Ok, i got my first Yorkie back in like late march early april, a little girl.
Well my sister had gotten my niece a little yorkie boy for her bday in december. That was a HUGE mistake as my sister does not like animals. She does this alot, gets her kids an animal and then takes it away.
Well I felt really bad for my niece so i ourchased him from my sister so that way at least my niece would still be able to see him. She loves him so much.
Ok I have a few questions as top how to care for this little guy.
he will be 1 in November, he is NOT potty trained at all, my sister never took the time with him, if my niece was at school or at her dads, my sister never did anything for the porr little guy. So how do I get him housebroken, what method should I use? Also he has a bit of an attitude, he will growl at you, and I do understand that this all comes from the way my sister treated the poor little thing.
he weighs like 4.2 pounds and he is just hiking that leg up on everything, i ahve never gotten a male before that wasnt a young little puppy, and I do know that he is still a pup and can learn this, but i just dont know how to housebreak a little boy, how do i correct him when I catch him hiking that leg? i dont want to overwhelm him since he didnt have it very good with my sister.
oh what about a name change, do you think he could adjust to having his name changed??
Thanks
