We don't give them to Sequoia because she liked to stuff them lengthwise in her mouth and run around the house with them. I was afraid she was going to swallow them whole. I even tried a bigger size and she still managed to get it lengthwise in her mouth. Since she doesn't chew much I didn't feel it was worth the worry.

I am not trying to be an alarmist at all. Like I said there are millions of dogs that have chewed these and not had a problem at all.
