug of war when it's so small and easily torn. The chewability is null with this thing.

Doggy loves it
Color: cow
This cow toy is awesome. It is made really well and will stand up to my tough chewer for a bit. I love that the arms are ropes for easier chewing and tugging play, which is my bernedoodle's favorite. It has a squeaker too of course. It is a super cute toy to add to your dog's collection!
