Sounds like a typical greyhound puppy to me they don't call them land sharks for nothing. We have never had the energy for a greyhound puppy, but our son got a 'toddler' -- 2 favorite stories -- he said one day someone's alarm on their car in his townhouse addition was going off - it was really irritating him so he finally went outside to find the culprit - shocked that it was his car -- goes in to look for the fob and it's not in its place - finds it, not chewed up, just in carlinda's mouth and she is very innocently looking at him - lol!!! Story 2 - he leaves her for the weekend with a lady friend to babysit - comes home and said friend is quite mad that she has demolished the paperback from her bed table all over in tiny pieces -- our son replied 'sorry - forgot to tell you she's a reader!" Gotta love it. She is now four and a little less wild - still cute as a bug tho!
