My Golden Retriever "puppy" likes to chew on things. She has been very good about staying away from our belongings so far, but she is about to turn 7 months and she is getting bolder. I have been using Booda velvets (the cornstarch bones), and although I believe them to be one of the safest alternatives on the market, (she is also very fond of them) they are expensive and she can destroy one in a day. I have also been using the traditional rawhyde bones, but I've heard that they can do damage to the dog's innards. What do you suggest? Are pig ear and hooves O. K.? Compressed rawhyde? and advice would help. Thank You!
