I'm with Tif, i have also heard of some stories of antlers becoming splintered. apparently, there is a difference between a SHED,(antler found lying in the woods) and a marrow filled fresh antler that was sawed off of a dead deer's head that you just shot... One is more likely to splinter, than the other, but, i can never remember which is which. so being an admitted "worry-wart" about my dog's health, , i skip the antlers..... btw, salix, i'm so EXCITED for you!! the FIRST thing i bought for my dog, and FIRST thing i gave him, was his I.D. tag, already engraved with our address and phone numbers, on a collar, the moment i met him, before he even got into my car, that ID went on. We had pitstops to make on the way home, etc, didn't want my brand new dog to run off on a pee-pee break on the way home... cuz, i'd been warned 8,000 times, that newly rehomed adult dogs are easy to lose in those first few weeks....but, it is way less of risk for a baby dog. I'm assuming the I.D. TAG you mention, is already engraved, etc. I'M SO EXCITED FOR YOU, DO KEEP US POSTED!! NO DETAIL TOO SMALL TO INTEREST US!!! AND WE'D ALL LIKE TONS OF PHOTOS!!
