at4101, is that your puppy in your avatar? If so, what a cute combination! The Jack Russell and Beagle go well together.
Maybe it is a Jack Russell thing. I can't even bring in the mail without it getting a sniff inspection first. She will follow me, jumping up and down to see it. Once I let her have the sniff, she is satisfied.
We bought a new toilet seat a few weeks ago. The bag was on the floor in my Mom's room. Misha visited it several times. She had to know what was in that bag!
I agree that at times it can be annoying. Sometimes when I'm sitting on the couch looking through something she has to jump up on my lap and stick her nose in to see what it is.
