I am pretty lucky that my greyhound doesn't like real rawhide to chew on. I have tried every type and she just looks at me like "And?" I am careful with what she does get. She doesn't like the Nylabones either, I even ordered the petsafe-chocolate flavored one from Petsmart.com and she didn't even flinch!!
She does like the pig ears and the cow ears. I found on some pet supplies stores carry pig ear pieces, which last long cause they are smaller and I just give her one or two instead of the big ear.
I totally missed the puppy stage of Shaianne, which is the case of most greyhound owners, she was 2 when I got her, and I love puppy breath too!
But I am glad we didn't have to deal with the chewing stage-just separation anxiety.!!! :-)
