Yes, mine do get these treats but very seldom. There are a few reasons too.

Bon absolutely goes nuts for yummy treats like these and gets too excited he can hardly control himself and I know he will woof them down. I have to make him wait till the girls have theirs, and then do some puppy pushups Then he gets his.
Roxey and Huney do like the pigs ears and dried chicken (of course they both chew theirs very well) but don't really care much for the rawhide.

I think in moderation they are fine and if your dog chews them and doesn't swallow them too soon. Angus could never have rawhide...he always tried to swallow large pieces
