Background

Encoded by the ob (obese) gene, Leptin is an adipose-derived cytokine that suppresses appetite and increases thermogenesis. The absence of leptin (or its receptor) leads to uncontrolled food intake and resulting obesity. Leptin exerts its anorectic effect via signaling through a hypothalamic receptor termed OB-R. Leptin has been shown to reduce body weight, food consumption, and plasma glucose levels in various in vivo models. Recombinant Human Leptin is a 16.0kDa protein containing 146 amino acid residues.

Adorable, Durable, and Dog-Approved!
Size: Medium, Style: Sour Pooch, Size: Medium, Style: Sour Pooch
My dog loves the Sour Pooch dog toy—so much that it’s quickly become one of his favorites! What really surprised me is how durable it is. He’s usually quick to tear toys apart, but this one has held up incredibly well, making it one of the few survivors in his toy box. The toy is super cute, lightweight, and just an all-around fun addition to his collection. It’s been a joy watching him carry it around and play with it daily. I’d definitely purchase again and highly recommend it to other dog lovers looking for a toy that can handle a bit of rough love.

Squeaky and colorful
Size: Small, Style: Skit-Tails
Cute toy. Lots of squeaks. Probably best for a mid sized dog mouth— a chihuahua or Pomeranian might find it a little thick to manage.

“Candy” dog toy
Size: Small, Style: Mutts & Mongrels
Great toy! I like the toy because it’s durable & it has no appendages to for the dogs to chew off. It will be destroyed at some point but I won’t have to start picking up stuffing for a long time.
