I have not had any luck with antlers. I gave one to my parents dogs and all four of them ignored it after the first sniff. I'd love to hear how your pup responds to it though. Maybe I will try it on my border one of these days.
Thx for the response! He loves the thing so far. A life saver when I just need to leave the room for a sec or go to work for 5 hours. Keeps him busy enough altleast for him not to care when I leave, initially that is. Haha not sure how he reacts once he realizes I ain't comin back right away...seems pretty safr so far. Ii looks as though it will last a long time, I would certainly suggests trying again.
