Advantage of buying these in packs is that its a lot cheaper than individuals from pet shop, the disadvantage is you can't pick out the nice fat ones. The pack I received contained 5 skinny 'twigs' (NOT VetUK's fault) so won't purchase again.
My dogs loved these, but they didn't last very long. OK as an occasional treat, but too expensive to buy on a regular basis. As a comparison, these would be consumed within an hour or so, whereas rawhide cigar chews would take days.
Not as long lasting as I was hoping but still a good, healthy chew that my dog loves.
