Our new pup, Sunny, a female 4month old, Boxer/Pointer mix, is now starting to loose her premolars and is officially teething (she already lost her insisors, but we didn't have her for that). When she starts to chew, she starts to hurt and whine. I was wondering if there are any puppy teething toys, like their are human teething toys. I thought about freezing a Kong, but they only sell sizes for large dogs in my town, not 25 lb pups. I am also thinking about freezing those rubber small breed bones. Any ideas???
