Your boy looks lovely!
My present whippet, now six, is a joy but I remember when he was an 8 week old puppy!
I was seriously questioning my sanity for awhile but was worth it in the end.
I take my boy to work every day and he sleeps in his daybed all day.
Whippets are very missunderstood, most people think they are hyper but I've never owned one.
I tell people that if they want a good watch dog, don't get a whippet.
