hi my name is Anita I'm in my 30s I have 3 kids ages 17,16 and 14. I have been married 18 YEARS! My hubby is MY BEST FRIEND! Oh Yeah we have 3 dogs! and 3 horses!I LOVE DISNEYLAND! Also love SF and good food.
1. To keep this Disney I'd say ask Mickey about Pluto.
2. For real I'd ask is your York a puppy? They tend to be easier to train.
3. Did you let the dogs smell each others bum?
4. I think PetCo and PetsMart have training.
5. Personal experience has taught me to socialize my dogs with other people and dogs. Say a dog park or visit friends or family who are dog friendly.
Best of luck! And PS y More...
