We get ours from various place like PetSmart when they have them and our Holistic pet store. We like to use elk and moose antlers as the deer ones tend to be small and chip rather easily if you get a real narrow one. Regardless you still need to be careful as many bullies do love them but they can and have broken teeth and they can splinter or get sharp edges so be sure to watch your pup with them.
I believe Harlea was 14 or 15 weeks old when we gave her the first one and she is 9 months now and on her 5th one. The others are still good but I jjst need to trim them to cut some points off. Her next one is going to be a piece of moose flat paddle as we have had the best luck with those but you have to get them online and they are sold by the pound and are a bit more expensive
