I buy the 7" Bully Sticks, and have given them to all my Dogs, however...
When they get short, like less than 1.5", I always take them away from my Guys. I "suspect" that the "shorties" have been swallowed by both Snickers and Becca at times, but, beyond just slowing/interrupting their intake of food, there has been no other consequences. They will digest in a day or so.
BUT !
...
Since I got Ichabod, and he's still rather small (2.3 Lbs), I can turn the 1.5"ers over to him for another .5" of consumption. You know that those sticks usually run about $0.25 inch.
Am I frugal, or, am I frugal.
PS: I assure you I keep a VERY close eye on them (how short they get) and discard them.
