Bully sticks (aka pizzle sticks) are actually bullepees hond gevaarlijk bull penises (most dog owners probably don't like to think about this, but since their dogs love it, perhaps they pretend to forget about what they're actually made of). The penis is severed from the bull, then stretched, bleach - cleaned, dried and hardened for consumptions; the brands made for puppies vary in sizes & shapes; they can be twisted into knots, braids or rings; and the total size of a beef stick spans about 40" to 50" long. The preferred method for producing these type of dog-chews is by natural means (non-synthetic additives) so they are palatable to puppies.
Beef sticks can be relished for a longer time than a number of other dog-chews. They are durable and can literally last for weeks when chewed by smaller breed of dogs (or could be ingested by larger breeds of canine in several hours). That's pretty remarkable 'hang time' when compared to a number of other supposedly 'long-lasting' dog-chews (that can normally be consumed in just minutes). Large chew sticks are considered to be the most solid treat for canines weighing between twelve to fifteen pounds. Overall, these delectable, durable treats are readily digestible and can handle the natural chewing power of any dog, The friction against the teeth caused by the constant biting of the beef treat, also eliminates tartar - encouraging healthy gums and teeth. Most beef treats are procured from free ranging, grass-fed, naturally reared livestock. Normally ranging from small, medium to large, these dog-chews are usually packed inside a resealable bag - specially made to lock in freshness.
There are potential risks with pizzle sticks though. If a bully stick is too rich for a puppy with a weak constitution, it may loosen his stool. Also, beef sticks that are manufactured under poor sanitary conditions (oftentimes, outside of America) run the risk of being contaminated with salmonella; contact with this bacterial agent, however brief, can lead to infection or becoming a carrier; cross-contamination with toddlers or the elderly can prove fatal (given their underdeveloped immune system).
