Product title: Free Raised Pet Products, 5-6 inch Standard Bully Stick Twin Pack, 20 Bully Sticks'
Product description: You are purchasing (20) 5-6" Standard bully sticks. You will actually be receiving (10) 2-Packs, for a total of (20 sticks). These are Free Range Eco Naturals Moo! brand. (Many people choose our 5-6" standard bully sticks for smaller breeds of dogs. Although larger dogs like them too, many larger dogs will eat them rather quickly. As such they make a great snack for larger dogs, but are the perfect size for a smaller dog.) What do the terms Standard, Select, Supreme, Monster, and Beyond Monster mean? The terms have to do with how the bully sticks are sorted. All the bully sticks are sorted by weight, so you get what you pay for. Most companies sort by looks only which can sometimes be deceiving because a lot of times a bully stick can look very big, but can be very light in weight. So even though it looks big, it won't last as long because it is light and not very dense. So the size order from lightest to heaviest goes Standard, Select, Supreme, Monster, and Beyond Monster which are the heaviest. What makes Free Range Eco Naturals Moo! brand bully sticks different than the bully sticks I purchase anywhere else? Free Range Eco Naturals Moo! brand bully sticks are from Argentina Pampus Angus Cattle. Pampus Angus Beef is the story of a healthy lifestyle.
