I NEVER give any of mine rawhide chews.
Many years ago (b4 Cockers) I had a GSD, I bought him a huge rawhide chew, he spent ages gnawing & thoroughly enjoying himself, with it.
Until, that is, he too started choking, really badly, literally no air going in or out !!
I managed to pull a piece from his throat, luckily I could get a grip on it.
Trouble is with these is that they swell as they are chewed & get wet.
NEVER AGAIN, imagine if I had given him the chew & gone out :!: doesn't bear thinking about.
