I know they are there!

Even though the treats are inside plastic he can smell them, they are twisty chickeny things that they got for Christmas. Dried so they last for months but he knows they are there. Because we are still doing up bits of furniture the dining chairs are against the trolley and sideboard so he can get closer than normal to them.
We did, of course, give both of them chickeny treats but didn't stop him going back again. No, he didn't get two, maybe another one tomorrow.
