Our corgi doesn't like fishy things, so I won't even try buying them. I don't buy things for just one of them specifically. They both get the same things to prevent jealousy issues--and those will develop even when one won't touch it. Then you end up double treating the other b/c the picky one walked away from it and the piggy one grabs it before you can.
I gave the link to my daughter-in-law though. It says "pickiest of pups" but I don't see why you can't give them to cats to chew on too. I'll let you know if she tries them.
