I don't really have too much advice b/c I have 2 already. They are 2.5 and they are the best thing for each other! They play and they fight, but they also keep each other occupied and company. They both love to be with me, but if I have stuff to do around the, they stay with each other.
When I was looking for them, my DH (live in boyfriend at the time), made me wait a few months until I sold my car and then I could get them. Well, months were going by and my car wasn't selling. Then one day I decided to go online and start to look for puppies. After a few days I found my TJ and Roxy and I was IN LOVE

and I had to have them. I contacted the breeder and got the info. Then I printed HUGE photos of them and placed them in front of my DH and told him everything I knew, BUT that if we didn't act ASAP, they'd be going to someone else
Later that night he handed me with a envelope - it was filled with money for Yorkies!!!!
It was the best decision ever. Roxy and TJ LOVE each other so much! Just a quick story: Roxy had to have LP surgery last year. She was at the hospital for 3 night and 4 days. My DH took TJ to work with him (he drives around all day to Landscape estimates and sets up crews, etc.) He said TJ was a complete MOPE! And when TJ was home, I could barly get him to eat, and to top it all off - TJ went on a POOP STRIKE. TJ didn't poop the whole time Roxy was gone - 4 days! I had to schedule an appt. for an enima the morning of the 5th. THANK GOD, when Roxy came home the night before TJ enima appt. - He pooped within 10 mins. of seeing and kissing her all over!
There is def. a bond between them that's for sure!
Best of Luck! Keep us posted!
