Sounds like Rocky has bonded with your Husband instead of you? He sounds like a typical machismo male. When I got my Artie, he was already 20 weeks old. The Breeder that I purchased him from, purchased him to breed w/her 3 females, unfortunately for her he grew too big for her purposes. He is 6 lbs. and 14 months old now. He started traveling by car/plane only after 2 weeks he hardly had time to settle down? He has been thru busy airports, cocktail/dinner parties, BBQ's, Flea Markets, surfing @ Coco Beach, floating on an air mattress in the middle of Lake Shasta. He has been around children from infants to teens and we take our daily walk with a 80 yr. old friend who has an 8 yr. old Yorkie/senior male. He seems to know who he can be rough with and who he needs to be delicate with? Every day he goes to the Dog Park here in Myrtle Beach, SC. He runs up to every dog and human with no fear and he never backs down, they have their own language! Rocky's young enough that there's hope, you have to Socialize him in every situation. Even with other dogs and animals. Artie has also been around skunks, racoons, cats, squirrels, even mules/horses. I think you need to decide what kind of pet do you really want? There are 2 sides to every story, a catch22. Since he is so well socialized we can't go anywhere in a hurry, he want's to greet and see everyone and if he is off his leash, he will run towards anyone not safe in this day and age for obvious reasons. He is an Angel and I don't have any problems,
because I understand his behavior. Both Petco and Petsmart told me not to bother putting him in the Puppy Class. So I did'nt! Just remember that every moment is Training to them. They are always learning from you, you are their example. I hope things work out.....you should also think about getting him nuetered as soon as he is old enough? That helps their temperment alot. It also sounds like you are not the pack leader in his eyes? Let us know how it goes with the Trainer? I'm curious what his diagnosis is of your situation?
I know we lead by example, I know you have to be Alpha. Artie is so sensitive that he can tell by my voice what I expect of him, not only what or how I say it, my tone, my mood, etc. These are great dogs/pets/fur persons if they are trained properly. As cute and cuddly, sweet, adorable and lovable they can be manipulating, sneaky and down right honory/stubborn! I can assure you of 2 things, one is the first year is the hardest, they mellow out afterwards and lastly no matter how much we dress them in cute outfits and even bows they are still males and terriers, even if they're only 6 pounds! Good Luck!
