She's 7 mo-old cocker spaniel. She's done with the teething. She got very strong teeth. I have purchased several toys which she destroyed. Nylabones, Kongs... everything. I don 't know if elk antlers are dangerous for her. I don't think the Extreme Black Kong might work. I purchase a similar product at Old Navy and she destroyed it.
I do play with her using her toys. She also plays alone running with the toy in her teeth.
