I have a 5 month old beagle mix named Sophie, whom we rescued from the humane society. She's been with us since she was 6 weeks old, but is now tall enough to do some serious thievery! She has learned leave it, and if I SEE her doing something she shouldnt and say "leave it" she responds immediately. However, she is a sneaky little thing and if I don't have my eye on her every second, she is shredding paper, facial tissues are her favorite, but she will go for toilet paper, mail or discarded wrapper that hasn't made it to the trash can. The dog ate my homework comes to mind, as she has gotten my son's homework folder off the table before, luckily we've caught her before she got a chance to shred. Also food...she goes for all food! We do not feed her any people food at all, but she sneaks it when she can. I made my son a sandwich the other day and called him to the table, he was washing his hands in the kitchen and I went to pour him a glass of milk..when we turned around the top of the sandwich was mysteriously missing! so nice of her to leave some for him don't you think? at least she shares! lol Now like I said she will respond to leave it but you have to see her do it! At Thanksgiving I was frying celery and onion in bacon grease for the stuffing and when I went to scoop it out of the pan a big glob fell on the floor, she lunged and I said "LEAVE IT" not wanting her to be burned...she immediately sat down and did not try to get the bacon smelling glob! I was very proud of her! and she got a treat and a good girl after I was done cleaning up the mess. So you see she does respond to leave it, but she is sneaky and goes for it when my back is turned...fast too...can swipe a sandwich or a christmas card off the table and be behind the couch in the blink of an eye lol. Any suggestions on how to curb her thievery??
